1. INTRODUCTION.
Well 7321/9-1 located in the Bjørnøya II area was spudded
26.11.88 and reached T.D. at 1800 m in siltstone of Carnian
age. The well location is given in Figure 1.1
and the well summary outlining formation tops is given in
Figure 1.2.
Based on the geochemical screening analyses by Norsk Hydro
Research Center (L. Aakvaag and N. Telnaes), 52 drill
cuttings and core samples were selected for further
analysis. A list of the samples investigated is given in
Table 1.1.
This report comprises the results from petroleum geochemical
analyses of 52 DCs and CCs. Extraction and group type
separation have been undertaken by Geochem Laboratories
(Chester, UK). Vitrinite reflectance, visual kerogen and
Spore Colour Indices (SCI) have been analysed by Robertson
Research (North Wales, UK). In addition to this Geo-optics
(Northumberland, UK) have analysed a parallel set of samples
for vitrinite reflectance. Stable isotopic composition of
fractions and kerogen have been analysed by Geolab Nor
(Trondheim, Norway). All pyrolysis, gas chromatographic
analysis of saturated and aromatic hydrocarbons, pyrolysis
gas chromatography, biomarker analysis, and the
interpretation of data and compilation of this report was
undertaken by Norsk Hydro Research Center, Bergen Norway.

The relative distribution of the analysed SAT-biomarkers
are presented in bargraphs,- measured as peak heights and
normalized to the most abundant compound:
Data are listed in Appendix la.
Bargraphs are presented in Appendix Ib.
This semi-quantitative presentation is strictly related
to the analytical method.
The concentration/response-ratio is not necessarily
comparable between different type of compounds. A
quantitative comparison of biomarker distributions are
hence restricted to a narrow range of concentrations.
The analysed SAT-biomarkers, presented in the included
bargraphs, are abbreviated accordingly:

2 INTRODUCTION
This report presents the results obtained from spore colouration, vitrinitereflectivity and visual kerogen type analysis of ditch cuttings samples and oneconventional core sample from the interval 700m to ISOOmTD in the Barents Sea7321/9-1 well. The work was submitted by Norsk Hydro, Harstad, under ContractNo. K02815-00/UP-U015.
The group of samples comprised 45 washed ditch cuttings and one piece ofconventional core, and were received at The Robertson Group's North Waleslaboratories on 8th February, 1989. Preliminary results were sent to NorskHydro on 11th March and 11th April, 1989 by facsimile messages. The analysescarried out are as follows:
No. of samples
Sample preparation 46Kerogen preparation 46Spore colouration 29Vitrinite reflectivity - 21Visual kerogen typing * . 29
Robertson Group personnel involved in the study were:
Alan Collins - Project co-ordination, spore colour/kerogen microscopy andreport writing
Sandra Martin - Vitrinite microscopyMalcolm Jones - Supervision of kerogen preparation
Our contact at Norsk Hydro throughout the project has been Jan Augustson whokindly provided the outline stratigraphy and temperature data used in thereport.

APPENDIX 2
ANALYTICAL PROCEDURES AMD TECHNIQUES
This appendix summarises che main steps in the analyses carried ouc in the Robertson Research International Ltd.
petroleum geochemistry laboratories. Analytical pathways are shown on the flow chart (Appendix Figure 1) and details of
laboratory procedures and techniques are given in the text. These aay in certain circumstances be adapted to suit
particular samples or conditions. Interpretation guidelines are also defined.
1. Sample Preparation
General
Samples are received into the laboratories in the forms of well-site canned ditch cuttings, bagged ditch cuttings in
various stages of preparation from wet, unwashed to dried, washed; sidewall cores, conventional cores, outcrop samples,
crude oil samples and gas samples. Each sample is assigned a number which is entered into a computer system to monitor
sample selection and progress. Preparation techniques are directed towards obtaining clean samples, free of drilling
mud and mud additives, obvious caving contamination and indeterminate fine material. Washing with cold water is
standard but further washing with solvene (dichloromethana, DCM) is carried ouc if oil-based mud is present, after which
samples are dried, described and individual lithologies hand-picked where practicable. Samples are rough crushed to
approximately pea-sized fragments for kerogen preparation or finely milled for chemical analysis.
Kerogen Preparation
Kerogen concentrates for microscopic examination and elemental analysis are prepared using standard palynologieal
procedures but omitting oxidation or acetolysis. Acid maceration involves the usa of hot hydrochloric acid (HC1) to
remove carbonates and hot 60Z hydrofluoric acid (HF) to remove or break down silicates. Mineral residues are separated
from the kerogen by a combination of ultrasonic vibration and zinc bromide flotation. Kerogen samples for spora colour
and kerogen typing ara mounted on glass slides in glycerin jelly, those for vitrinite reflectivity are dried and mounted
in epoxy resin. Kerogen residues are stored in methanol.
2. Maturity Evaluation
The techniques employed for interpreting maturity and thermal history in these laboratories are based mainly on spore
colouration and vitrinite reflectivity measurement, supplemented by data obtained from airspace gas and gasoline
analysis, pyrolysis Tmax, and hydrocarbon analysis including gas chrontaCography and gas chromatography-aass
spectrometry.
Spore Colouration
Sporomorph colour is assessed using a >20y sieved kerogen fraction viewed in transmitted light on a standard
palynological microscope. Unusual hues are checked using incident blue/07 light fluorescence. Measurement is made by
eye against reference sets of single grain spore mounts and trained operators achieve a high degree of accuracy and
reproducibility. The 1 to 10 Spore Colour Index (SCI) scale was designed for linearity with increasing depth and
temperature and correlates approximately with tha following zones of oil generation: 1.0 to 3.5, immature; 3.5 to 5.0,
early mature, generation of lov gravity oils (28 to 35 "API); 5.0 to 7.0, middle mature, generation of medium gravity
oils (35 to 42"API); 7.0 to 3.5, late mature, generation of light oils (>42"A?I) and condensates; 3.5 to 10, post
mature, generation of condensate, wac gas and, ultimately, dry gas. Linearity of scale i3 of great value in prediction,
by extrapolation, of the depth to any part of the oil generation sequence. The value of SCI measurement lies in tha
objective selection of measured grains, so minimising problems of caving and reworking, and in its more direct
correlation against oil generation than vitrinite reflectivity measurement. Limitations in its usa concern the
difficulty of correlation against other colour scales and the insensitivity of the scala in the late to post mature
region. Anomalous colours may result from bleaching or staining during deposition and diagenasis. The correlation of
SCI against Thermal Alteration Index (TAI) given on the SCI versus depth plot in the reports was made by direct
comparison of Staplin's standard slides with SCI standard slides.
Vitrinite Reflectivity
The majority of preparations examined under reflected light in these laboratories ara made using >20u sieved kerogen,
mounted in resin blocks and polished with carborundum and alumina although total kerogen may be used when sample size is
1.i
RobertsonGroup
limited. Picked coals, organic-rich shales or limestones containing solid bitumen are mounted directly in resin blocks
; and polished in the usual vay. Measurement is made on a Leirz Orthoplan microscope fitted with an MPV Compact
photometer which feeds values direct to a desk top computer for data processing from each sample. The system is
calibrated against glass standards and reflectance values are expressed as arithmetic means of measurements taken in oil
| immersion (R or R . . ) . R and R . may be measured and quoted in certain circumstances but the difference isI o m oil max sun
> insignificant belov about R l.QZ. Some operator selection of particles during measurement is essential and obvious
contaminants or aon-vitrinitlc material are noted but not necessarily quoted. The value quoted on data cables is that
< which is interpreted as most appropriate, but other possibilities may also be given. Plotted figures assume a
logarithmic increase of reflectance with depth. R 0.5% is a widely accepted threshold value for the onset of oil
generation, although as Che kinetics of oil generation may not be identical co chose of vicrinite reflectivity
development this must be seen only as a general guide. The floor for oil generation is characterised by a reflectance
value of about 1.3%. Wet gas generation peaks at a value of about 12 and ceases at the IX level. Dry gas generation
peaks at a reflectance of about 1.5Z and ceases at the 3Z co 4Z level. Correlation of reflectance values with other
maturity parameters may not be universal because of cime-cemperature factors and is best made on a local basis.
Reflectivity measurement is a widely used and versatile tool which may be readily calibrated against easily obtained
standards. It is applicable over a wide range of maturity stages from immature to post mature (0.2Z Co 5Z R ) . High
surface intercepts on plotted figures and discordances at faults and unconformities can give realistic estimates of the
amount of section missing. It is of limited value in Early Palaeozoic sections where land plant material is absent,
although a general guide to maturity may be obtained from chitinous organic matter. Even a skilled operator may have
difficulty in distinguishing indigenous vitrinite from some forms of inertinita, anomalously reflecting
"pseudovitrinite", cavings and reworked fragments.
Airspace Gas Analysis
Vet cuttings are collected at Che wall site and sealed in partly full cans containing bactaricide. In the laboratory,
the airspace (headspace) gas is extracted using a can piercer fitted with a 3eptum and analysed by gas chroinatography.
The proportions of methane, ethane, propane, iso— and n_— butane are calculated from integrated peak areas by comparison
with a standard mixture of these gases. Methane is the dominant gas in immature and post mature sediments, comprising
90-100Z of total gas, falling to 3O-7OZ in mature sediments. The onset of maturity for oil generation (SCI 3.5) is
characteristically marked by an increase in wet gas (C.-C,) to between 10 and 20Z with further increases in maturity
indicated by a decrease in the ratio of iso- to o-butane. Ratios of >1.0 are typical for immature sediments and <0.5
are usual in mature sediments. Departures from composition versus depth Crends may be useful in indicating migrant gas
at faults, unconformities or reservoir rocks but limit the method as a reliable maturity indicator. Airspace gas
analysis is an inexpensive and rapidly executed method of screening samples for further maturity and hydrocarbon content
determinations.
Gasoline Analysis and Cuttings Gas Analysis
Cuttings samples received wet, preferably in sealed containers, are suitable for gasoline and cuttings gas analysis. A
portion of the washed cuttings sample is retained wet, pulverised in a sealed shaker and warmed to expel the C. to C.
hydrocarbon components into the shaker airspace. A sample of this airspace gas is then removed and analysed by gas
chromacography either for cuttings gas (C, to C.) or gasolines (C, to C.). Op Co 28 hydrocarbon components are
identified in Che C^ co C? range and their relative proportions calculated from integrated peak areas with reference co
standard mixtures. Immature source rocks yield low total abundances and limited numbers of components whereas mature
source rocks usually contain a full complement of identified hydrocarbons with the onset of maturity indicated by a
rapid rise in total gasoline abundances with depth. Anomalous amounts of gasolines may mark the presence of oil stain.
Gasolines may be used in oil to oil or oil to source rock correlations but the concentration of some of the measured
components is not only a function of source but also depends on maturity, migration and alteration in the reservoir.
Using the most stable compounds» pairs with similar chemical structure and boiling points are reduced co pair ratios and
compared with the same pair ratios in other oils or possible source rocks. Gasoline analysis is a valuable tool in that
it measures directly che hydrocarbons being generated from a sediment but its sensitivity in detecting traces of oil
places constraints on its use as a maturity indicator.
2.2
RobertsonGroup
Rock-Eval Pyrolysis, Gas Chromatography (GO aad Gas Chromatography-Mass Spectroraetry (GC-MS) in Maturity Analysis
These chree analytical processes measure parameters which are functions of both maturity and kerogen type. Data from
them may give a general guide to maturity but if the kerogen types are known, more specific conclusions may be drawn.
From Rock-Eval data, the temperature of maximum rate of pyrolysis, Tmax, is the most useful datum; gas chromatograms of
alkanes, separated from source rock extracts or oils, yield carbon preference indices (CPI) and isoprenoid ratios; GC-MS
quantitative fragmentograms provide abundance ratios for specific compounds which are particularly useful in assessing
the level of maturity at which source rock hydrocarbons or oils have been generated. All these supplementary data may
be used to confirm results from visual analysis or supplant them if poor or unavailable.
3. Source Rock Evaluation
Total Organic Carbon Content (TOC)
Organic carbon values are obtained by treating O.lg of crushed rock sample with hot, concentrated HC1 to remove
carbonates. The washed residue is filtered on to a glass fibre pad and ignited in a Leco carbon analyser. For
screening purposes, samples are analysed singly but where further analyses, such as pyrolysis or solvent extraction are
anticipated, a duplicate sample is run. Blanks and standards are run as routine and where values from duplicated
samples do not concur within strict accuracy limits, they are rerun. Where samples are heavily stained with oil, either
from natural deposits or drilling mud, TOC is repeated on the dried, solvent extracted sample.
TOC measurement is fundamental in assessing source rock quality since when combined with kerogen typa and maturity, a
full description of the potential to generate oil may be given. It is found in practice that sediments containing less
than 0.3Z TOC are unlikely to have any source potential, those containing between 0.3Z and 1% may ba marginal sources
but the better quality sources contain in excess of 12 TOC. Screening by TOC is therefore an inexpensive and rapid
method of selection of samples for further analysis in source potential evaluation.
Rock-Eval Pyrolysis
Pyrolysis data are obtained using the IFP-Fina Rock-Eval apparatus. 100 og of crushed, whole rock either from bulk
sample or picked lichology is weighed accurately into a crucible and introduced into a furnace at 250"C. Free
hydrocarbons (roughly equivalent to solvent extractabla hydrocarbons) ara volatilised and quantified by flame ionisation
detector (FID) to give Peak I (S,, ppm). The furnace temperature is increased to 550°C at 25°C/minute and within this
range, kerogens crack to giva hydrocarbons, measured by FID to give Peak 2 (S., ppm) and carbon dioxide, measured by
thermal conductivity detector (TCD) to give Peak 3 (S-, ppm). The temperature at the maximum rate of evolution of
cracked volatiles (Tmax) i3 measured automatically but can also ba monitored visually. The instrument is calibrated
daily using standards both at the beginning of the work period and at regular intervals thereafter and crucible blanks
are run as routine. The tabulated data in reports comprise the following parameters:
Tmax °C - temperature of maximum rate of Peak 2 hydrocarbon evolution.
Hydrogen Index (HI) - S./TOC (mg/g) or ratio of released hydrocarbon to organic carbon concent. This is a measure of
the hydrocarbon generating potential remaining in the kerogen as opposed to thac of the whole
rock.
Oxygen Index (01) - S./TOC (mg/g) or ratio of released carbon dioxide to organic carbon content.
Production Index (PI)- S./S.+S,, or ratio of the amount of hydrocarbons released in the first staga of heating to the
total amount of hydrocarbons released and cracked during pyrolysis.
Potential Yield (PY) - S. (ppm) or total of hydrocarbons released during cracking of karogen compared to original
weight of rock.
Tmax, hydrogen index and oxygen index are each functions of both maturity and kerogen typa. Using published and
empirical data, it has been possible to assemble a model to show the relationships of these factors co maturity as
measured by spore colouration and vitrinite reflectivity for a selection of pure kerogen types. The kerogen types used
are algal sapropel (type I), waxy sapropel (type II), vitrinite (type IIIA) and inertinite (type IIIB) and a computer
program has been devised by which the amounts of these components may be calculated from the HI, 01, Tmax and maturity
2.3 RobertsonGroup
. data for any sample. These are Che values expressed in che "kerogen composition by calculation" columns tabulated in'
| che reports.
The hydrogen index is a measure of the hydrocarbon generating potential of the kerogen and is analogous to the atomic
i H/C ratio. Immature, organically rich source rocks and oil shales give values above 500, mature oil source rocks give
' values between 200 and 550. For a given kerogen type, these values progressively diminish with increasing maturity.
' The cemperature of maximum rate of pyrolysis depends partly on the kerogeo type but the transition from immature co
J mature organic matter is marked by temperatures between 415° and 435°C. The maturity transition from oil and wet gas
generation to dry gas generation is marked by temperatures between 455° and 460°C. In practice, greater variation than
J these ideal temperature ranges may ba seen, but they are nevertheless useful as general guides to the level of maturity
attained by the sediment.
i The production index increases with maturity from values near zero for immature organic matter to maiffunmi values of 0.15
t during the late stages of oil generation. Anomalously high values indicate the presence of oil or contaminants. The
potential yield is an indication of the predicted yield of hydrocarbons from the source rock at optimum maturity and is
, a measure of the quality of the source rock. For immature sediments, values of 0 to 2000 ppm of hydrocarbon
t characterise a poor source rock, 2000 to 6000 ppm fair, 6000 to 20 000 ppm good and above 20 000 ppm very good.
Pyrolysis techniques have in recent years provided a major advance in the assessment of source rock quality and
j generating potential. Hydrocarbon yields from immature source beds examined on-structure may be translated into actual
oil productivity from the same beds in mature basinal, off-structure situations. Models relating maturity and kerogen
type may be used to define original 3ource rock quality grades which are of great value in mapping organic facies.
j ' Amorphous kerogen types, indistinguishable in microscopic preparations over a wide range of chemical properties, may be
| readily differentiated by pyrolysis. The problem of analysing bulk samples containing mixed kerogens has been largely
overcome by the kerogen type/maturity model and anomalous results arising from the presence of caving contamination and
I drilling mud additives can usually be explained by inspection. High oxygen indices sometimes occur as a result of the
• presence of metastable carbonates and in such cases the sample is acid decarbonated and re-run.
Visual Explanation of Kerogen Concentrates
All palynological preparations on which SCI determinations are made are also examined ror kerogen type. Visual
estimations of che relative abundance of the broad groups vitrinlte, inertinite and sapropel are made on the total
kerogen slide mount but reference is also made to the >20u 3ieved fraction to assist in identification. The scheme of
identification is shown in Appendix Table 1. Full use is made of incident blue or UV light in distinguishing Immature
' or early mature oil-prone kerogen from gas-prone kerogen.
j Extract Analysis
The soluble organic materials present in rocks can be extracted with organic solvents, fractionated and analysed. The
type and amount of material extracted depends largely upon the nature of the contained kerogen and iC3 maturity,
although the presence of migrant oil or drilling contamination may be the determining factors.
A nmyjmm» of 40g of crushed sample is extracted for a m-in-timm of 12 hours in a Soxhlet apparatus using laboratory
redistilled DCM. The solvent and the more volatile components (approximately up to n-C..) are lost by evaporation in an— 15
air flow and the resulting total extract is weighed, dissolved in hexane and separated into alkane (saturate)
hydrocarbon, aromatic hydrocarbon, resene and asphaltene (polar) fractions by silica adsorption chromatography in che
Iatroscan process.
Larger fractions, suitable for further analysis, are obtained by column chromatography. The extract is run through a
short glass column packed with silica and alumina and eluted with hexane (to give the saturate fraction),
(3:1 hexane: toluene mixture (to give the aromatic fraction) and methanol (to give the polar, or resene and asphaltene,
fraction). A small proportion of aon-eluted polar compounds usually remains on che column.

The data tabulated in reports comprise the following parameters:
Total extract - soluble organic matter, heavier than about ji-C,,. , expressed as ppm of weight of rock.
Hydrocarbons - sum of alkane and aromatic hydrocarbons, expressed as ppm of weight of rock.
Extract ™ of organic - total extract ppm; the axtractability.
carbon (EPOC) T 0 C x 1 0°
Hydrocarbons mg/g of
organic carbon - total hydrocarbons normalised to lg of organic carbon.
Hydrocarbons Z extract - total hydrocarbons as a proportion of total extract.
Alkanes Z hydrocarbons - the proportion of alkanes (saturates) in the total hydrocarbons. The proportion of aromatics
is (100 minus chis value) expressed as a percentage.
The excractability of oil-prone 3apropelic organic matter increases rapidly in tha oil generation zone and diminishes to
very low values in post mature sediments. Overall the extractabilicy of sapropelic organic matter is greater than that
of gas-prone humic organic matter for similar Ievel3 of maturity. Samples with, extractabilities of greater than 20Z
generally contain migrant oil or are contaminated with mud additives.
As maturation proceeds in the oil generation zone the proportion of hydrocarbons in tha total extract increases from
less than 202 to a m ^ m m in the most productive horizons of around 601. This trend is reversed as the oil-condensate
zone is entered. The relative proportions of alkanes to aromatiC3 can be used as a check for lov levels of
contamination. Fractions of the extract» separated by column chromatography are retained for further analysis by gas
chromatography or for stable carbon isotope determination.
Capillary Gas Chromatography of C,.Alkanes
A portion of the Soxhlet extract is eluted with hexane through a short silica column to yield the saturate hydrocarbon
fraction. This fraction is evaporated in a stream of dry nitrogen at room temperature. A small portion of the fraction
is then taken up in hexane and introduced into a 25 metre, wall-coated, open tubular glass capillary column coated with
0V-1, or equivalent, mounted in a Carlo Erba gas chromatograph which is temperature programmed from 70"C to 270°C at
3°C/minute.
C..+ chromatograms are inspected for the distributions of ii-alkanes, and the presence and abundance of isoprenoids
(particularly pristane and phytane), steranes and triterpanes and unresolved envelopes of naphthenic compounds. The
ratios pristane:phytane and pristane:n_-C.. are calculated. Carbon Preference Index (CPI) values quoted are those as
defined by Philippi as the ratio 2C-g to (C.g+C-..) unJ-a33 otherwise stated. Chromatography may reveal information about
the kerogen type of the source rock, its maturity and condition of deposition and, if migrant oil is present, whether
this has been water-flushed or biodegraded. Contaminant drilling mud additives may be identified.
Capillary Gas Chromatography of Aromatic and Branched/Cyclic Alkanaa
The aromatic portion of the Soxhlet extract is eluted from a short silica/alumina column by a hexana/toluene mixture.
The dried fraction is taken up in DCM and introduced into a 25 metre, wall-coated, open tubular glass capillary column
coated with QV-l, or equivalent, mounted in a Carlo Erba gas chromatograph which is temperature programmed from 70°C to
27O"C at 3°C/ minute.
Branched chain alkanes are separated from normal alkanes by urea adduction and treated as for total alkanes.
2.5
RobertsonGroup
Gas Chromatography-Mass Sgectrometry
Mass spectrometry is a technique in which molecules are bombarded wich high energy electrons causing ionisacion and
fragmentation of the molecules into ions of varying mass(m) and charge(z). The way in which a molecule fragments into
ions of various m/z value is known as its fragmentation pattern, or mass spectrum and is unique. When linked to a gas
chromatograph the mass spectrometer can be used in tvo different modes:
1. Full Scan Mode: A mass spectrum is obtained of each peak eluting from the gas chromatograph and a structural
identification of the compound producing that peak can be made.
2. Multiple or Single Ion Monitoring Mode: The mass spectrometer is tuned to certain m/z values to detect whether a
compound, eluting from the gas chromatograph, fragments to give an ion at that value. Certain fragmentations are
indicative of specific compound types and the most commonly monitored fragment ions used in petroleum geochemistry
are those with m/z values of 191, 217 and 259 which are cha principal fragment ions obtained from groups of alkanes
known as triterpanes, regular 3teranes and rearranged steranes respectively. These are compounds containing 27 to
35 carbon atoms arranged in a polycyclic, normally 4 or 5 ring, structure, occurring in the n-C_, to u-C,- region— Zo — 35
of a gas chromatogram. The basic molecular skeletons of these compounds are very similar to those of the original
organic matter deposited in the sediment and so these 191, 217 and 259 distribution plots, known as mass
fragmentograms or mass chromatograma, form a pattern characteristic of cha source material. This technique of
"fingerprinting" is also one of the more exact methods of correlating an oil to its source, or to another oil.
Carbon Isotope (13C/12C) Ratio Analysis12 13
Carbon has two stable isotopes, the more abundant C isotope and the heavier C isotope, which in nature forms about
1% of carbon. 'Deviations from the C/ C ratio are extremely small and carbon isotope ratios, as measured by mass
spectrometry, are expressed as deviations from a standard, the Pee Dee Belemnite carbonate (FSB standard) in parts per
thousand (parts per mil; °/oo). Positive deviations indicate C enrichment and conversely, negative deviations
indicate C impoverishment.
While the carbon isotope ratios of oils and rock extracts can range from -20 to -32 °/oo depending on the source organic
matter type, the difference between a specific oil and its source is small. Measurements are usually made on the C,.
alkane and aromatic hydrocarbon fractions separately and there should be no more than 1 /oo difference between the oil
and its source for either fraction. If there is any doubt that the source rock extracts are not indigenous to the
source rock kerogen, the carbon isotope ratio of the extracted source rock kerogen can be measured.
Pyrolvsis-Gas Chromatography
The hydrocarbon pyrolysate derived from thermal, anhydrous cracking of kerogen is analysed by capillary gas
chromatography. A few tug of rock, kerogen or asphaltene is heated to 600"C for 20 seconds in the injector of a gas
chromatograph. The chromatograph oven is kept at -30*C during pyrolysis and then raised to 300°C at a programmed rate
of 7.5°C/minute. Chromatograms produced thi3 way are often very different from those of source rock extracts or oils in
that branched and cyclic isomers are generated freely giving numerous» closely spaced peaks, along with unsaturated,
alkene (olefin) hydrocarbons. The "doublet" peaks often observed in these chromatograms comprise alkene-alkane pairs,
the first eluting, and usually smaller peak, being the alkene. The chromatograma range from C, to C-- or above and
although variable, are broadly characteristic of source rock type. Gas-prone kerogen cracks to give a more limited
molecular weight range of products, concentrated towards the light ends, whereas oil-prona kerogen gives more prominent
alkene-alkane doublets in the C., to C.Q region. The largest peak from both types is usually methane.
Elemental Analysis
Total (unsieved) kerogen is prepared as described in Section 1. The dried material is combusted in oxygen in an
elemental analyser and the oxides of carbon, hydrogen, nitrogen and sulphur are measured. The unburnt residue is the
ash content. Oxygen is usually calculated by difference but can be determined separately if required. Results are
quoted as percentage weights of C, H, 0, N, S and Ash with the atomic ratio B/C and 0/C calculated and plotted on the
standard van Krevelea diagram. The relative amounts of C, H and 0 present in organic matter are dependent on both
source and maturity. At known maturity levels, some measure of source quality may be determined. Limitations of the
method in source rock assessment involve the difficulty of obtaining pure kerogen (in particular, free from pyrite) and
the lack of a simple, direct determination of oxygen content.
2.6 RobertsonGroup
4. Oil Analysis
RRI laboratories offer a wide range of oil analyses both for geochemical purposes and industrial use. Physical
property determinations are based mainly on IP methods and are available for lubricating oils, fuels and greases as well
as crudes. Frequently measured properties of crude oils presented in geochemistry reports include: API gravity, pour
point, viscosity and contents of water, sulphur, wax, asphaltene, nickel, vanadium and other metals. Chemical analysis
of oils involves the following:
Whole oil gas chromatography - using split syringe injection and a temperature programme from -20°C or -30°C up to 270°C
at 4°C/minute.
Associated gas
Gasoline analysis
- if oil has high gas/oil ratio.
- as for gasolines in rock samples but a weighed quantity of oil is used.
Topping of the oil
Column chromatography and
gas chromatography
- this is equivalent to the removal of the fraction boiling below about 210°C and gives a
more standardised product for comparison of gas chromatograms of the C.-, fraction.
- as for solvent extracts. Analysis is. carried out on topped oil.
5. Gas Analysis
The hydrocarbon gases, C. to C,, may ba collected from the airspace of sealed canned samples or may be received from
well-site tests in a special sealed gas cylinder (gas mouse). Chromatographic separation of the C, to C^ gases is
effected as described under airspace gas analysis. In addition, the separated gas components may be analysed for stable
carbon and hydrogen isotope composition which may provide valuable clues to the origin of the gas.
6. Solid Bitumen Analysis
In some oil fields, problems are encountered whara bitumen developments form continuous or patchy layers within
reservoirs, dividing the pay zones and acting as barriers to natural fluid movement or inhibiting enhanced oil recovery
techniques. Integrated geochemical and sediaentological studies aim to produce geological models capable of predicting
the occurrence of bitumen layers and their likely thickness and ability to act as permeability barriers. Of further
concern are the past or present relationships between the bitumen and reservoired oil, their source rocks and the timing
of bitumen formation.
Analysis schemes involve screening of samples by assessing the amount of bitumen in polished core pieces using reflected
light microscopy, followed by solvent extraction of control samples to estimate the proportion of solvent soluble
bitumen. Different phases of bitumen formation are differentiated by reflectance measurement as described for vitrinite
reflectance measurement. Soluble extracts are fractionated to give alkane, aromatics, asphaltene and resene components.
Separated bitumens may be subjected to elemental analysis.

INTRODUCTION
This report comprises the RockEval/TOC results of 295 DC samples
from well 7321/9-1, covering the Cretaceous to the Triassic.
The well was spudded 26.10. 1988, and reached TD at 1800 m (RKB)
in claystones of Norian age.
The well was dry.
EXPERIMENTAL
The wet cutting samples were washed using a 0.125 mm sieve and
dried at 60 °C overnight.
An aliquot of the sample was crushed and analysed using a
RockEval/TOC analyser. A standard was analysed approx. every 10
samples to check the reproducibility of the analysis.
The results are presented in terms of:
S2 : Low temperature oil/gas yield (mgHC/g rock)
52 : Pyrolysis yield (mgHC/g rock)
53 : CO2 yield (mg CO2/g rock)
Tmax : Temperature at which maximum emission of
hydrocarbons occurs
TOC : Total Organic Carbon
HI : Hydrogen Index (100xS2/TOC)
01 : Oxygen Index (100xS3/TOC)
PI : Production Index (S1/S1+S2)
PP : Production Potential (S,+S,)

INTRODUCTION
Three homogenised drill cutting samples from well 7321/9-1 were subjected to hydrouspyrolysis in steel bombs at three different temperatures. 320°C. 340°C and 360°C. Thebiomarker composition based on metastable ion monitoring of teipanes and steranes. of theresulting samples were compared with each other and the biomarker compositions in theoriginal extracts.
The three samples investigated were:970 m980 m1357 m
Particularly the conspicuous low original abundance of rearranged steranes in theBarremian samples was studied in detail.
RESULTS AND DISCUSSION
The extraction yields and results of group type separation is given in Table 1.
