Why do we need to employ when we arealready producing oil?

Peak oil is the point in timewhen the maximum rate ofglobal petroleum extractionis reached, after which therate of production enters

terminal decline.

After Peak Oil

A

. . William J. Cummings, Exxon-Mobil company spokesman, December 2005

As Peak Oil is reached all the easily accessible oil has been extracted and further extraction usingconventional extraction techniques will become increasingly expensive.

Finding New Reserves will prove more expensive and less attractive, transportation and refiningcosts are denting profits.


7/51

New Oil Reserves- a viable option?

It is pretty clear that there is not much chance of finding any significant

quantity of new cheap oil. Any new or unconventional oil is going to be

expensive.

Lord Ron Oxburgh, a former chairman of Shell, October 2008

Known - 4 barrels consumed for every 1 barrel discovered.

Conclusion- We need to extract as much oil from known sources

as possible

15-50% of CRUDE OIL IN MOST RESERVOIRS

HOW DO WE ACHIEVE BETTER RESULTS


9/51

: Reservoir drive comes from a number of natural mechanisms.

These include:

1. natural water displacing oil downward into the well,

2. expansion of the natural gas at the top of the reservoir,

3. expansion of gas initially dissolved in the crude oil,

4. gravity drainage resulting from the movement of oil.

, .

During this stage typical oil recovery is between 5-25% of thetotal oil residing in the well.

(525% )


10/51

(1025% )

, . ;

to increase reservoir pressure (replacing or increasing the natural reservoirdrive)

to bring the oil to the surface.

by natural gas injection, gas lift (which injects a mixture of gases intothe bottom of a production well, to reduce the overall density of fluid in the well-bore)

is 10-25% of the total oil residing in the well

Using the best estimates of %yield, we can see that there is at least:

50%

Its a large deposit of stones or

sandstone sandwiched between twolayers of impervious rock. Thehollow spaces between the stonesor sand are filled with thick andviscous oil.

It takes time for oil to ooze fromzones of high pressure to the zoneof low pressure near the pipe.

EMORHistory

1920Claude Zobell

EOR processes were thought as unpredictable with various limiting factors - such

as microbe types, reservoir properties, fluid properties, infrequent testing


18/51

Employing EOR techniques will increase the life and productivity of a well.

Fundamentally, the mechanisms that govern oil release due to beneficialmicrobial growth are very much the same as those proven anddemonstrable chemical and physical effects, derived from well known

EOR techniques.

Our programme can be manipulated to act in a number ofbeneficial ways;

Producing bio-surfactants

Producing bio-polymers Increasing the gas drive

Bio-cracking

Bio-film plugging

Bio-competitive exclusion

An oil field emptiesrapidly at the start and

yields lots of oil.

Then the flowslows downgradually.

Towards the endthe flow eases to

a trickle.

An oil field yields itscontents over the years,

something like this.
