Appearance of Rotary Steerable Systems (RSS)allowed changing of traditional technology andincreasing of techno-economic performance of welldrilling.

One of the components of successfully carrying outdrilling operations with use of RSS is a competentapproach to selection of drilling tools capable to realizeall the potential of this system. Special attention shouldbe given in accounting for two main types of RSSaccording to method of bit displacement control relative

to well axis:1. Push the bit radial displacement of wholeassembly or its major part with respect to well axis;2. Point the bit positioning of bit is achieved bymeans of tilting drive shaft with respect to BHA.

Two different RSS types require widely different bitdesigns.

Lateral and axial loads are accounted for in the cuttingstructures gauge length and its aggressiveness.Cutting structure durability must correspond to RSSrequirements.

BURINTEKH produces bits for both types of RSS.

Bit performance data and drilling companies responsesallow us to proudly state that our bits are competitivewith world manufacturers bits and surpass them insome rates.

Core barrels are designed for coring with downhole hydraulic motor or rotorin formations of I-III category of recovery difculty using core heads equipped

with PDC cutters, thermally stable polycrystalline (TSP), impregnateddiamonds or its combination.

High quality bare pipes of domestic and foreign manufacturers are used inproducing core barrels. All components pass strict quality control. Core barreldesign is multi-purpose and allows using one barrel for coring isolated andnon-isolated core due to using berglass core tubes and insulating uid.

Core Barrel

Disicive desig feares f buRIntEKH, Ld. cre arrels:

Increased body diameter and reinforced threads increase service life andprovide continuous trouble-free operation of core barrel;

Core tube tapered thread considerably speeds up make up and lay downoperations;

Inner core tube suspension design allows making fast clearanceadjustment between core head and inner-tube shoe and, if necessary,change standard heavy series thrust bearing within 10-15 minutes at rig

site;Collet core-cutters have necessary elastic characteristics due to special

heat treatment technology and equipped with high roughness cover oftungsten carbide throughout inside diameter, which provide reliable corecatching during brake-off and pulling-out operations;

The variety of toggle-type core catchers allows selecting overlapped coretube cross-section area depending on type of formation for reliable corekeeping during pulling out operation;

Spiral centralizers decrease vibrations and uctuations and allowincreasing of core recovery percentage in ssured, cavernous and broken

formations.

Reamer stabilizers are produced with two tapered surfaces. Tapered surfaces, reinforced with

tungsten carbide inserts with cutting edge, comprise reaming part of a tool. Letter on nomenclature

designates box-pin type body, letter S spiral blades, L left-hand thread (designated with an

LH at the end of the thread designation), number at the end of code quantity of blades.



Puncher

Designs of all punchers are protected by patents of Russian Federation.

modernized ie uncher ptm is designed for punching 825 mm holes in tubing and casingfrom 60 to 168 mm of domestic and foreign manufacturers to make a communication betweenthe interior cavity and the exterior annular space. This hole provides circulation restoring,prevents pulling pipes with uid out of wellbore, and relling into cement sheath and decreases

environmental pollution while well workover operations.

Punchers are produced of several series: ordinary K, for application in gas medium G, forapplication at depth 3000-6000 m VD.

Punchers are run in a hole on wire, cable, ush-joint pipes or by throwing off.

Potential energy of a uid column and pumping unit pressure are used to actuate a puncher.

JARS



JARS

Our hydraulic and mechanical jars are designed for releasing a stuck downhole tool byup-and-down impacts with static axial load (tension) and torque. Jars are included indrilling assemblies for sidetracking. We produce right and left hand shing and drilling

jars.

Today, we produce a brand-new torsional jars purposed for releasing a stuck tool by up-and-down torsional impacts.

Design of axial jar is own BURINTEKH, Ltd. development protected by Russian andforeign patents.

Main advantages are:

Singular case thread (between body and bottom sub);

Compactness which allows transport it on pickup and deliver it to hard-to-reach areason helicopter without external suspension;

Absence of extreme loads to hydraulic cylinder appearing during jar performance;

Ability of quick repair by changing hydraulic cylinder;

Jars for upward and downward impacts are different tools and can be placed in the

drillstring independently from each other or only one of them.

Hydraulic jaryAGb-172 is produced of several series: ordinary yAGb-172, for rotaryBHA yAGb-172R, for working at high pressure yAGb-172VD.

Axial Jars



toronal Jar sHOCK tURNDesign of torsional jar is own BURINTEKH, Ltd. development protected by Russianand foreign patents.

Why is stuck tool released by only up-and-down impacts along well axis? In fact, lifeexperience suggests that for pulling, for example, driven nail out it is better not onlypull it, but pull with simultaneous turn. Obviously, it is easier to free stuck downholetool if not only axial impact loads but also shock torsion torque are applied. To solvethis challenge, we developed torsional jars SHoCK tuRn, which can affectstuck tool by clockwise and counterclockwise and up-and-down impacts in differentcombinations.

Main advantages are: High power capacity. Torsional jar impact strength 56 times bigger than ordinary

jar;

Singular case thread (between body and bottom sub);

Compactness which allows transport it on pickup and deliver it to hard-to-reachareas on helicopter without external suspension;

Absence of extreme loads to hydraulic cylinder appearing during jar performance;

Ability of quick repair by changing hydraulic cylinder;

Extended functional capabilities.
