Engineering support of drilling fluids

Drilling fluids play an enormous role in the construction of oil and gas wells, starting with the cleaning of the wellbore from cuttings and warnings from geological complications and emergencies, ending with a qualitative opening of the productive formation and further high rate of production well flow.

Non-destructive Testing

Non-destructive testing is used in the manufacturing, installation, repair, reconstruction and technical diagnosis.


One of the main activities of our company is the manufacture of parts and assembly units of any industry.

MWD system called ‘Target’

Телеметрия Target

PetroTool has developed and manufactured MWD system called ‘Target’. It is designed for real-time control of drilling direction parameters of directional and horizontal wells using electromagnetic (EM) link and for formation gamma-ray shooting. Directional Drilling Branch also has following MWD tools with hydraulic link : «PDT» (Pulse Directional Technologies, Canada) and «SureShot» (APS Technology Inc., USA).

The company develops Near Bit ‘Target’ sub and resistivity meter. Also works on MWD tool with electromagnetic (em) and mud-pulse (mp) link association in one tool that will significantly increase the scope of the ‘Target' system.

‘Target’ MWD tool measuring parameters:

• Inclination angle;

• Tool face position;

• Azimuth angle;

• Generator RPM;

• Formation gamma-ray radiation;

• Downhole shock levels.

‘Target’ MWD tool features:

• Drilling with BHA rotation is allowed;

• Titanium generator design is available (500 hours turnaround time);

• ‘Target MWD’ software provided (with ability to store data in .las, .csv, gamma-ray logging in .pdf, through WITS data transmission);

• Gravitational and magnetic axis raw values real-time issuing available;

• On bottom frequency change available.
