Import Substitution in Action: TAGRAS Geophysical Division Reached a New Technological Level
The Russian oilfield services sector is making a significant technological step forward. The geophysical division of TAGRAS Holding has developed several high-tech solutions for the study and development of oil and gas wells.
These are technologies that were previously supplied to the market mainly by international service companies.
Perforation Control Equipment
With its help, employees conducted tests on a real well. Specialists were able to record perforator depth correlation and perform perforation.
Typically, these operations are carried out separately. The new approach makes it possible to reduce drilling crew time and lower well construction costs.
Downhole Camera with Real-Time Video
A downhole video camera was also developed, capable of operating at temperatures up to 105 °C. The camera transmits video in real time via cable at a rate of 15 frames per second.
This allows specialists to literally look inside the well, assess the condition of the walls and the quality of reservoir exposure. It is also important that similar equipment is currently hardly produced in Russia.
SKAT Tool Line Development
Another downhole tool is SKAT. A new modification will soon allow operation at temperatures up to 180 °C, compared to 150 °C for previous versions.
Such solutions are especially востребованы for deep and high-temperature wells.
Autonomous Module for Offshore Wells
“The main innovative breakthrough is the development of an autonomous well logging module using INGKS equipment, which makes it possible to determine saturation and mineral composition of rocks,” said Alik Imaev, Head of the Scientific and Technical Department of the division.
The module allows geophysicists to:
- determine rock saturation;
- analyze mineral composition;
- store research data.
Such technology is particularly important for remote offshore projects, for example in Sakhalin, where the presence of specialists on drilling rigs is limited.
According to the developers, similar solutions were previously available only from major international oilfield service companies.
This year, work is planned to begin on the development of a near-bit module with a lateral electrical logging sensor, which will allow observation of formations during drilling.
The device will measure rock resistivity directly near the bit — during drilling, not after.
“Comprehensive analysis has confirmed the prospects of this development. Such solutions are not available on the Russian market,” Imaev noted.
This gives geophysicists the ability to:
- obtain real-time formation data;
- guide the well trajectory more accurately;
- avoid missing oil-bearing intervals.
