Geophysical Services

The Nefteyugansk branch also includes the Buzuluk geophysical expedition, which began its work in late 2016. The expedition, numbering 80 people and based in the city of Buzuluk, has 6 production lots of TACs. Shooting and blasting operations are carried out mainly at the fields of PJSC Orenburgneft in the Orenburg and Samara regions.

The Krasnoyarsk branch of 60 people is based on the Vankor field. AUP is located in the city of Krasnoyarsk. Includes 10 production batches. The main Customer is CJSC Vankorneft and CJSC East Siberian Oil Company. Research is conducted mainly at the Vankor and Yurubcheno-Tokhomsk deposits.

Research is carried out in any climatic conditions using modern equipment. Data transmission is carried out via satellite communication channels, with subsequent operational interpretation and issuance of an opinion.

Types of geophysical research and work performed by JSC “BVT”

• Posting and exploration of drilled directional and horizontal wells;

• Determination of the spatial position of the wellbore.

After the descent of the column:

• Studying the technical condition of wells;
• Control of well cementing technology;
• Clarification of the location and condition of downhole equipment.

Perforation:

• Secondary opening of reservoirs;
• Cumulative perforation.

Under development control:

• Monitoring the current development of reservoirs;
• Determination of oil-water contact in productive intervals;
• Determination of the profile of the inflow of producing and injectivity of injection wells;
• Identification of annular circulation;
• Assessment of the condition of production casing.

Well development work:

• Swabbing;
• Determination of levels and composition of fluids in wells;
• Intensification of injectivity and oil recovery.

Interpretation:

• Geological interpretation of the results of geophysical research;
• Transmission of geophysical research data via electronic communication channels;
• Processing and interpretation of materials in the Prime system.
