High-density 3D survey in Eastern Siberia

• Increasing the detail of structural plans
• Identifying low-amplitude faults and small-sized geological objects in plan and in section
• Preliminary forecast of reservoir development zones, their claying and formation saturation
• Making operational decisions on the placement of exploratory drilling wells
• The quality of the processing and interpretation results ensures a confident solution to geological problems

Use of vibroseismic survey method for recording high-density seismic data:

• high productivity in the amount of more than 2,500 physical observations per day
• the number of traces per km² of survey amounted to more than 3,700,000 units
• use of 40,000 active channels to obtain the most clear and detailed data with minimal distortion.
• data segmentation and detailed analysis aimed at refining the structural plans of the study area.

Use of UniQ technology at the facility allowed for accurate identify the boundaries of different geological layers and their thickness. The high resolution of high-density broadband seismic surveys provided detailed fault locations, which was important for risk assessment and drilling planning. Identification of low-amplitude faults and small geological features both in plan and in section contributed to a more accurate understanding of the subsurface geology.

The data obtained through the study was integrated into the process of operational planning of exploration drilling, which more accurately determines the directions when laying a well.

Improving the quality of data interpretation due to high accuracy minimized the risk of errors at the analysis stage.
