Data acquisition in territories with restricted access

Location: Russia
Monitoring method: Low Frequency Seismic

The Situation

The surface conditions for surveying this area were complicated by the presence of an airport security zone in the north-western part of the work site and the runway itself which made it impossible to carry out conventional 3D seismic survey.

The Approach

The use of independent sensors and passive nature of LFS technology made it possible to successfully carry out LFS field work during quiet operational periods
The map above shows the results from the LFS survey highlighting areas of oil bearing prospects as well as the resulting wells drilled.

Results

  • The LFS survey covered structures adjacent to the previously identified oil reservoir (wells 1-4 in the Figure above). Based on the results of the LFS survey a single oil-prone area was identified, covering the north-western and central uplifts, and extending in a north-western direction under the airport security zone.
  • Well 5 was drilled in the culmination at the centre of the LFS survey. This well was oil-wet with a reservoir as prognosed and predicted by the LFS survey. The next well 6 on the southeastern slope showed only weak oil saturation in the upper part of the reservoir. This result is in-line with the hydrocarbon potential estimate from the LFS survey. Well 6 was sidetracked to the 6_1 location to enter the area of well 5, where oil pay was encountered within the prognosed range, again as prognosed by the LFS survey.
  • Later drilling of well 7 and 8 in between the central and northwestern structures and the confirmation of commercial oil inflows during their testing confirmed the LFS forecast of a more extensive oil saturation contour, covering both structures, including the interdome space.
  • The total net pay in the drilled wells 5, 6_1, 7 and 8 ranged from 7 to 18 m.
