Project description:
Detailing the geological structure of the subsurface areas within the work performance areas
The works were carried out
by the research vessel "Academician Primakov"
Project implementation:
2D acquisition: swathe acquisition geometry, Q-Marine Gel towed streamer, 1 streamer of 8000 m (in the field MB-OSHP-2018/1), a distance between the channels: 12.5 m., recording length: 8 seconds.3D acquisition: swathe acquisition geometry, Q-Marine Gel towed streamers, 8 streamers by 8000 m each (in the field MB-OSHP-2018/1) and 8 streamers by 6000 m each (in the field MB-OSHP-2018/2), distance between the channels: 12.5 m., distance between the streamers: 100 m, recording length: 8 seconds.
The seismic streamer submerging was controlled by IRMA system, the modules were located in 400 meters.
2D pneumatic seismic source points:3 pneumatic source lines Bolt 1500LL, 1900LLX, volume: 2 x 3793 cubic inches, distance between the sources: 6 m.
3D pneumatic seismic source points: 2 sources with 3 pneumatic source lines Bolt 1500LL, 1900LLX, volume: 2 x 3793 cubic inches, distance between the sources: 50 meters, depth of submersion: 6 m.
Installation of the streamers and seismic pneumatic source points is performed by monowings for 3D and by barowones for 2D operations.
The positioning of the seismic streamers and seismic pneumatic source points in 3D operations was controlled by IRMA system.
The streamer depth controllers DigiBirds 5011 were applied in performance of 2D operations.
All obtained profile were processed with application of the geophysical processing software package SeisSpace 5000.10.
In addition, the navigation data were completely processed.
There was no complaint with respect to the quality of the produced material from the customer representatives of the board of the research vessel.
