2019: Digital data processing at Lena River

JSC Centralnaya geofizicheskaya ekspedition (TsGE, affiliated enterprise JSC Rosgeo) carries out cameral processing of the materials received during field seismoprospecting works of MOGT 2D on the western slopes of the Nepsko-Botuobinsky antekliza and adjacent territories in Eastern Siberia.

The carried-out seismic works are interesting that they were executed along a river Vitim bed (inflow of Lena) when the line of registration of seismic waves is located ashore, and a point of excitation and acceptance – on the vessel in the river water area. Such specifics impose increased requirements to a technique of field works, to the choice of conditions of excitation and acceptance of waves and also to the specialist supervisor who should understand at the same time features of seismic exploration on the land, in the sea (river) and transitional (transit) zones.

As a result of express data processing control and quality evaluation of field information is executed, preliminary seismic cuts are received. Standard initial field data are transferred to specialists of TsGE for the subsequent cameral processing.

During cameral processing it is going to receive the total and migrated temporary and deep cuts along the river Vitim which together with seysmicheskm the data received on the land will allow to reveal large oil and gas potential objects in rifey-vend-nizhnekembriyskikh terrigenous and carbonate sedimentation complexes.
