Seismic surveys

JSC YUZHMORGEOLOGIYA provides fundamental and applied offshore seismic surveys, as a part of governmental programs and as a business projects, develops and implements tools and technologies of seismic surveys.

We executing the following governmental programs:

Timing section fragment (Northern Caspian)
Timing section fragment (Northern Caspian)
  • «Russian sector of the Azov Sea regional survey focused on the oil & gas presence determination and seabed delimitation”
  • «Northern Caspian regional survey focused on oil & gas presence outlook»

We are conducting seismic surveys in the Azov Sea and the Caspian Sea since 1999

Our business activities related to the sesmic:

2D/3D seismic surveys - in transition zones, offshore areas with water depth up to 30 m and onshore – as the main part of hydrocarbons exploration. The surveys executes using high-performance equipment: “BOX” recording system by FairField (1500 channels), ARAM ARIES II recording system by INOVA (24000 channels), Marsh line recording system, Bolt LL and Puls 6 seismic sources. The company provides online QC and onboard data processing using 2D/3D GeoCluster-3100 processing system by CGG. Surveys always performing using DGPS navigation system.

High resolution CDP seismic as a part of engineering survey in transition zones and offshore areas.

The main objective – obtaining of the detailed information for upper parts of the geological section with targeting depth less than 1000m focused on the possible structures and gas anomalies determination and delineation, which could be the possible threat during communications constructing, drilling and other activities (tectonic disturbances, gas pockets, buried erosional incisions etc.).

Acquisition scale — up to М:1000.

Geological section observation depth – not less than 1000m under seafloor.

Following resolution could be provided:

  • For depth up to 500 m – not less than 5 m
  • From 500m to 1000 m – 10 m (main frequencies – 80-140 Hz)

Lines network: according to acquisition scale, from М 1:10000.

Seismic HF CDP profiling performs using wing deployment system with the towing speed of 2-4 knots. Nominal fold:  24 — 48. Online QC and onboard data processing of CDP timing sections.
