Project type:
2D Seismic Surveys
Location:
Ghana
Year:
2018
Environment:
Deep Offshore
Size:
5,445 km

5,445 km of MC2D seismic data acquired offshore Ghana as a part of WEASPAN™ project, in partnership with ION. PSTM data available Q3 2018. Ghana’s first licensing round will launch Q4 2018.

The survey objective is to image the basin architecture, define the limits of the various basins along the equatorial margin and identify petroleum systems offshore West Africa. It integrates available offshore well data to calibrate key stratigraphic horizons regionally and place this part of the margin in a larger (continental) context.

The uniform acquisition and processing of the new data provides a valuable calibration for AVO, phase rotation & amplitude balancing of existing datasets and for application of future technologies.

Acquisition parameters:

  • Streamer Length 10 km
  • No of Recording Channels 800
  • Group Interval 12.5 m
  • Shot Point Interval 50 m
  • Nominal Fold 100
  • Record Length 18 s
  • Sample Rate 2 ms
  • Source and Streamer Depth 10 / 15 m

Processing parameters:

PSTM and PSDM using the full integrated SPAN™ workflow with integration of gravity
data and well data if available for velocity model building and calibration.
PSDM imaging will be down to approximately 40 km or the equivalent depth indicated by a record length of 18 s.
