The offshore Nigeria shelf is West Africa's most prolific hydrocarbon province, with multiple billion barrel discoveries and decades of successful production. TGS, along with our joint venture partner PetroData, is committed to providing high quality data to assist in exploration in the deepwater Nigeria region.

TGS-PD data available for offshore Nigeria consists of:

  • 17,874 km NGRE19 2D seismic - formerly named the VERNG9899 survey, TGS' reprocessing project is currently in progress (view map)
  • 2,048 km NG02 2D seismic (view map)

Deepwater Potential

With significantly improved imaging of more than 17,000 km of recently reprocessed 2D seismic offshore Nigeria, TGS-PD data will enable a better understanding of the petroleum system of the deepwater offshore area. Our new depth imaging creates more accurate dip and realistic volume interpretation of features of interest. The potential for new license rounds over the deepwater open blocks, in conjunction with lower risk petroleum play concepts, could once again establish Nigeria as West Africa’s flagship country for exploration.

More than ten currently producing fields in water depths of 1,000 m to 3,000 m confirm source rock presence and maturity in the deepwater region offshore Nigeria. These seem to not only prove that the Akata Shale formation can be mature for oil further outboard than the shelf, but also that there are feasible migration paths and trap charge scenarios in the distal part of the delta lobes. This makes prospects further outboard viable, such as those identified in the outer fold and thrust belt. Structural analyses on the fault and thrust patterns and detachment mechanisms of the margin slope show that there are various viable set-ups of charging several folds and thrusts along the slope. The geometry and timing of the toe thrust formation which detached on a most likely over-pressured regional shale formation allow substantial volumes to be charged downdip from the known discoveries and production locations.  

New Technology Approach

As a next step in the deepwater exploration cycle, the de-risking of the source kitchen maturation and hydrocarbon migration paths is crucial. The seismic reflection imaging quality after Clari-Fi™ broadband reprocessing enables TGS-PD to consider new technologies such as Multi-beam and Seafloor Sampling (MB&SS) that provide geo-chemical data to de-risk plays by linking the mapped structures and modeled maturation scenarios for hydrocarbon sources sampled.
