NIGERIA: PGS Supports Nigeria Delta Mini Bid Round

The Nigerian Upstream Petroleum Regulatory Commission (NUPRC) have scheduled a pre-bid conference on 16 January 2023, after which interested companies will be invited to submit their pre-qualification applications by 31 Jan 2023.

Seven blocks are on offer, focused in the north-western Nigerian Offshore. Blocks PPL-300-DO, PPL-301-DO and PPL-302-DO are located in the Nigerian Transform Margin area. Blocks PPL-303-DO, PPL-304-DO, PPL-305-DO and PPL-306-DO are within the deepwater Niger Delta Basin.

PGS has assembled a data package to license over the blocks, comprised of ~10 000 sq. km of merged 3D seismic data. This is composed of various input surveys which have been matched, merged and re-binned onto a common grid resulting in a single, continuous volume of full-stack seismic data in the time domain.

This extensive seismic coverage allows for regional-scale understanding of prospectivity in and around the license round acreage. Enhanced datasets are also available to license as GeoStreamer PSTM and MegaSurveyPlus PSTM which have additional products such as angle stacks and gathers.

PGS Data Provides Better Geological Insight

The Niger Delta Basin is dominated by up to 12 km of Late Cretaceous to Quaternary aged clastics deposited in an upward coarsening regressive deltaic sequence. The main source rocks are Akata Formation marine shales and Lower Agbada Formation paralic shales. Proven reservoirs in the basin are dominated by unconsolidated sandstones of the Agbada Formation deposited as stacked turbidite channel and fan complexes.

Two main plays are proven in the Nigerian Transform Margin area; the syn-transform Lower Cretaceous and post-transform Upper Cretaceous. Cenomanian-Turonian marine shales provide an oil-prone source rock in the region, with potential reservoirs deposited as shallow and marginal marine sandstones in the Lower Cretaceous, and deep-marine sandstones in the Upper Cretaceous.

With the Petroleum Industry Act in place potential bidders benefit from a clear legislative backdrop from NUPRC as well as from a wealth of 3D seismic data from PGS.

MegaSurveyPlus full stack PSTM provides high-resolution imaging of structure related to the complex diapirism of the Akata Shale Formation.
