PGS supports Nigerian Mini Bid Round with 3D coverage over seven blocks on offer
PGS, a global geophysical company that gathers offshore survey data and uses vast cloud compute to image the earth, announced it will support the recently announced Nigeria 2022 Mini Bid Round with an excellent range of 3D coverage over the seven blocks on offer.
The Nigerian Upstream Petroleum Regulatory Commission (NUPRC) has scheduled a pre-bid conference 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.
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.
