The shallow part of seismic deep offshore of Nigeria (sea bottom to Pliocene) is generally screened to appraise shallow hazards which could appear during drilling or on a geotechnical point of view. Also, thanks to the very good quality of the 3D high resolution seismic, these time sections are also studied with a morphological objective and reveal geological treasures as well on the level of turbidite architecture features, as on the deposit-remobilization processes.
This quick look study was performed on an area located on the eastern part of the Niger delta–Eastern Lobe (Fig. 1). The objectives were multiple:
To perform an inventory of the different turbidite systems in order to understand the stratigraphic link and the deposit process,
To provide sub-surface analogues in terms of morphology, size, and seismic response. These analogs are one of the tools currently used for exploration, appraisal, and also modeling. This approach is complementary with outcrop analogs.
To evaluate the seismic artifacts generated by the shallow series that could affect the visibility of the seismic in the reservoir objectives.
