Reservoir Structural and Stratigraphical Evaluation of Sapele Deep Field, Niger Delta, Southern Nigeria.

Abstract

— Throughout the course of a field's existence, the oil and gas industry has not been very good at determining and forecasting how the stratigraphical and structural makeup of reservoirs will affect fluid flow. With harder-to-find reserves and growing development costs, it is critical to have a comprehensive plan in place to identify and reduce risks and uncertainties related to the stratigraphical and structural framework of reservoirs. Improving predictive capability is therefore the main task of our day. The research area's outlined strata thickens from north to south. On the other hand, the research area's considerable fault density is revealed by the structural interpretation. There is a noticeable throw to these faults, which may provide a route for the migration and deposit of hydrocarbons. Anticlines, which are important components of the majority of the Niger Delta's massive oil fields and have the potential to have several pay horizons, are typical structural types. The two defined horizons in the research region contain Sweet Spots (Bright spots), according to the Root-Mean Square Amplitude map analysis. 3D seismic cube and well log data were used to assess the research area's reservoir structural and stratigraphical framework. The study region is located between 50 33' 42.22" E and 50 53' 54.43" N.
