Abstract:

The Iroko-Mokoko-Abana fields (hereto referred as IMA) are located in the Rio-Del Reyâ??s basin of the Niger Delta within an area of 24,108 acres (97.56 square kilometers); in which oil and gas accumulations are associated with multiple stacked structural traps formed in response to shale diapiric activity and the formation of shale ridges in a deltaic environment, forming a highly structured and complex hydrocarbon traps environment. The structural style of these fields was identified using 3D seismic volume interpretation, where the seismic was combined with wells data. The structural interpretation of six key seismic cross well sections were firstly done to confirm the structural and sedimentary framework, then three key regional horizons of different depth levels were interpreted with their seismic attributes been extracted, and finally the depth conversion of the interpreted time maps were converted using a 2nd polynomial T-D function derived from well information. The integrated results demonstrate that there are 13 big Synsedimentary growth faults related to four shale diapirs of the Akata shale formation; these diapirs and their growth faults have acted as a positive element to produce faulted structures and have divided the IMA into 13 micro-faulted-structural blocks. Many additional potential hydrocarbon accumulations are located within these faulted structural blocks.
