Fluid Flow Structures of the Miocene-Holocene Succession, Western Slope, Niger Delta

The analysis of a 3D seismic data from western slope of the Niger Delta reveals several fluid flow structures in the Miocene to Holocene stratigraphic succession. These structures, imaged on attribute maps and seismic sections, include seafloor features such as mud volcanoes and their collapse structures as well as pockmarks. Others include buried seafloor mounds; amplitude anomalies as well as bottom-simulating reflectors (BSRs). The fluid flow activity in study area appears to be controlled mainly by mobile shale tectonics and dewatering of mini-basin sediments. These structures can be used to investigate fluid flow history, timing and migration, particularly with regards to hydrocarbons.
