Debris flow outrunner blocks, glide tracks, and pressure ridges identified on the Nigerian continental slope using 3-D seismic coherency

Abstract

The Nigerian continental slope, approximately 100 km offshore from the northwestern flank of the Niger Delta, is in the earliest phases of exploration; therefore, no well control is available to aid in the interpretation of the paleodepositional setting of this area. However, a 500-km2 portion of the area is covered by a 3-D seismic survey, and in the absence of well control, 3-D seismic coherency images have played an important role in the interpretation and confirmation of the paleoenvironment and depositional systems of the area.
