Abstract
The lithofacies and environments of deposition of the EMK field, in parts of the deepwater zone of Niger Delta Basin, have been carried out. Geophysical well logs from two deep oil wells were used. Shale and sand were identified in the gamma ray logs. The shale lithology is more dominant than the sand and this was interpreted as the marine Akata Formation. Four sand bodies were identified and correlated across the wells. The shapes of the gamma ray signatures are funnel, bell and cylindrical. Prograding, retrograding and aggradational parasequences were identified from the stacking patterns of the gamma ray curves. The environments of deposition delineated for the study area are slope fans and basin floor fans.
Highlights
The study area EMK field is part of the deepwater depositional belt in the Niger Delta, which extends from isobaths contour of 2000 to 4000 m
The log motifs of prograding, retrograding and aggrading features were identified in the study area and used to characterize the depositional environment
3050 3100 3150 depositional environments were recognized by vertical grain size, log shapes and morphology
Summary
The study area EMK field is part of the deepwater depositional belt in the Niger Delta, which extends from isobaths contour of 2000 to 4000 m. The area is about 120 km off the coast of the western Niger Delta region and within the fold-thrust province in the continental slope and abyssal plain (Corredor et al, 2005). This area is one of the most important exploration provinces in the world and most of the deepwater hydrocarbon reservoirs are discovered within the Turbidites (Vail, 1987; Weimer and Pettinghill, 2007). Turbidite deposits are graded and usually show a fining upward sequence (Bouma, 1962; Bouma et al, 1985; Lowe, 1982)
