Lithological Characterization Using Parasequence Set for Depositional Environment of KD Field Shallow Offshore Niger Delta Basin

Abstract

Aims: The purpose of this study is to delineate the environment of deposition from gamma ray log using parasequence set, for the well 01,02 and 03 within KD field for hyrdrocarbon prospect. Study Design: The result of the lithostratigraphic analysis carried out on three wells from the KB field are presented and discussed. Place: The study was carried out in the shallow offshore Southern Niger Delta, Nigeria from wells 01, 02 and 03 of KD Field. Methodology: Gamma ray logs were subjected to para sequence set before using and log motif Interpretation were referred to know the depositional environment of the KD field shallow offshore Niger Delta. The lithologic descriptions were complemented using logs analyses. Results: Based on their lithologic properties, investigation of the three wells were based on reservoir A, B, and C in the study area. The depositional environment falls within the nearshore face to intermediate offshore part of the Delta. The Unit is estimated to be 176m thick and is characterized by sands and a sand-shale layer alternation. In this investigation, only the Agbada Formation were encountered, it is characterized by Aggrading, Prograding and Retrogradational parasequence set.
