The Application of 4D Seismic in Niger Delta Basin: A Review

Abstract

Time-lapse seismic also known as 4D seismic is one of the advanced techniques employed in the oil and gas industry for petroleum production management and monitoring for over 20years. It involves carrying out two or more 3D seismic at different calendar times, before and after production over the same reservoir. We present advances in Time Lapse 3D seismic (also known as 4D seismic) and its application in the Niger Delta basin of Nigeria. Over the years, the technique has been used in Niger Delta to understand reservoir drainage performance, enable better well placement, identifying bypassed oil, detecting fluid communication, understanding of internal architecture of the reservoirs, and locating infill wells for future re-development. 4D seismic has demonstrated its potential and it is fast becoming a standard tool in the oil companies.
