Technical Paper: Multimeasurement Streamer Acquisition for Reservoir Development - A Case Study from Offshore West Africa

Abstract

A towed-streamer seismic survey was acquired offshore West Africa using a multimeasurement acquisition system. The objective of the new 3D seismic survey was to acquire high-quality, high-resolution 3D seismic data to improve confidence in siting appraisal and development wells above that given by existing legacy 2D data. Analysis and preliminary interpretation of the processed data volumes show that the data set achieved the characteristics of broadband seismic data required for detailed structural and stratigraphic interpretation, with receiver-side deghosting benefiting from a flat, deep streamer tow configuration and contribution from velocity data - derived from the accelerometer measurements for frequencies below 10Hz.
