Abstract

Existing seismic data and appraisal drilling in the lower Congo basin show evidence of significant sandstone reservoirs in the tertiary section, formed by deepwater turbidite flows. The challenge is to develop and manage these complex reservoirs. To delineate the reservoirs, it is important to identify the fine details of the geometry of the reservoir sands and locate the structural and stratigraphic trapping mechanisms. The cost of drilling development wells in this area and the complex nature of the reservoirs make reflection seismic data a cost-effective tool in reservoir management. Thickness resolution obtained from existing seismic data in this area is in the order of 19 m A new survey was acquired in 2003 in an effort to obtain higher resolution.<br><br>In this paper, we describe the planning, acquisition, and processing results of a high-resolution point-receiver seismic survey. The survey was acquired with the objectives of mapping the thin sand units associated with turbidite sand channels, to provide long offset data not present in the existing data and to assess the benefits of point-receiver acquisition. <br><br>Results indicate that the objectives of the project have been met through acquisition and high-fidelity processing of point-receiver seismic data. <br><br>
