Abstract
Block 32, deep offshore Angola, is located in an area of the Lower Congo Basin heavily affected by the salt tectonism: salt domes or canopies are extensive. As a consequence having a good seismic image is critical in terms of exploration but also development of discoveries. Over the past decade the focus has moved towards the sub-salt play and the use of conventional seismic has reached its limits. As a consequence, Total E&P Angola embarked in 2012 in a project to address complex subsalt challenges in the Central North East part of the Block 32, using innovative technologies: from survey design, to acquisition, processing and imaging. The objective was to deliver interpreters a state-of-the-art and fit for purpose solution in a timely and cost-effective manner. This project is known as the Block 32 CNE Bi WATS. This abstract aims to give a full overview of the project, from its genesis to its execution, and finally present some of the results
