The Brunei offshore shallow water acreage that Shell Deepwater Borneo (SDB) operates provides both opportunities and exploration challenges. In order to identify material prospects and to secure future exploration success, legacy play and prospectivity concepts needed to be updated: large conventional, shallow traps and obvious hydrocarbon-induced amplitude-supported prospects are absent - instead, the search is on for deeper and not directly amplitude supported prospects, which demands application of innovative exploration workflows. A key enabler in exploring these blocks is by introducing new technologies, in particular, the latest seismic technology in the form of 3D Broadband seismic which has been acquired and processed in 2013 & 2014. An integrated approach to reservoir prediction by utilizing this new broadband seismic data, a reservoir prediction workflow combined with cutting-edge visualization techniques will be presented in this paper. The broadband data was pre-stack depth migrated and subsequently interpreted by leveraging multi-disciplinary integration of the geophysical with geological and petrophysical data. Through the use of advanced visualization technologies, this data now crucially supports SDB’s exploration campaign. For a prospect example, we showcase the successful application of a reservoir prediction workflow that utilizes the new broadband seismic data and a reservoir prediction workflow that consists of four major steps: 1. rock and fluid property analysis, 2. elastic impedance inversion, 3. body-checking for litho-fluid discrimination, and 4. cutting-edge visualization/sculpting techniques.
