Depth Imaging Unfolds Complex Geology and Impacts Reserves - the Q4 Story

P071 DEPTH IMAGING UNFOLDS COMPLEX GEOLOGY AND IMPACTS RESERVES – THE Q4 STORY M. KEMME 1 G. BROWN 2 N. VAN BUUREN 3 and M. GREENWOOD 4 Abstract 1 In a very complex structural area two recent successful exploration wells have been drilled. Because of the complex ray paths in the overburden seismic quality of the conventionally processed seismic time data was patchy and there were indications that the lateral positioning of the major structural elements was not always correct. Pre-stack depth migration produced a much clearer seismic data set showing a widening of the structure and a small but
