Searcher Seismic Pty Ltd in conjunction with Dolphin Geophysical announced the successful completion of acquisition for the Gulspurv 3D Seismic Survey. The survey comprises 771 square miles (1,997 square kilometers) high resolution 3D non-exclusive seismic data.
The survey overlies the highly prospective Bjørnøyarenna Fault Complex and is focused for the 22nd Licensing Round in the Barents Sea. The Gulspurv 3D is located 19 miles (30 kilometers) north of the recent Skrugard and Havis oil discoveries (500 MMbbl + recoverable reserves).
The survey was acquired with a 2ms sample rate and a near offset nominal distance of 246 feet (75 meters). Maximum shallow fold was achieved with a focussed source effort of a smaller volume (1,310 cu) high frequency source signature and shot point interval of 41 feet or 12.5 meters (flip-flop) to better preserve the shallow structural content in the data. The processing workflow is based on Searcher's successful high resolution 2D dataset from the Bjørnøya Basin North dataset acquired in 2011, and is tailored to maintain the high frequency content with the latest demultiple algorithms being employed and using modern interpolation and transforms.
The dataset has been processed as a 4ms volume to enable the fast track cube to be available at the end of August to allow interpretation prior to the closure of the 22nd Licensing Round evaluations.
