Norway: Searcher Seismic, Dolphin Complete Gulspurv 3D Survey

Searcher Seismic together with project partner Dolphin Geophysical have completed acquisition of the Gulspurv 3D high resolution seismic data.

The Fast Track Cube (FTC) preliminary processed data from the survey shows excellent resolution with good shallow structure illustrating the exciting new prospectivity in the current 22nd round bid blocks and is ready for delivery from the end of August 2012.

The Gulspurv 3D new acquisition comprises of 1,997 km2 of high resolution 3D seismic data over the highly prospective Bjørnøyarenna Fault complex.

The survey was acquired with a 2ms sample rate and a near offset nominal distance of 75m. 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 12.5m (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.

The onshore processing of the final 4ms volume will continue through refinement and migration until the final dataset is delivered in November 2012. The 2ms high fidelity data is available for reprocessing and focussed quantitative interpretation.
