Technical Abstract

Grane PRM: From Acquisition to Interpretation in Record Time

Back to Technical Content
By August 2014 a full Permanent Reservoir Monitoring system was installed at the Grane field; since going live, five PRM surveys have been acquired. This paper describes how a robust sequence has been designed and optimized, thanks to the successful collaboration between processing (CGG) and interpretation (Statoil) teams. The 4D products are available to the interpreters 8 to 10 days after the last shot. An example is presented, illustrating the value of fast delivery of fresh 4D PRM seismic data; we also discuss a 4D processing designed to address the different acquisition geometries between vintage OBC surveys and PRM surveys.
