Pre-Stack Time and Depth Migration, Onshore Morocco

12th June 2018

Shearwater GeoServices has delivered a 3D Pre-Stack Time and Depth Migration product for Sound Energy Plc, from onshore Morocco.

Since expanding the processing and imaging capabilities into land seismic in 2016, Shearwater’s experienced team of land geophysicists has reprocessed over 500 of 3D land seismic through PreSTM and PreSDM sequences, applying the latest onshore technologies including advanced statics, 5D Regularisation, tomographic update for P-wave velocity and Diving-Wave Tomography to supply a modern, high quality seismic volume to Sound Energy.

In addition, and in parallel to this, Shearwater has been reprocessing ~2,000 km of legacy 2D seismic and ~2,000 km of newly acquired 2D seismic to provide improved subsurface imaging over key target areas for Sound Energy.

Dr John Argent, Exploration Manager, Sound Energy Plc commented: “The collaborative working relationship between ourselves and the deep technical expertise brought by Shearwater led to demonstrably improved imaging of our vintage seismic database, much of which was originally acquired in 1970s and 80s.  These new images have already increased our understanding of the subsurface across our Eastern Morocco licences and allowed us to better define targets for our planned 2018 drilling campaign”

Simon Telfer VP Processing & Imaging, Shearwater GeoServices commented: “Our Land Processing & Imaging is a key part of our services and working closely with Sound Energy to deliver both the 3D and 2D seismic has clearly demonstrated our capabilities.  By combining our own easy to use, high-end processing software with an experienced team of land Geophysicists and a culture of excellence we were able to provide Sound Energy with high quality seismic data to help improve their decision making prior to drilling.”
