PGS Commences Moray Firth Phase 2

Next week, PGS will start acquisition of the second of three new 3D GeoStreamer® surveys covering nearly 7 400 sq. km of the Moray Firth area of the North Sea. Phase 1 is now complete. Fast-track data for each phase will be available four months after final shot.

This prefunded MultiClient project promises to reveal a large swathe of the Moray Firth-Orcadian Basin area. Phase 1 covering the outer Moray Firth is now complete and processing is ongoing.

Phase 2 focuses on the inner area of the Moray Firth. This is less explored due to the challenging combination of shallow water, shallow sub-surface Chalk Grp and deep targets. The key imaging challenge of Moray Firth is the masking of deep structures by a combination of shallow water and complex shallow overburden.

High-density GeoStreamer data and modern imaging technology will address this, to improve the understanding of the source and the reservoir potential. 

Imaging all Recorded Wavefields

PGS' Complete Wavefield Imaging (CWI) workflow has a proven track record of solving the shallow to reveal the deep. CWI utilizes GeoStreamer dual-sensor technology to process and image all recorded wavefields. Using this technology we generate top-to-bottom high-quality datasets by utilizing not only reflections but also refractions (FWI) and multiples (SWIM). The process starts with state-of-the-art signal processing and results in accurate velocity models through full integrity imaging.

In addition to providing an excellent basis for exploration decisions, these three new Moray Firth datasets can be used as a baseline survey for future 4D studies, making this a cost-effective solution for exploration, evaluation, field development and production monitoring.

This is PGS’ tenth consecutive year of safe and reliable GeoStreamer acquisition in Northern Europe. This new high-density GeoStreamer survey in Moray Firth area that will be important for upcoming rounds in the UK covering both mature and frontier areas.
