PGS to Cover Moray Firth in 2018

In May 2018, PGS will start acquisition of three new 3D GeoStreamer® surveys covering nearly 7 400 sq. km of the Moray Firth area of the North Sea, to be completed in October 2018. Fast-track data will be available four months after the final shot.

Moray Firth UK North Sea

This prefunded MultiClient project promises to reveal a large swathe of the Moray Firth-Orcadian Basin area.

Primary targets in the prolific outer area are the proven Upper Jurassic and Lower Cretaceous plays. The inner area is less explored due to the combination of shallow water, shallow sub-surface Chalk Grp and deep targets.

The new high-density GeoStreamer data and the most up to date processing technology will be used to improve the understanding of both source and reservoir potential. Possible plays vary from a fractured basement to shallower Cretaceous targets.

The key imaging challenge of Moray Firth is the masking of deep structures by a combination of shallow water and complex shallow overburden.

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 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 our 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.
