PGS Completes MultiClient 3D Seismic Acquisition Offshore Republic of Guinea

Thursday 16 May 2019

PGS’ latest MultiClient 3D GeoStreamer acquisition covering blocks A4 and A5 of the Republic of Guinea was completed on 8th May 2019. Fast-track processing is ongoing.

The Guinea MC3D survey is PGS’ first MultiClient project in collaboration with the Republic of Guinea and marks the start of a series of planned acquisitions.

The Ramform Titan-Class seismic survey vessel commenced operations in mid-February and acquired 3D seismic data for 84 successive days.

Survey Summary

- Vessel: Ramform Atlas

- Streamer/ Source Technology: GeoStreamer

- Survey Area: 7 900 sq. km

- Water Depth: 60-4500 m

Acquisition Parameters

- Number of streamers: 12

- Streamer Length: 8025 m

- Streamer separation: 150 m

The competent and well-managed PGS crews delivered excellent HSEQ performance, in line with our corporate commitment. The speed of operation, together with a highly effective seismic spread, reduced overall survey duration, maximizing efficiency and minimizing environmental impact. Online barnacle scraping lessened noise and improved data quality while reducing exposure to HSE risks. Evaluation of the acquired separated-wavefield data (P-UP) confirms the high standards achieved.

PGS brings GeoStreamer technology with a true broadband imaging solution to the Republic of Guinea. Broader bandwidth and rich low-frequency content provide clearer reservoir details in all play types, with reduced sidelobe artifacts.

The project includes the acquisition and processing of seismic, gravity and magnetic data over open acreages. Commercial, strategic and technical benefits are available now to early participants in the survey.
