CGG Announces Largest Ever Seabed Survey

French geoscience company CGG said it will perform its largest seabed survey to date in the UK Central North Sea.Prefunded in part by BP, the multi-client ocean-bottom node (OBN) seismic survey has already received significant industry interest, CGG said. Operations are scheduled to begin in early 2020, with first results targeted for the first quarter of 2021. CGG said it aims to acquire over 2,000 square kilometers of OBN data in the first phase of this multi-year program."In the Central North Sea, where complex salt diapirism has created significant challenges to imaging deeper reservoir

Mooring Change-out for the Alba FSU

ChainCo’s quayside yard in Montrose, UK.The project was completed on schedule within all design tolerances and with no disruption to the FSU operation throughout.Discovered in 1984 in Block 16/26, the Alba heavy oil field field lies about 210 kilometers northeast of Aberdeen, in the UK Central North Sea. First oil was achieved in January 1994.In addition to the FSU (the first purpose-built for the UK sector of the North Sea), field facilities include a fixed steel platform, the Alba Northern Platform, and the Alba Extreme South subsea production center added in 2001.Alba crude oil is offloaded

Premier Oil Testing PB3 PowerBuoy in the North Sea

US-based ocean energy solutions company Ocean Power Technologies (OPT) said it has deployed a PB3 PowerBuoy to serve as an autonomous intelligent platform to provide communications and remote monitoring services for its customer Premier Oil at the Huntington field in the UK sector of the central North Sea.During the deployment, Premier will demonstrate the PB3 PowerBuoy capabilities, its ability to monitor the local environment and alert ships of the field’s safety zone as a potential solution to help with their future decommissioning related operations, OPT said.This deployment begins

of collaborative working methods, we can bring more efficient, repeatable solutions to our clients that increase value, reduce engineering interfaces and time to market.”Seagull is a high-pressure, high-temperature (HPHT) development located in approximately 90 meters water depth in the Central North Sea on UK licence P1622 Block 22/29C, 17 kilometers south of the BP-operated ETAP (Eastern Trough Area Project) Central Processing Facility (CPF). Comprising four subsea production wells, a new 5 kilometer pipe-in-pipe production line and a 17 kilometer control umbilical, Seagull outputs will travel

with its global network of facilities, personnel and market positioning, can provide significant value to our customers,” said George H. Kirby, President and Chief Executive Officer of OPT.The companies are currently collaborating on an Exclusion Zone Monitoring project for Premier Oil in the Central North Sea. The project will include the deployment of OPT’s PowerBuoy system, and surveillance and monitoring technology and a turnkey mooring and deployment solution provided respectively by Acteon operating companies Pulse Structural Monitoring and InterMoor.Tim Martin, Vice President, Decommissioning

results. A southern extension of 8,000 km² is currently being acquired, which will be processed through the same sequence and seamlessly merged.The Q modeling and imaging techniques are widely applicable elsewhere in the world. For example, CGG’s 35,000 km² Cornerstone survey in the Central North Sea is currently being processed through a similar sequence, with impressive high-resolution images of the Forties channels already having been achieved.Further research is ongoing, testing the benefits of Q least-squares migration algorithms. Least-squares migration inherently favors amplification
