BGP Completes 3D Seismic Acquisition Offshore Gabon for Perenco
China's BGP Inc. reported Wednesday that its seismic vessel BGP Pioneer successfully completed Perenco Oil & Gas Gabon 3D seismic acquisition project of approximately 579 square miles (1,500 square kilometers) offshore Gabon. The project was challenging as it included undershoot operations between platforms, and was to be run in water depth varying between 49 to 180 feet (15 to 55 meters) of water depth.
Overall 3 major seismic vessels - BGP Pioneer, Explorer and Prospector - were involved at different times in the area of survey together with the BGP Supply 2 boat and other chase boats - MV Maria and Admiraal de Ruiter.
The shallow survey area (approximately 50 square miles or 130 square kilometers) of 49 to 65 feet (15 to 20 meters) bathymetry depth contour, required a smaller towed array (1.8 x 3.7 miles or 3 x 6 kilometers). This part of the survey, located in shallow waters, was completed in 15 days using BGP Explorer.
The larger survey area (around 529 square miles or 1,370 square kilometers) of water depth between 49 to 180 feet (20 to 55 meters) was acquired by BGP Pioneer, trailing an array of 3.7 x 3.7 mile (6 x 6 kilometer) spread. Undershoot operations and close approaches to obstructions were run with BGP Prospector as source vessel, and BGP Pioneer as recording vessel.
BGP Pioneer 3D shooting operations in the survey area faced many issues due to the presence of production oil platforms, heavy fishing activities (numerous Fishing Aggregating Devices – FAD were removed from waters), drilling offshore activities, protected marine area, protected marine mammal species, prevailing currents, engine issues etc. All these factors could have cause excessive delays. Nevertheless, undershooting job was completed in good time. Acquisition within the larger survey area was achieved after 78 days of focused hard work.
The excellent coordination and organization of the operations allowed BGP Pioneer to complete the whole survey on time with excellent coverage and great quality of data.
At the end of survey, BGP Pioneer ported call in the city of Port-Gentil. BGP Marine team together with the Exploration department of Perenco Oil & Gas Gabon, invited a total of 13 kids from local orphanage to visit the BGP Pioneer. The kids were showed the latest seismic gears onto the acquisition vessel. At the end of the visit, children received school bags, and a donation from the Captain of the BGP Pioneer.
