CGG releases major offshore PH seismic data study results

By on July 7, 2017

International seismic specialist CGG has announced that the final geoscience data for its Carabao multi-client study, acquired offshore the Philippines, are now ready for delivery.

The study integrates over 8500 km of new broadband prestack time-migrated 2D BroadSeis data and complementary marine gravity and magnetic data acquired with the seismic.

The BroadSeis data were acquired from May to August 2016 and processed in CGG’s Singapore imaging center, using the latest broadband imaging technology.

The survey connects diverse sedimentary basins across the Philippines from West Palawan (the only currently-producing basin in the country), across the Sulu Sea, to the Philippines Mobile Belt.

The survey area is characterized by extensional and compressional tectonic elements and displays positive indica.

The marine gravity and magnetic data were acquired and processed in parallel with the seismic survey by CGG Multi-Physics. This potential field data will aid interpretation by providing an overview of the basement-controlled structural trends in the area. By considering different physical properties

of the same geological section, the potential field data can also discriminate between volcanics, intrusives, carbonates and salt, where present, further de-risking and enhancing interpretation of the seismic data.

Luc Schlumberger, CGG Executive Vice President Multi-Client & New Ventures, said the Carabao regional study is part of CGG’s strategy to provide greater understanding of prospective regions by combining the company’s geological expertise with state-of-the-art geophysical technology in integrated geoscience programs.

“This multi-client seismic and gravmag program will provide new insight into this underexplored region,” Mr Schlumberger said.

“We are confident it will underpin future exploration success by enabling petroleum explorers to better understand the geological history of this complex area and its petroleum potential.” PRJ
