PARIS – CGG has delivered the Fast Trax Reverse Time Migration (RTM) data from its Encontrado multiclientmega-merge project covering the Perdido fold belt on time to the industry and the Comisión Nacional de Hidrocarburos (CNH) ahead of Mexico’s December Licensing Round.
The Fast Trax results are available now for license on a non-exclusive basis, with final imaging datasets expected in the summer of 2017, the company said.
The Encontrado reprocessing project is a merge of over 38,000 sq km (14,671 sq mi) of wide-azimuth data from more than nine previously acquired and processed surveys, covering some of the most prospective areas of the Gulf of Mexico, including the Great White and Trion discovery to the north and Corfu and Ixcuta further south. More than 35,000 sq km (13,513 sq mi) of the data is in the Mexican sector of the Gulf of Mexico. CGG said that the data is being processed through a sequence including bandwidth extension and 3D deghosting, 3D SRME, and advanced imaging using TTI RTM and Kirchhoff migrations. Tomography and Full-Waveform Inversion are being used to enhance the velocity model.
