CGG is acquiring the first-ever multi-client airborne gravity and magnetic survey of the highly prospective onshore Congo Cuvette Basin in the Republic of Congo.
The Congo Cuvette basin is a large, underexplored onshore sedimentary basin in a logistically challenging area for resource exploration, said CGG. A specially modified aircraft equipped with CGG’s proprietary Full Spectrum Falcon airborne technology will simultaneously collect the gravity gradient, gravity, and magnetic data, for interpretation by CGG’s experts based in Perth, Australia.
The goals of the survey are to understand the sedimentary thickness of the Cuvette, and identify prospective structures using the low-noise Full Spectrum Falcon data.
It is estimated that the Cuvette could contain sediments up to 9-km thick, but with no modern data collected in the basin this will need to be verified. Geophysical data in the basin to date consists of 2D seismic data acquired mostly along the Congo River in the 1950s and 1970s as well as an airborne gravity and magnetic survey in the 1980s.
Greg Paleolog, senior vice-president, multi-physics, CGG, said: ‘The Cuvette Basin could be considered one of the last provinces in Africa to potentially hold giant to supergiant oil and gas accumulations.’
