Airborne gravity survey launched for southern Gulf of Mexico

CGG will complete as many as five additional areas in the southern Gulf of Mexico through 2018. The program will total 200,000 line-km of multiclient airborne gravity and magnetic survey. The company completed its first area, AOI 1, in December 2016 and has processed and interpreted about 38,000 line-km over the gulf’s Perdido foldbelt.

CGG said the newly acquired Perdido foldbelt data correlates discoveries along the flanks of basement topography. The data and interpretation will help operators map the often-difficult-to-image crystalline basement to construct an improved Earth model. The airborne survey also collected continuous data through the transition zone from marine environment to onshore.
