CGG has been awarded an extension to a major 3-D seismic survey it completed on the Caribbean coast offshore Colombia in late 2015, the company said in a news release.

The new survey follows on from the original survey that covered more than 16,000 sq km over portions of the Col-1 and Col-2 blocks offshore Colombia. The extension is expected to start in February 2016, CGG said in the release.

The additional data will be processed in CGG’s Houston subsurface imaging center, the release said.
