CGG has been awarded both a land seismic and an airborne gravity survey by InterOil Corp. to assess the hydrocarbon potential of its acreage in Papua New Guinea, the company said in a press release.

CGG’s airborne group is to conduct a large FALCON airborne gravity gradiometer survey to acquire 11,000 line km (6,835 miles) of high-resolution data with fixed-wing aircraft and 25,700 line km (15,970 miles) using rotary-wing aircraft, better suited to acquiring high-resolution measurements in the rugged terrain.

The 2-D conventional land seismic award comprises a 465-km (290-mile) survey in InterOil’s southern PPL474 and 476 permits (the Murua survey) and may include additional coverage totaling in excess of 200 km (124 miles) to the north over their Triceratops and Raptor discoveries. To ensure robust operations in challenging operating conditions CGG will deploy 2,100 Sercel UNITE cable-free channels and autonomous seismic source technology during the two-part survey, which is due to start in January and end in August 2015.

CGG’s Bangkok imaging center will process the land seismic data as part of the integrated service CGG is offering InterOil.
