FRENCH survey group CGG has been appointed by InterOil to conduct both a land seismic and an airborne gravity survey over its Papua New Guinean acreage, in order to assess its hydrocarbon potential.

CGG’s airborne will conduct an airborne gravity gradiometer (AGG) to acquire 11,000 line kilometres of high-resolution data with fixed-wing aircraft, as well as 25,700 line kilometres using rotary-wing aircraft, better suited to acquiring high-resolution measurements in the rugged terrain.

The 2D conventional land seismic award comprises a 465 kilometre survey in InterOil’s southern PPL 474 and PPL 476 permits (the Murua survey).

It may also include additional coverage totalling over 200 kilometres to the north over their Triceratops and Raptor discoveries.

CGG will deploy 2,100 Sercel Unite cable-free channels and autonomous seismic source technology during the two-part survey, which it said is due to end in August 2015.

The land seismic data will be processed by CGG at its Bangkok imaging centre.

CGG chief executive Jean-Georges Malcor said his company had developed a long-term partnership with InterOil in the Asia Pacific region over the last seven years.

“The awards also recognise both our ability to supply a fully integrated exploration solution and our capability to tightly integrate the interpretation using both the airborne geophysics and the land seismic data into a “basin in a box” multi-physics solution which will be highly beneficial to InterOil,” he said.

“They are an excellent example of how CGG’s unique range of fully integrated products and services can successfully come into play and bring significant added value to our clients’ exploration challenges.”
