TGS expands 2D seismic data collection in eastern Indonesia

TGS-Nopec, geophysical company listed on the Oslo Stock Exchange, has commenced a 2D multi-client seismic survey in offshore eastern Indonesia immediately north of the Sunrise-Troubadour gas fields and to the west of the Abadi gas field, the company said.

The 1,500 km survey, MHI 11, will infill a seismic survey previously acquired in 2007 and an extensive multibeam data set in the area.

The survey is supported by industry funding, and it supports the Indonesian governments overall objective to attract exploration, the company said.

The previously acquired seismic data in the area has revealed a series of undrilled fault blocks and horsts from the Permian up to the Base Tertiary levels. This project will provide a final detailed grid of data and assist with evaluating the Sahul Platform and Timor Trough area where data indicates an active petroleum system, it said.

TGS maintains the industry?s largest multi-client data library in Indonesia. Upon completion of the MHI 11 survey, the library will include 120,000 km of 2D seismic, 3,500 km2 of 3D seismic, 400,000 km of multibeam bathymetric data and 1,200 core samples covering over one million km2 of Indonesia?s deep water basins.

The seismic data is being acquired by the M/V Aquila Explorer. Data processing will be performed by TGS and available to clients in the fourth quarter this year.

The survey is supported by industry funding and also supports the Indonesian governments overall objective to attract exploration, the company said. (romel)
