PERTH, Australia - TGS has commenced a multi-phase reprocessing program of 2D seismic data taken in the Makassar Strait, Indonesia. The first phase consists of 2,700 km (1,678 mi) of seismic data in the Northern Mahakam Delta.

The data will be reprocessed with customized techniques to enhance imaging of the main structures and reservoir targets in the basin. The reprocessed data is intended to enhance definition of direct hydrocarbon ondicators and amplitude versus offset anomalies associated with turbidite reservoirs seen on the original 2D seismic data.

Data from this initial phase of reprocessing will be available for clients in 3Q 2011. This project is supported by industry funding.

The original and reprocessed data support the exploration potential of the deepwater area of the Mahakam Delta. Interpretation of the seismic data since 2001 has demonstrated n prospectivity in the basin, resulting in the award of exploration acreage and the drilling of several exploration wells. Partial relinquishments of the blocks has created opportunities for new exploration in the area.
