MAKASSAR AND TARAKANMULTI-CLIENT 2D SEISMIC LIBRARY

Between 1999 and 2004, over 26,000 km of multi-client 2D seismic survey data was acquired by TGS, comprising of the MDD99, CM01, CM02 and CM04 surveys. These data sets were the first regional 2D multi-client seismic to be acquired in the Makassar Strait and to identify the West Sulawesi fold belt and deep water Mahakam Delta petroleum system. As part of the 2007 Indo Deep (IDD) project, TGS acquired over 40,000 km2 of multibeam data and 228 sediment cores with subsequent 613 geochemical and 14 heat flow results in order to assist exploration groups in Indonesia.

From 2010 until early 2011, TGS acquired its first MC3D survey in Indonesia located in the Tarakan Basin offshore East Kalimantan. The survey consisted of two phases which combined TBN10 and TBB11 covering nearly 3,500 km². The data assists in improving the understanding of the complex structural and stratigraphic setting of this important oil and gas province and particularly in prospect delineation and well planning. Anadarko’s discovery well, Badik-1, is covered by the TBN10 phase of the survey.
