Natuna Basin - Indonesia - 2010
High Definition MultiClient 3D data over the giant D-Alpha structure, offshore Indonesia
The survey was acquired in cooperation with MIGAS over the D-Alpha structure, a middle to late Miocene platform reef carbonate which lies approximately 200 km northeast of Natuna Island.
The D-Alpha structure has gas reserves of more than 200 Tcf attributed to it, although 70%+ is considered to be CO2. With such high CO2 it was deemed important for the safety and planning of development to have a high quality 3D image of the field, since a 1% error for engineering could be 2Tcf.
725 sq km of High Definition MultiClient 3D data over the giant D-Alpha gas field ensured that subtle faulting and internal features of the reef could be clearly imaged.
