The Simenggaris Block comprises 1,351 sq.km and is located onshore in the Tarakan Basin, East Kalimantan. Oil and gas production is well established in the Tarakan basin, with between 400-500 million barrels of oil equivalent being found in the shelf area. Recent significant oil discoveries have been made in the deepwater foldbelt outboard of the Bangkadulis halfgraben, east of the Simenggaris block location.
Within the original license area, some 20 exploration wells have been drilled, resulting in seven discoveries and two commercial oil fields. Other nearby oil and gas production includes the Tarakan and Bunyu Island fields. The block contains numerous gas, condensate and oil prospects and leads, seen as structural traps with Middle Miocene sandstone reservoirs.
South Sembakung Discovery
A plan of development for the South Sembakung gas-condensate discovery was approved by BP Migas, the Indonesian regulator, in 2008. Gas will be sent via pipeline to the Bunyu Island Methanol Plant. A GSA has been signed for 20 MMscfd over an 11 year period at $3/mcf with production expected to commence late in 2011.
