KrisEnergy has spudded the Tayum-1 exploration well in the Kutai PSC, offshore East Kalimantan, Indonesia, its partner Salamander Energy (23.4%) announced on 3 June 2013.
The Tayum well is being drilled using the Randolph Yost jackup rig to 2563m total vertical depth subsea and is targeting multiple stacked deltaic sandstone reservoirs of Upper Miocene age.
Tayum-1 is located between two gas discovery wells, Mangkok-1 ST4 drilled in 2001, which is 4 km north northeast, and the 2010 Dambus-1 well, 9 km north northwest.
The mean gross pre-drill estimate of prospective recoverable resource of Tayum is about 80 Bcf, with an upside (P10) case of 182 Bcf.
The operator is carrying about 73 Bcf (2C) of contingent resource, with an upside case of 115 Bcf (3C), on the block and success at Tayum could result in a commercial development.
The Kutai PSC comprises one onshore and three offshore areas covering a combined 2832 sq km in the Mahakam River delta in East Kalimantan.
KrisEnergy holds a 54.6% operated working interest in the Kutai PSC. Its partners include Salamander Energy and Orchid Kutai (22%).
