Eni has announced that its exploration well, Ken Bau-2X, located in Block 114, Song Hong Basin, offshore Vietnam, has confirmed a significant hydrocarbon accumulation on the Ken Bau discovery, further expanding its potential.

Ken Bau 2X was drilled 2 km apart from the discovery well in 95 m of water depth till a total depth of 3658 m below sea level and encountered a pay in excess of 110 m in several intervals of Miocene sandstones interbedded with shale.

Two mini drill stem tests (DST) were conducted, coupled with an extensive data acquisition campaign comprising fluid sampling. Preliminary estimates of Ken Bau accumulation provide a range between 7 and 9 trillion ft3 of raw gas in place with 400 – 500 million bbl of associated condensates. The well will now be plugged and abandoned.

Eni Vietnam is the operator of Block 114 with a 50% share; Essar E&P holds the remaining 50%. Eni Vietnam with its partner is currently planning additional drilling and testing on the Ken Bau discovery, coupled with new drilling and seismic activity in the Song Hong Basin, where Eni operates with a 100% share in the neighbouring Block 116.
