Harbour Energy is gearing up for further exploration and appraisal on its ultra-deepwater Andaman II production sharing contract offshore Aceh, Indonesia, with the aim of adding to the 1 trillion cubic feet-plus of gas it discovered last year with its Timpan wildcat.

While Timpan-1 was seen as low risk, by wildcat standards, Harbour believes that its upcoming wells are even more likely to deliver given that Timpan has de-risked the Bampo play, which it reckons has between 13 Tcf and 15 Tcf of recoverable gas across the play.
