Salamander Energy plc, an independent upstream oil and gas exploration and production company focussed on South East Asia, reports the successful appraisal of the Tutung gas-condensate discovery in its operated Bontang PSC, East Kalimantan, Indonesia.The Tutung Alpha-1 well was drilled to a total depth of 3,250 metres sub-sea and the found multiple gas and condensate bearing sandstones between 2,990 metres and 3,120 metres sub sea in the target Middle Miocene Pulubalang Formation. A full suite of logs have been run and a comprehensive programme of both pressure testing and gas and fluid sampling has been carried out.
An initial analysis of the acquired data indicates the presence of good quality, multiple stacked channel sandstone reservoirs with a net pay thickness of at least 16 metres and a potential column height in excess of 60 metres. The original discovery well, Tutung-1, flow tested at 10 million standard cubic feet of gas and 613 barrels of condensate per day from a single channel sand.
The well has been suspended as a future producer. Salamander has an option to return and further appraise the Tutung discovery using the Ensco-1 barge mounted rig once it has completed the appraisal drilling on the Gurame discovery in the Seruway PSC, in which Salamander will have a 22.5% interest on completion of its proposed acquisition of GFI Oil and Gas.
