Empyrean Energy Plc has provided an operational update in relation to the drilling campaign in the Duyung PSC in the West Natuna Basin, offshore Indonesia, in which Empyrean holds an 8.5% interest.

The Tambak-2 well has been drilled to a TD of 1650 ft TVDSS. The coring programme, wireline logging and pressure surveys have now been completed and confirm the well as a successful appraisal of the Mako gas field.

As previously reported, the Tambak-2 well spudded on 4 October and is designed as an appraisal of the southern area of the Mako gas field. An independent review by Gaffney Cline & Associates had previously ascribed gross 2C resources of 276 billion ft3 (48.78 million boe) of recoverable dry gas in the Mako field with gross 3C resources of 392 billion ft3 (69.3 million boe) representing additional field upside.

The next step in the campaign is an extensive Drill Stem Test (DST) programme, which will take place over the coming days and the market will be updated with results of this as appropriate.

Tom Kelly, Empyrean CEO commented: “The fact that we have confirmed good quality reservoir at a 13.5km step out from the Mako South-1 discovery well is an excellent step forward for this project. The wireline logs confirm excellent porosity and permeability and we look forward to the flow testing programme to commence. This is excellent news and progress so early on in our drilling campaign and, with a further well with additional high impact exploration potential to come, we look forward to updating our shareholders of further progress.”
