Drilling of Tambak-1 well begins

Empyrean Energy has announced that following the successful appraisal at Tambak-2 in the West Natuna Basin, offshore Indonesia, the Asian Endeavour-1 jack up rig has been on location since 1 November and drilling of the Tambak-1 well has commenced.

The Tambak-1 well is located approximately 4.5 km north of the Mako South-1 location and is designed to both appraise the extent of the Mako gas field as well to test the underlying Tambak prospect. The well will be drilled as a vertical well and is prognosed to intersect the top of the intra-Muda reservoir at a depth of approximately 1276 ft below sea level. The well will be deepened below the base Muda unconformity (at a depth of approximately 1696 ft) to test the underlying Lower Gabus section.

The well is planned to total depth at approximately 4500 ft below sea level.

Total time to drill, log and test in the event of success is estimated to be approximately 33 days, after which the well will be plugged and abandoned and the rig de-mobilised.

The gross cost of the two well programme is expected to be approximately US$17 million  – US$19 million to the PSC partners on a fully tested basis, including rig mobilisation and de-mobilisation, for which Coro Energy Plc is funding US$10.5 million. Empyrean will fund 8.5% of the additional drilling campaign costs over and above the Coro funding.
