Empyrean Energy Plc has announced that the Asian Endeavour-1 jack-up rig, owned by China Oilfield Services Ltd (COSL), has mobilised from Singapore and is now en-route to the first well in the company's drilling campaign in the West Natuna Basin, offshore Indonesia, in which Empyrean holds an 8.5% interest.

The campaign will comprise of two wells, an appraisal well designed to primarily appraise the intra-Muda sandstone reservoir (Mako gas field discovery) in the southern area of the Mako field and an exploration well designed to test the Tambak prospect beneath the central area of the Mako gas field, after appraising the Mako gas field at that location.

The Mako gas field is an extremely large, shallow structural closure, with an area extent of over 350km2. The reservoir is a Pliocene-age sandstone, with a gas-water contact at approximately 391 m true vertical depth sub-sea. The field has excellent seismic definition with direct hydrocarbon indicators being very evident.
