Duyung PSC, Operational Update
Empyrean has been advised that the Asian Endeavour-1 jack up rig, owned by China Oilfield Services Limited ("COSL"), has mobilised from
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. For further information on the drilling campaign, refer to the announcement made on

The Mako Gas Field, Duyung PSC, Offshore Indonesia
The Mako gas field is an extremely large, shallow structural closure, with an area extent of over 350 square km. The reservoir is a Pliocene-age sandstone, with a gas-water contact at approximately 391m true vertical depth sub-sea. The field has excellent seismic definition with direct hydrocarbon indicators being very evident.
Having been drilled but not tested by prior operators of the acreage, the commercial viability of the Mako gas field was demonstrated by the Mako South-1 well drilled by Empyrean and its partner and operator,
The Mako field is located in the prolific West Natuna basin, approximately 16 km from the WNTS pipeline system which delivers gas from Indonesia to Singapore. A plan of development has recently been approved by Indonesian authorities and initial gas marketing discussions have commenced, with a gas buyer in Singapore for the Mako gas. An independent report on the field's potential was recently carried out by
Near Field Exploration Potential, To Be Tested in 2019
A series of prospects both beneath and above the Mako field have been mapped. Of particular note is the Tambak (formerly 'Mako Deep') prospect, a Lower Gabus structure that sits beneath the northern end of the Mako field. The target interval within Tambak exhibits seismic amplitude brightening, conformable with structural closure. The prospect has a prospective resource range of 200 to 300 Bcf with a mid-case 250 Bcf and a CoS of 45%.
At the southern end of the field, over the structure's crest, sits the Mako Shallow prospect. This again shows a very strong direct hydrocarbon indicators on seismic, conformable with closure in shallow Muda sandstones. The Shallow Muda prospect has potential to add a further 100 Bcf of recoverable resources and a very high CoS of 75%.
