Duyung PSC Project


Empyrean has a 10% interest in West Natuna Exploration Limited that holds 100% of the Duyung PSC in offshore Indonesia.

The Duyung PSC covers an offshore permit of approximately 1,100km2 in the prolific West Natuna Basin.  The main asset in the block is the Mako shallow gas discovery. In addition, numerous prospects and leads have been identified in the block using 3D seismic data.

Empyrean participated in the appraisal well Mako South-1 in June 2017.  The well was drilled  using a jackup rig located in water depths of 308 ft.  The well reached a TD of 1,707 ft on 22 June 2017.

The Mako South-1 well exceeded the Company’s expectations encountering excellent reservoir quality rock with high permeability sands in the multi Darcy range with 23 feet of gas bearing reservoir. This zone flowed gas at a stabilized rate of 10.9 million cubic feet per day through a 2 inch choke. The gas is of high-quality close to 100% methane, no CO2, H2S, or other contaminants

Initial interpretation of the test results demonstrated that the sandstone reservoir is expected to be laterally contiguous, and has exceptional permeabilities in the multi Darcy range.

Two conventional cores were recovered successfully and further analysis is currently underway to assist with the overall assessment of results.
