Key facts

  • Well defined Mako gas field with low risk but high value step out exploration potential
  • Shallow depth of reservoir, circa400m, excellent seismic definition with strong amplitude signature and resolution to define reservoir architecture
  • The field development plan has been approved by the Indonesian authorities
  • The field is located close to the West Natuna Transportation System offering the potential to sell gas into the Singapore market
  • Favourable gas pricing in the developed Singapore market, with piped gas competing with LNG import
  • Mako Shallow prospect with mid-case resource potential of 100 Bcf and a CoS of 75%
  • Deeper stratigraphic exploration prospects have been mapped on 3D seismic data elsewhere in the PSC, these are being matured to drillable status.

Plans for Development

The operator's current field development plan envisages an initial four well development scheme, with a small platform with compression facilities, tied into the WNTS pipeline. An additional four wells, as a second phase, is to be drilled later in the field's life. The plateau production rate is envisaged to be up to 90 MMscf/d.

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%.

Following the successful appraisal campaign in Q4 2019, the resource estimates are being revised by Gaffney Cline & Associates.
