Plans for Development
The operator's current field development plan envisages an initial four well development scheme, a small platform with compression facilities and an additional four wells as a second phase to be drilled later in the field's life. The plateau production rate is envisaged to be up to 90 MMscf/d.
A series of prospects both beneath and above the Mako field have been mapped. Of particular note is the Tambak 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%.
A drilling campaign is being planned for 2019 and a test of the Tambak prospect is to be a part of the programme.
