ADES rig confirmed for offshore Indonesia Mako wells
Conrad Asia Energy subsidiary West Natuna Exploration has executed a binding contract for a jackup rig to drill the Mako gas field development wells offshore western Indonesia.
Mako is in the Duyung PSC in the Natuna Sea. The contract for the Admarine 502 jackup rig is with PT Pertamina Drilling Services Indonesia via the PDSI – ADES consortium.
The work scope covers drilling of six wells and installing the conductor support frame. The contract’s firm period is 180 days, with options to extend.
Operations should start during second-quarter 2027.
The wells will be tied back to a leased MOPU, with produced gas sent initially through a 59-km, 18-inch pipeline to the KF platform in the adjoining Kakap PSC, then onward through the WNTS pipeline to Indonesia’s domestic market.
Estimated capex to first gas is $320 million.
Conrad Asia Energy and its majority-owned subsidiary West Natuna Exploration Ltd. (WNEL) announced FID on the Mako gas project in early March.
