Australia's Santos is planning drill stem tests on the G Sand and K Sand reservoirs as part of its Ande Ande Lumut (AAL) project offshore Indonesia.
AAL is in the Northwest Natuna production sharing contract, in the Natuna Sea, which operator Santos shares with AWE.
AAL, comprises the K Sand reservoir, estimated to contain 101 MMbbl recoverable, and the underlying G Sand reservoir, estimated to contain 289 MMbbl in place and 36 MMbbl recoverable.
The firm has already drilled into both reservoirs, with oil shows. Following wireline logging, drill stem tests will be carried out.
Appraisal of the G Sand reservoir will help the company prepare a development plan, which could be developed in conjunction with the K Sand development.
The latest AAL-4X well is being drilled in water depth of approximately 72m using the Raniworo jackup drilling rig
and is forecast to take approximately 48 days in total to complete.
