The AAL-4X well will be drilled to a planned maximum total depth of 1232 m TVDSS and is forecast to take approximately 48 days to complete. The well is being drilled in water depth of approximately 72 m using the Raniworo jack-up drilling rig.
The Northwest Natuna PSC is located offshore Indonesia and includes the Ande Ande Lumut (AAL) oil project. The AAL project comprises the K Sand reservoir (101 million bbls, net 24.3 million bbls of 2P Reserves to AWE) and the underlying G Sand reservoir.
The AAL-4X appraisal well is targeting the G Sand reservoir, which is estimated to contain 289 million bbls gross oil in place with 36 million bbls gross recoverable oil (net 10 million bbls 2C Resources to AWE). Appraisal of the G Sand will facilitate the preparation of Plan of Development for this resource, which could be developed in conjunction with the already approved K Sand development.
