Strong results from Malaysia drilling campaign

Jadestone Energy has announced that the final well in the Company’s 2023 East Belumut field drilling campaign offshore Peninsular Malaysia has now been completed.

The overall programme has delivered results significantly ahead of expectations. The Company is also pleased to provide an update on Group production, progress on the Akatara project and recent crude oil liftings.

The fourth and final well in the East Belumut infill drilling campaign is currently being tested after reaching 4600 m measured depth in the south west of the field. This is approximately 730 me measured depth more than originally planned, due to the better than expected oil column encountered at the toe of the well, and the longest reach horizontal well ever drilled in the field. Overall, a 1700 m horizontal section was drilled in the target formation, aided by successful optimisation of the well trajectory using geo-steering tools. The well is expected to produce at initial rates in excess of 3500 bpd.


Combined with the three wells drilled to date, which are currently producing at an aggregate gross rate of 7000 bpd, the results of the East Belumut infill campaign have far exceeded expectations, which were for initial gross aggregate rates from all four wells of 3500 bpd. The drilling capex will be cost recovered and pay-back is expected by 2Q24 next year. The well results are already being used to update the geological model for the East Belumut field, will have a positive impact on reserves, and are likely to provide a number of new infill targets for future drilling campaigns.
