Second Well in Malaysia Campaign Flows at 2,800 bopd
20 July 2026 - Singapore: Jadestone Energy plc (AIM:JSE) (the "Company" and together with its subsidiaries, "Jadestone" or the "Group"), an independent upstream production and development company focused on the Asia-Pacific region, is pleased to announce that the second well in the 2026 Malaysia infill drilling campaign has been successfully drilled and brought online at 2,800 bopd. This follows the positive outcome of the first well in the programme, announced on 24 June 2026, which achieved a peak production rate of ~3,200 bopd.
The second well in the 2026 campaign, EBA-07ST1, was drilled ~13% below budget with a 930-metre horizontal reservoir section at a total measured depth of 5,473 metres. As an extended reach well, it is the longest drilled to date on the East Belumut field (Jadestone 60% interest), exceeding the length of the first well in the 2026 campaign by 600 metres. Furthermore, with a 4.1 ERD ratio[1] the well set a new Malaysia record in extreme reach drilling, further demonstrating Jadestone's in-house drilling capability.
As previously announced, the encouraging results of the first two wells in the 2026 drilling programme resulted in a decision to drill the third contingent well. Drilling and completion activities on the third well have recently been concluded, with results to be reported in due course.
T. Mitch Little, Chief Executive Officer of Jadestone, commented:
"Following on from the excellent results of the first well in the 2026 East Belumut campaign, the second well has delivered a similarly positive outcome. It sets a new record for extended reach drilling across all basins in Malaysia, a very impressive milestone by our drilling team. In aggregate, the first two wells have increased production from the field by over 150% (an increase of ~6,000 bopd) - further validating our proven capability to unlock reserves, and create value in existing fields, by identifying and executing on opportunities bypassed by previous operators. We look forward to updating the market on the third well in the near future."
