3 Sept 2026 · Brookside Energy Limited
Whalers reached planned depth with casing cemented and Rig 18 released, completing drilling of both Suttles wells with full planned laterals in target formations. Zipper-frac completion is next, then sales. No flow rates or costs reported yet.
2 Sept 2026 · Brookside Energy Limited
Completed purchase of Lone Star's US oil and gas interests, a Stonehorse subsidiary, for US$1.114m (~US$9,100 per flowing BOE/d). Adds ~123 BOE/d, about 9% of Q2 production, with no new shares issued. Stonehorse is Brookside's Orion partner.
2 Sept 2026 · AXP Energy Limited
The 320kW gas-to-power unit is operating with 99% uptime. Charlie #1 flowed 11 bbl of oil in a one-hour test, choked to ~100 psi; the company says this is not a stable daily rate. A 10-day flow test follows.
31 Aug 2026 · AXP Energy Limited
AXP and Simpora mutually terminated the Syria Block 9 farm-in, citing timing against AXP's Oklahoma priorities. Simpora keeps the US$100,000 deposit; no further payments are due. This reverses the June 'transformational' deal, with the US$1m payment never made.
31 Aug 2026 · 88 Energy Limited
The PEL 93 joint venture applied to enter the Second Renewal Exploration Period from 3 October 2026, proposing at least one exploration well and relinquishing 50% of the area. Prospect 9 is confirmed as top target; ReconAfrica's nearby Kavango West 1X flows support the basin. Renewal is not yet granted.
31 Aug 2026 · Strike Energy Ltd
Strike chose Hancock Energy's proposed Belisama plant to process its West Erregulla gas, at a fixed capacity charge, with a term sheet for a loan of up to $30m (needs Macquarie consent). Upstream FID is now FY28 with first gas mid-CY29. South Erregulla approval to generate is now targeted for late Q4 CY26.
31 Aug 2026 · Blue Star Helium Ltd
The helium offtake with the unnamed US buyer, due to expire 31 August 2026, is extended to 31 March 2027 at a fixed price, still covering all Pinon Canyon output. This resolves the near-term expiry catalyst; long-term offtake talks continue.
28 Aug 2026 · ADX Energy Ltd
HOCH-1 Zones 3, 4 and 5 all flowed water-free gas, and commingled with Zone 2 produced 3.15 MMCFPD (548 BOEPD) over 12 hours. The well is shut in for pressure build-up to determine reserves; deeper Phase 2 testing needs a workover rig.
27 Aug 2026 · Horizon Oil Ltd
FY26 results: record production of 2.15 MMboe, EBITDAX US$56.4m, operating cash flow US$47.2m and cash US$37.4m. A final dividend of A$0.01 per share (A$17.4m) is payable in October 2026. Cue is consolidated for only 13 days.
21 Aug 2026 · Lakes Oil NL
Entitlement offer closed raising $1.9m of the $4.69m offered at $0.30, with underwriters covering a further $0.8m. About $2.0m of shortfall remains unplaced. Placement raised $3.3m, plus $0.7m needing shareholder approval on 23 September. Total so far falls short of the ~$8.7m target.
20 Aug 2026 · Texas Mineral Resources Corp.
Texas Mineral Resources Corp. deregistered its securities, ending its obligation to file reports with the SEC.
19 Aug 2026 · Horizon Oil Ltd
First gas flowed on 11 August 2026 from the Sinphuhorm Pad D facility in Thailand, about 50 days early; the PH-14 well tested at 25-30 MMSCFD gross. Horizon holds an effective 7.5% interest. This delivers the Pad D first gas flagged for later 2026.
