Empire Energy Group Limited announced 4 ½" production casing has been successfully run and cemented in 2 days following the drilling of the 4,460 metre (14,633 ft) well. The production casing program was fully executed as programmed to maximise the available wellbore and optionality for the upcoming fracture stimulation and the extended production testing program at C-3H scheduled to commence in early December 2022. A comparison to other recent analogue Beetaloo wells is included in Appendix A to this announcement.

The C-3H well, which targets the Velkerri-B shale formation and includes a Beetaloo record- breaking 2,632 metre (8,635 ft) horizontal section, was drilled on time and under budget in 39 days from drilling commencement to rig release on 21 November 2022. Empire's 3,150 metre (10,335 ft) Carpentaria-2H (C-2H) well which included a 1,345 metre (4,413 ft) horizontal section also took 39 days from drilling commencement to rig release, demonstrating Empire's ongoing rapid learning curve. Empire is currently mobilising to undertake the programmed ~2,000 metre (~6,500 ft) fracture stimulation optimised over the length of the C-3H horizontal section this year.

The C-3H fracture stimulation design will benefit from cutting-edge technological learnings from Empire's C-2H fracture stimulation and flow testing program, which is likely to enhance well productivity, particularly flow rates. Carpentaria-4V Update: Following the release from C-3H, Schlumberger Land Rigs 185 is being moved to drill the vertical C-4V appraisal well in the adjoining Carpentaria East Area. Empire expects to commence drilling in early December.
