Lion Energy Limited provided an update on the testing of the Lofin-2 gas well as part of the ongoing evaluation of the 1.5 TCF (2C) Lofin gas discovery in the Seram (Non-Bula) Production Sharing Contract ("PSC"). Lion has a 2.5% participating interest in the PSC. Following the initial 2-3 day shut-in period, which commenced on 13 February 2023, to monitor pressure build-up, the well will be re-opened for the multi rate flow test period.

This will be followed by a more extended shut-in period to monitor pressure build up and help confirm reservoir volumes. Lion will continue to keep the market informed on the ongoing test results. The objective of the Lofin-2 testing operations is to isolate the deep-water leg in the well and determine the reservoir hydrocarbon fluid characteristics and the deliverability of the target Manusela limestone.

The test string was run in the Lofin-2 wellbore on 4 February and the testing tool opened for an initial clean up period on 8th February. Gas to surface was achieved following controlled flow back of the water cushion/completion fluid. Rates of up to 14.8 mmscfgd were recorded on the 80/64" choke with 800 psi well head pressure (WHP).

The final test before first shut-in period was at a 16/64" choke with a rate recorded of 11.53 mmscfgd/58.6 bcpd (API:37), less than 1 bwpd (representing completion fluid) with 4150 psi WHP. Only 3% CO2 was recorded in the gas. Tested interval was at 15155' measured depth (MD) - 16656'MD/4619-5077m MD.

The discovery well, Lofin-1, was drilled in 2012 and provided encouragement for further appraisal drilling following flow rates reaching 15.7 MMscfD. The well measured depth of 4,427m (4,410m TVD) was however constrained by mechanical issues and therefore an appraisal well was planned. The appraisal well Lofin-2 was drilled in 2015 to a measured depth of 5,861m (5,791m TVD) and confirmed a significant gas discovery, with a reservoir section of up to 1,300m.

The Lofin Field is a thrust faulted four-way dip anticline located 50-km west of the producing Oseil oil field. The field is mapped on 1990 and 2008 vintage 2D seismic lines and is approximately 4km wide and 10km in length. While Lion has a 2.5% interest in the Seram (Non-Bula) PSC portion of the Lofin discovery, part of the field is mapped to extend into the East Seram PSC in which Lion has a 60% interest.

The reservoir is the fractured carbonate of the Jurassic/Triassic age Manusela formation which is the reservoir in the nearby producing Oseil oilfield.
