Armour Energy Limited announced that the Warroon-1 fracture re-stimulation was successfully completed on 10 January 2022. All fracture stages were successfully pumped by Schlumberger with a total proppant placement of 159,826 lbs versus planned 157,500 lbs (just over 101%). By contrast, the previous stimulation in November 2020 achieved the placement of around 47,000 lbs.

Flow back commenced on 11 January 2022 but the well was unable to flow back unassisted. A coiltubing unit was mobilised on 13 January 2022 and clean out was conducted over 2 days. Broken stimulation fluid, as per design, was recovered on both days.

Overnight inflow ofliquids into the well bore demonstrated connectivity.Warroon-1 has been re-connected to the gas gathering system ready for inline clean upflow. The well is currently shut in on pressure build up. Preliminary results are not expected for3 to 4 weeks.

The workover programme on Myall Creek-2 has been successfully completed with the depleted Tinowon A reservoir now isolated. The previously un-produced Tinowon C reservoir has been perforated, completed for production and ready for future stimulation. A specialist pulsed neutron logging was also conducted during the workover operations over the Back Alley and Bandanna formations to ascertain gas saturation as future fracture stimulation targets.

Log interpretation is currently underway. The well has been reconnected to the gas gathering system and a 30-day in-line production test commenced on 17 January 2022. Initial gas flow rates are fluctuating between 200 ­ 400MSCF/day with produced has going to sales.

At the end of the test period, a decision will betaken on the priority and timing of fracture stimulating the Tinowon C reservoir interval.
