Stonehorse Energy Limited announced that the planned workover programme on the Myall Creek-2 well located in the Surat Basin in SE Queensland has now been successfully completed. The workover plan was designed to test the Tinowon C reservoir by utilising a workover rig to clean out the wellbore to the top of the fish and recomplete the well by isolating the existing Tinowon A perforations behind a straddle packer and tubing arrangement, then perforate the Tinowon C through tubing. The previously un-produced Tinowon C reservoir has now been perforated, completed for production and ready for future stimulation.

The well is now undergoing a 30 day extended line production test and Pressure Build Up (PBU) to assist in the evaluation prior to fracture stimulation. At the end of the test period, a decision will be taken on the priority and timing of fracture stimulating the Tinowon C reservoir interval. A specialist pulsed neutron logging was also conducted during the workover operations over the Back Alley and Bandanna formations up hole, to confirm gas saturation as future fracture stimulation targets.

Log interpretation is currently underway.
