Stonehorse Energy Limited announces that the Company and InvestorCo has partnered with Armour Energy Limited to take a 50% Revenue Interest in the workover and well intervention program planned for the Myall Creek-2 well, located in the Surat Basin in south east Queensland. The workover program is expected to commence in December 2021. The capital cost will be funded 100% in equal portions by Stonehorse and InvestorCO, consistent with its stated strategy of identifying and investing in low-risk, moderate production enhancement work programs. Armour have engaged Griffin Energy Solutions to design and complete well intervention operations. Griffin is an independent specialist Oil & Gas technical and operational consulting firm with a reputation for commercial rigor and significant knowledge and experience in the energy resources sector. The Myall Creek-2 well was an exploration well drilled by OCA in 1999 to appraise the Tinowon formation. Although the primary target was the Upper Tinowon, the well encountered high mud log gas readings throughout the intervals, from the Showgrounds through to the lower Tinowon formations. Myall Creek-2 intersected good quality reservoir in the Upper and Lower Tinowon formation. The Upper Tinowon reservoir was tested and flowed gas at 5.7 MMscfd and recovered condensate. The Lower Tinowon reservoir, while not tested, was similar to the Upper Tinowon and comprised a series of good quality fluvial channel sands with moderate to strong gas shows and fluorescence. The Upper Tinowon formation was perforated and bought online in April 2001 producing 1.7 Bcf over 5 years before it was fracture stimulated. The post fracture stimulation rate was ~3.0 MMscfd, more than six times the pre-fracture stimulate rate of ~0.5 Mmscfd, from a depleted reservoir. The Myall Creek-2 well is situated structurally high on an apparent, 3D interpreted, four way dip closure, with the lower Tinowon at virgin pressure. This reservoir is also laterally continuous.
