Senex Energy Ltd, through wholly owned subsidiary Stuart Petroleum Pty Ltd, is continuing to plan for an extended production test at the Gemba 1 gas exploration well, in PEL 516, located in the Cooper-Eromanga Basin, in mid-2019.Â  The production test is planned to determine the commerciality of the discovery with potential for first gas by end 2019.  The Gemba 1 well was spudded on 23 April 2018. The well was initially suspended at a total depth of 2,795 m after encountering gas shows in the target formations and the Dullingari Group. On 17 December 2018 Senex reported that a post-frac stabilised flow rate of approximately 8 MMcfg/d had been achieved during a seven-day flow test.   A seven-stage hydraulic stimulation programme was performed over the interval 2,360 - 2,730 m during November 2018. During subsequent testing, 44 MMcfg and 88 bbl of liquids was produced, stabilising at a rate of 8 MMcfg/d with approximately 20% carbon dioxide content. The test also validated a potential new gas play in the Dullingari Group. Senex reports that the pre-drill estimates of 15 Bcf of recoverable gas may well be exceeded.  Gemba 1 targeted the intra-Patchawarra Formation low-permeability sands and had a planned total depth of 2,685 m. During drilling, gas shows were observed across the target intervals and in the Dullingari Group.  PEL 516, which covers an area of 1,520 sq km, was awarded on 21 May 2010.Â  Stuart Petroleum Pty Ltd holds 100% interest and operatorship of the permit.
