Unconventional gas potential in Proterozoic source rocks: Exploring the Beetaloo Sub-basin

Origin acquired extensive wireline data, sidewall core and full core data in addition to undertaking real-time geochemical analysis of cuttings while drilling. These results indicate reservoir intervals contain gas-saturated, quartz-rich source rocks that are mature for gas over extensive areas, providing an excellent exploration target with material volumetric upside. Additional information from acquisition of pressured sidewall cores and diagnostic fracture injectivity tests (DFIT) complemented the reservoir assessment, yielding accurate data on gas composition, saturation and an estimate of pore pressure.
Results of the wells are positive and encouraging gas-in-place metrics were observed; however, substantial further work is required to continue to assess the key risk of delivering commercial flow rates from multi-stage fracture stimulated horizontal wells.
