Origin Energy Ltd. started fracturing activities on the Kyalla-117 well in the Velkerri liquids-rich gas play in the Beetaloo subbasin, Northern Territory, Australia.
Origin, in joint venture with Falcon Oil & Gas, drilled the well in January, but was forced to suspend fracturing plans when the COVID-19 pandemic caused state border closures and consequent restrictions on movement of personnel and equipment (OGJ Online, Dec. 10, 2019).
The well is seen as a test of frontier Beetaloo subbasin region potential.
The Kyalla-117 appraisal, near Daly Waters, was drilled to a total depth of 3,809 m with a 1,579 m lateral section. During drilling, elevated gas shows associated with relatively high liquids content were encountered in all three of the target reservoirs—the Velkerri, Hayfield, and Kyalla formations.
Fracturing of the zones will be followed by production testing.
Initial results are expected by yearend with full results available during first-quarter 2021.
Origin is financing current operations, up to $25 million (Aus.), as part of its farm-in agreement with Falcon.
Origin is operator with 77.5%. Falcon holds the remaining 22.5%.
