Transerv Moves Ahead with Warro Drilling Program in Australia

Transerv Energy has started two-well drilling program aimed at unlocking the value of Australia’s biggest undeveloped onshore gas field in the mid-west of WA.

The first well in the program at the Warro gas field, Warro 5, was spudded at the weekend and is expected to take 28 days to reach the planned total depth (TD) of 4250m, the company said Tuesday.

Transerv will then drill Warro-6 before undertaking reservoir stimulation and testing of both wells.

According to the company, the independent study by a US-based team of tight gas experts found this deep-seated faulting was likely to be the source of the water encountered in the Warro-3 and Warro-4 wells.

“The study indicated that Warro contains a substantial volume of gas with the potential to flow at high rates. Wells may be capable of delivering 4-10 billion cubic feet of gas each (50acre spacing) with existing water results and more (7-12 Bcf) if the water can be reduced or avoided by drilling away from the faults. The study also confirmed an in-place gas resource of 8- 10 trillion cubic feet with potentially 3-4 Tcf recoverable if appropriate reservoir stimulation is successfully carried out Warro-5 and 6 are designed to demonstrate the ability of wells in the Warro Field to flow gas at commercial rates and avoid the issues associated with excessive water in Warro-3 and 4 wells,” the company stated.

Warro-5 and 6 are the first wells to be located with the benefit of the Warro 3D seismic, which has provided a clear picture of the gas zones, deep-seated faulting and the field outline.
