Warrego Energy Pty Ltd proposes to develop the West Erregulla-2 Exploration Well located approximately 50 kilometres south - east of Dongara. The proposal is a proof of concept (single well). The exploration targets are at depths of 2,000 metres (m) to 5,000m and include geological structures that may yield natural gas. This includes the Dongara tight sandstone which is found below 3,900m and is expected to require hydraulic fracturing.
