Beach Energy Ltd. found no producible hydrocarbons in the Trigg 1 gas exploration well onshore Perth basin in southwestern Western Australia. The operator will now move the rig to its Trigg Northwest 1 well location.
Trigg 1 reached 4,914 m measured depth on June 3. Gas shows were present in the primary Kingia target however no gas could be recovered with wireline testing. The reservoir is interpreted to be tight with insufficient porosity and permeability to flow gas. Testing this significant southerly step-out of the Kingia play meant that reservoir presence and quality was the primary pre-drill risk for this prospect.
Trigg 1 will be plugged and the pre-planned side-track, Trigg 2, a contingent appraisal well, will not be drilled.
After Trigg Northwest 1, Tarantula Deep 1 and Beharra Spring Deep 2 will be drilled.
Beach is operator of the well (50%) with partner Mitsui E&P Australia (50%).
