PERTH, Western Australia -- Carnarvon Petroleum has been awarded 100% of a new permit offshore Western Australia.
Application block W08-11, covering a total area of 4,955 sq km (1,913 sq mi), is in the northwest part of the Bedout sub-basin within the greater Roebuck basin. According to Carnarvon, this is an under-explored area, but adjacent to the prolific Carnarvon basin hydrocarbon province to the southwest. Water depths range from 125-265 m (410-869 ft).
Three wells have been drilled in the block, two of which intersected gas columns in the Phoenix structure in a low-porosity, mid-Triassic reservoir. The Phoenix-1 well recorded a 110 m (361 ft) net gas-bearing section, but Carnarvon says further work is needed to determine whether commercial flow is feasible.
The company has committed to reprocess 2,500 km (1,553 mi) of existing seismic in the first three years of its program and to conduct technical studies, but it also will look at ways of accelerating appraisal drilling on Phoenix and adjacent structures. After this first phase, it intends to acquire new seismic and to drill at least one well.
