The Churchie West Joint Venture in which Mosaic will act as operator with an 83.3% interest, while Santos has a 16.66% stake, was awarded the PL 213 permit in April.
Expected to spud on October 8, the Churchie West-1 well is expected to take about 18 days to a planned depth of 2178m.
Mosaic told the Australian Stock Exchange this morning that the well would be drilled with nitrogen in the primary gas/condensate target reservoir, the Permian Tinowon Sandstone, which is productive in the adjacent Churchie and Myall Creek gas fields. Secondary potential also exists in the early Triassic Rewan Formation reservoirs.
If it makes a successful discovery, Churchie West-1 well would have extended the reservoir fairway from the Churchie field into PL 213.
Churchie West-1 is located about 2.5km south-southwest of the Churchie-3 Tinowon Sandstone gas producing well and 1.3km north-northwest of the Noorindoo-1 Tinowon Sandstone gas/condensate discovery well.
