In late 2009, the Joint Venture completed the Gingin West 1 well to a TD of 3870m, targeting Block B within the Gingin West Prospect approximately 3km from a connection point on the Parmelia pipeline.
This target is a simple anticline to the south of and updip from the Bootine 1 well. The main objective was the sand that flowed gas at Bootine 1, with other shallower sand members of the Cattamarra Coal Measures offering further prospectivity.
The Gingin West 1 well resulted in an inferred discovery within the Cattamarra Coal Measures that have proven productive for hydrocarbons within the Mount Horner field to the West, and the adjacent Gingin wells.
The well has been cased and suspended as a potential future producer and the Joint Venture plans to test 2 interpreted hydrocarbon bearing intervals:
The 3760m D Sand – The interval indicating hydrocarbon is 3760m to 3777.5m MD. The perforated interval proposed is 3764.5m to 3773m MD. This equivalent interval in the Bootine-1 well flowed gas at a rate of 2.2 million cubic feet of gas per day.
The Top D Sand – The interval is 3571.5m to 3586.8m MD, and it is proposed to perforate the interval 3572m to 3575m MD. This sand recorded very good hydrocarbon fluorescence and a gas peak while drilling.
Additional targets exhibiting condensate-rich gas kicks up to 75 units have been identified within the coaly intervals between 3187m and 3385m. These intervals may be tested in a later program.
