Sunshine Gas Says Overston 2 Workover Successful
Sunshine Gas reports that the Overston 2 workover has now been successfully completed with all objectives met.
Managing Director, Tony Gilby, said he was pleased that the result was inline with the objectives of the workover and has increased the likelihood of establishing conventional gas reserves for Sunshine Gas in the Overston area.
A stabilized gas flow rate of approximately 500,000 cubic feet per day accompanied by hydrocarbon liquids has been achieved. The gas flow was through a 1" choke and was measured using a "Flow Prover".
Sunshine Gas is now completing studies to assess the reserves associated with Overston 2 and various development options.
The well completion commingles gas from three sandstone intervals being the Basal Sandstone from 3,105 to 3,110m, the Overston Sandstone from 2,995 to 3,005m (which would not flow stabilized rates after hydraulic fracture stimulation), and the Tinowon Sandstone from 2,887 to 2,910m – all of Permian age.
The well has now been shut-in and an extended well test is planned to follow. The well test will be through a separator so that the volume of hydrocarbon liquids being produced can be accurately measured.
