The Tinowon reservoir was damaged by the original drilling process and the fracture stimulation was designed to provide additional information on reservoir characteristics.
During the test the well flowed gas at around 250,000 cubic feet per day along with condensate. No water was produced during the test.
The well has now been suspended pending additional fracture stimulation and potential completion as a gas producer at a later date.
The operator will now proceed as planned with the acquisition of a 3D seismic survey over the field followed by the drilling of the Overston-2 well. The seismic survey is scheduled to begin this month and will further define the Overston structure to allow optimal well placement.
Overston-2 will also fully evaluate the Showgrounds Sandstone, which was not tested in Overston-1.
Interests in the Overston field are Sunshine Gas 50% and Samson 50% (subject to completion of work program).
