The main frac pumping operations were completed on the morning of 24 May, and 80% of the planned quantity of proppant was pumped into the newly fractured reservoir. Prompt flowback of the frac fluid occurred without the need for coiled tubing operations.
The well is still in the process of cleaning up, with gas being flared off as frac load fluid is recovered. The main operation is now complete and the frac rig will be released within the week, the company said.
The company will continue to clean up the well and evaluate flow rates, pressure and frac geometry data.
The Churchie-1 frac has been performed so that Mosaic can determine the optimal formula for fraccing in the Tinowon reservoir.
If the trial proves successful, the company will further roll out the procedure to select wells in the Surat-Bowen Basin with the ultimate goal of enhancing gas flows from the tight gas reservoirs.
If successful, the application of fracture stimulation is expected to lead to significant increases in Mosaic’s total rates of production over the coming years.
