JKX Oil & Gas plc (“JKX”) has successfully completed the 10 stage multi-stage frac in well R-103 and the fracking equipment is now being demobilised. As reported in
JKX’s Chief Executive, Dr Paul Davies, commented:
“We are very pleased to have successfully completed this 10 stage frac operation in Ukraine. Conditions have been difficult but overall the execution has been better than anticipated. Seven of the frac stages have achieved or exceeded design predictions, two were below expectations and only one was unsuccessful. The next few weeks of cleanup and flow stabilisation will be critical and we are encouraged that the well is already flowing gas to surface together with frac fluids.”
The 10th stage was an additional stage, but was not successful, as even with a pump pressure of 825 bar (11,960 psi) the pumps were unable to achieve breakdown. Consequently, this final frac stage was abandoned.
The total volume of fluid injected was 4,600 cubic metres (29,000 barrels) and we expect to recover 15-25% of this volume before liquid- free gas flow commences.
