Oilex Ltd says that the chemical treatment and well intervention was completed last month and a significant improvement in recovery rates has been observed.
During flowback operations Oilex Ltd planned to replace the frac tree with a standard production tree. As part of removing the frac tree, two (2) retrievable bridge plugs (RBP) are set in the well as safety barriers against the well flowing. In this instance, the first plug did not set and seal properly and moved downhole where it became stuck. Recovery operations were successfully completed in ~ 13 days.
Subsequent to the operations described above and further chemical treatment, flowback and clean-up again recommenced including recovery of frac water, oil and gas and the well exhibited significantly improved performance.
