Synergia Energy has provided the following update concerning the current workover of the Cambay C-77H well.
Workover operations have proceeded according to expectations and commenced on July 15th when the C-77H well was 'killed' prior to the removal of the production tubing. This was followed by the milling out of the bridge plug that had isolated the original four fracked zones from the two re-frac zones above the bridge plug. The production tubing was then re-inserted and flow back of the kill fluid commenced. Due to the presence of an extensive column of condensate in the wellbore, nitrogen lift was employed to assist with the flow back.
The workover rig was redeployed to the C-19z well on July 24th for a minor de-waxing workover.
The C-77H will be flowed for a period to satisfy the request of the Directorate of Hydrocarbons ('DGH') to establish a baseline of production without artificial lift. Over the coming weeks, the well performance will be observed after flow rates have stabilised. Following the establishment of the baseline of production, the workover rig will be re-deployed over the C-77H well for the installation of the jet pump artificial lift system. The jet pump installation is scheduled for mid-August 2023.
