Cliff Head Joint Venture (CHJV) is delighted to deliver the following Cliff Head Operations (Cliff Head) update regarding the start of the Cliff Head 10 (CH-10) Workover programme.
The CH-10 well was shut in, September 2021, due to a downhole electrical fault. This well had produced
reliably for nearly 12 years with the same Electrical Submersible Pump (ESP) and this performance
significantly exceeds the field average of 4 years.
This morning, Thursday, 9 June 2022, activities will begin on the CH-10 Workover to replace the failed
ESP and increase hydrocarbon production from this well. Over the coming months, the CHJV will
undertake a phased campaign to recover the failed ESP and replace it with a new ESP. In addition, a
deeper water producing reservoir will be isolated, with the aim to increase oil production. The phased
approach to this workover optimises the utilisation of the Hydraulic Workover Unit and budget spend in
alignment with long lead item delivery schedules.
The CHJV expects the successful workover will produce an additional circa 130 barrels of oil per day
(bopd) from CH-10 and see field production return to above 800 bopd.
