Union Jack Oil plc (LON:UJO) a UK focused onshore hydrocarbon production, development and exploration company, has announced that operations have commenced on the Wressle-1 well to install a downhole jet pump and associated surface facilities as part of the planning to optimise future production.
Union Jack holds a 40% economic interest in the Wressle development.
Operations began with a slickline programme, which has now been completed, where downhole pressure and temperature gradients were acquired. The work programme includes recompleting the well for the installation of a downhole jet pump and the siting of associated surface equipment.
The operations are scheduled to take approximately three weeks and production from Wressle-1 is expected to be reinstated during late September 2023.
Data obtained from these activities will be incorporated into the ongoing work by ERC Equipoise Ltd and the expected beneficial impact on production of the artificial lift from the jet pump will be included within their independent Competent Person`s Report, the details of which will be announced once this work is completed.
David Bramhill, Executive Chairman, commented: “Industry sources indicate that over 90% of oil wells employ artificial lift during their life-cycle, therefore, the natural sequence of the installation of a jet pump on the Wressle-1 well offers a reliable method of ensuring the continued operation and the optimisation of its future production performance.”
