Proactive Investors - Union Jack Oil PLC (LON:UJO) has stated that installation is underway on the Wressle-1 well of a downhole jet pump and associated surface facilities in order to optimise future production.
Union Jack, a UK-focused onshore hydrocarbon production, development and exploration company, 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 in late September.
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 in its 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."
