UK Oil & Gas: Provides UK onshore operational update
UKOG is pleased to announce that it has recovered measurable volumes of light oil and solution hydrocarbon gas to surface from the Kimmeridge reservoir section during well clean-up operations, at its 100% owned Broadford Bridge-1z (“BB-1z”) exploration well, located in licence PEDL234. The well has also free flowed for short periods during the well clean-up sequence in which spent completion fluids mixed with hydrocarbons were returned to surface. Well clean-up operations, utilising a high capacity linear rod pump, continue. Further developments will be reported in due course.
To ensure that the flow testing of Kimmeridge reservoir zones is fully optimised, the Company will proceed ahead to workover the well and implement a revised testing programme. The well clean-up operation will continue, then the current multi-zone completion assembly will be retrieved, the well worked over and flow tested sequentially over multiple, individual reservoir zones. Additional perforated zones will be added to the existing 1064 ft aggregate perforated section.
This operationally more flexible test operation will utilise a similar methodology to that successfully undertaken at the Horse Hill oil discovery, albeit with a much-increased initial lifting capability. The rig-less test will involve both nitrogen lifting and pumping as permitted under BB-1z’s current regulatory consents.
