UK: Rathlin Energy begins extended well test at West Newton A-2 appraisal well
23 Aug 2019
Rathlin Energy reports that flow testing of the West Newton A-2 conventional appraisal well (WNA-2), located within PEDL 183, has commenced. The well test programme is scheduled to continue for the next 4-8 weeks.
Additional information regarding the test programme will be made available once the relevant data has been collected and analysed.
The West Newton A-2 well was spudded on 26 April 2019 and on 9 June 2019 reached a total depth (TD) of 2061 metres. 28 metres of core was successfully extracted from the primary target, the Kirkham Abbey formation, and all planned logging operations were completed.
A net 65 metre hydrocarbon saturated interval was encountered from within the Kirkham Abbey formation indicating a substantial hydrocarbon accumulation, including a significant liquids component.
The extended well test will establish flow rates and will help determine the future drilling and development programme at the West Newton project.
The initial petrophysical data obtained from the West Newton A-2 well correlates positively with the results from the West Newton A-1 conventional discovery well. Prior to the drilling of the West Newton A-2 well, a Competent Person`s Report compiled by Deloitte, had a Best Estimate Contingent Resource of 189 Bcf of gas equivalent. Volume expectations will initially be updated following further core and log analysis, then again following the extended well test.
The well also encountered hydrocarbon shows within the deeper Cadeby formation, a secondary target. The intersection is consistent with the West Newton A-1 well from which an oil saturated core was recovered. This is highly encouraging, and the formation is planned to be intersected in the future from the West Newton-B well location, where optimal reservoir development is expected, and planning permission is already in place.
