Drilling results from Rathlin Energy’s West Newton B site in East Yorkshire indicate a “substantial hydrocarbon accumulation”, partners said this morning.
A statement by Reabold Resources, which holds a 56% stake in the West Newton licence, said the results of the operations:
“have exceeded pre-drill expectations, further suggesting that the West Newton discovery would be the largest UK onshore discovery since 1973.”
It said the estimated hydrocarbon column in the target Kirkham Abbey formation was “at least 118 metres, significantly exceeding previous observations”.
Another partner in the licence, Union Jack Oil, said the sidetrack well, WNB1z, had encountered a 62m hydrocarbon saturated interval in the Kirkham Abbey formation.
It said there was “scope for the overall hydrocarbon column to considerably exceed the current identified interval”.
Last month, results showed that the secondary target, the Cadeby formation, was unsuccessful at West Newton B.
Today’s statement said drilling operations had now concluded and production casing had been run in preparation for a well flow test.
The drilling rig and associated equipment would be demobilised before the end of the year, the statements said.
Sachin Oza, co chief executive of Reabold, said:
“West Newton continues to surpass expectations and we are confident that it will be the largest onshore UK discovery since 1973.
“With more analysis to be done, we believe that these indications augur extremely well for the future of the West Newton project, which has the potential to be a meaningful and crucially local source of hydrocarbons for the Humber region.”
Fellow chief executive at Reabold, Stephen Williams, said:
“The B-1Z well has indicated substantial areal extent by discovering the Kirkham Abbey, located 2.5km from the previous A-2 discovery. With better-than-expected porosity and a positive comparison versus the A-2 well, the B-1 well has significantly increased the size of the observed hydrocarbon column, and we are yet to encounter an oil water contact demonstrating the potential for further upside.”
David Bramhill, executive chairman of Union Jack Oil, which holds 16.665% in the West Newton licence, said:
“There remains an extensive number of technical studies to be carried out to complete analysis of the WNB1Z well data, including correlation of the A1, A2 and B1Z well results and updated resource volumetric estimates, all of which will have a bearing on the planning and timing of the testing programme which is the next important milestone in determining the development potential of the West Newton project.”
