Evaluation of a well is underway at Rathlin Energy’s West Newton-B site in East Yorkshire.
A spokesperson for Union Jack Oil, one of the investors in the project, confirmed the work had begun after the arrival of equipment on 7 April 2021.
The evaluation operation, which had been announced to investors last month, comprises a cased hole logging programme on the WNB1z well, including a cement bond log.
A previous statement said a Weatherford Raptor evaluation tool would be used to log the Kirkham Abbey formation, one of the well’s targets. The tool was said to give a “quantification and advanced analysis of oil, gas and water saturations and potential fluid contacts in a cased wellbore”.
A vertical seismic profiling survey would also be carried out to calibrate existing 3D seismic data, the statement said.
Union Jack’s spokesperson said today:
“Processing and interpretation of data is expected to take two weeks. There is nothing else we can add at this stage but will communicate as soon as we have an update on operations from Rathlin.”
The evaluation data will inform well completion, clean-up and a future extended well test.
The road to West Newton B is closed but local reports have said the closure may be lifted early next week.
The WNB-1z well is a sidetrack, drilled in November 2020. This followed an announcement that the WNB well missed the Cadeby formation, the secondary target.
Rathlin Energy has reported that more than 370 people visited last month’s online exhibition about production and drilling plans at the West Newton A site.
The company said the week-long exhibition was designed to give local people and business owners an opportunity to comment on proposals before a planning application was developed. It said 10% of people who used the exhibition left feedback.
Rathlin Energy is proposing to drill a further six wells, triple the width of the site and produce oil for 20 years. A planning application is expected in the summer, it said.
