The joint venture partners at West Newton announced that the first phase of evaluation will begin in April of sidetrack well WNB-1Z at the site near Hull in the East Riding of Yorkshire.
The evaluation will include a cased hole logging programme (CHLP) and a vertical seismic profiling survey.
The JV comprises Reabold Resources plc with 56% interest in West Newton via its 59% share in site operator Rathlin Energy (UK) Ltd, which in turn has a 66.67% interest in the licence PEDL183.
In addition, Reabold has a 16.665% direct licence interest in PEDL 183 with Union Jack Oil holding 16.665%.
The licence contains the conventional West Newton A-1 (WNA-1) discovery well, the West Newton A-2 (WNA-2) appraisal well and the recently drilled West Newton B-1Z (WNB-1Z) discovery well.
The JV has also received from the Environment Agency a draft permit for the completion, well clean-up and extended well test (EWT) at WNB-1Z and additional well at West Newton B (WNB).
This follows an application from Rathlin to vary the permit already in place which includes further well clean-up and EWT operations on the WNA-2 well.
The processing and interpretation of data is expected to take two weeks and will inform completion, well clean-up and EWT operations for WNB-1Z well.
Preparations are also underway for an updated competent person’s report at West Newton.
EVALUATION PROGRAMME
The first phase of the evaluation programme on the WNB-1Z discovery well will initially be comprised of a customised CHLP including a cement bond log, a Weatherford Raptor evaluation tool to log the Kirkham Abbey Formation and a VSP survey.
The Raptor tool is a pulsed neutron wireline logging device that provides quantification and advanced analysis of oil, gas and water saturations and potential fluid contacts in a cased wellbore.
The cased hole logging activity will be followed by a VSP survey that will provide a high-resolution calibration of the existing 3D seismic data.
It is considered to be a more accurate method of calibrating previously interpreted formation tops and calculated time-estimated formation depths.
