The joint venture partners have ended the current phase of operations ahead of flow testing the West Newton B-1Z (WNB-1Z) sidetrack well near Hull in East Yorkshire.
During December 2020, WNB-1Z encountered a gross 62 metre thick hydrocarbon bearing reservoir interval in the primary Kirkham Abbey target formation.
The JV today said that the cased hole logging programme (CHLP) and vertical seismic profiling (VSP) operations on the WNB-1Z well have now been completed.
CHLP results confirmed the presence of a good cement bond of the production liner and well bore integrity.
The VSP data will be used to refine the 3D seismic interpretation, primarily to be used in volumetric calculations towards reserve/resource figures for the West Newton field and to identify future well locations.
The JV said that initial indications from the VSP, which is being processed in Romania, showed that the data was of good quality.
NEXT PHASE
A service rig is expected to be used in the next phase of operations which include perforating and stimulating the Kirkham Abbey formation and subsequent flow testing of the well.
Well testing operations are expected to start during May 2021 and will take some four weeks to complete.
Following completion of operations on WNB-1Z, the JV will start testing the WNA-2 well.
Thin section images obtained from core plugs taken from the West Newton B-1Z well show porosity throughout the core including samples of between 12% and 15%.
The JV comprises Reabold Resources plc with 56% economic interest in West Newton via its 59% share in the site operator Rathlin Energy (UK) Ltd, which in turn holds 66.67% interest in PEDL183. Reabold also has 16.665% direct interest in the licence and Union Jack Oil plc holds 16.665%.
The licence contains West Newton A-1 (WNA-1) discovery well, the West Newton A-2 (WNA-2) appraisal well and the recently drilled WNB-1Z discovery.
