Union Jack Oil PLC (LON:UJO) has updated on the ongoing drilling operation at the West Newton B-1 appraisal well project in East Yorkshire.
The well, tagged WNB-1, has so far been drilled down to a depth of 2,295 metres and Union Jack confirmed it has encountered both the primary (Kirkham Abbey) and secondary (Cadeby) objectives.
The Kirkham Abbey formation indicated a hydrocarbon charge based on wireline logs, cuttings and mud gas readings, the company said, while for Cadeby there was insufficient reservoir development.

The venture partners have now begun a side-track drilling operation from the WNB-1 well and Union Jack expects that West Newton B-1Z (WNB-1Z) will be drilling ahead during the next few days.
The purpose of the side-track is to further appraise the Kirkham Abbey formation on a structurally superior location. Findings from WNB-1 and WNB-1Z wells will inform the optimal locations of future development wells at the West Newton project, Union Jack added.
Union Jack owns a 16.665% interest in West Newton.
