Regulatory Update: 18-month Planning Extension Approved,

Broadford Bridge-1 and 1z Kimmeridge Oil Discovery, Licence PEDL234, Weald Basin, UK

UK Oil & Gas PLC (London AIM: UKOG) is pleased to announce that West Sussex County Council's Planning Committee have approved, by a significant majority vote, an 18-month extension to the existing planning permission covering its 100% owned and operated BB-1 and 1z Kimmeridge oil discovery, located in licence PEDL234. The planning extension, which will expire in March 2020, will provide the Company with the necessary time to complete its plans to re-enter the BB-1 well to drill and flow test a new Kimmeridge sidetrack, BB-1y.

Drilling of the BB-1y sidetrack well is planned to directly follow the drilling of the new 2019 Kimmeridge exploratory and overlying Portland gas appraisal well in the basin-centre area of PEDL234, a planning application for which is expected to be submitted this Autumn. The drilling of the sidetrack and new PEDL234 well are subject to the grant of necessary regulatory consents.
