UK Oil & Gas Investments PLC has announced that 13 ? in. steel casing was set and cemented successfully over the 855 ft thick Weald Clay section on its 100% interest Broadford Bridge-1 (BB-1) Kimmeridge Limestone exploration well.
Directional drilling operations, within 12¼ diameter hole, commenced on Monday evening. BB-1 has now reached a depth of over 370 m (1200 ft) below surface within the Lower Cretaceous Hastings Beds. The uppermost Kimmeridge Limestone target, KL4, is expected to be conventionally cored in around 10 - 12 days' time. The well remains on schedule and within budget.
BB-1 is located near Billingshurst, West Sussex, within the 300 km² PEDL234 licence, in which the Company has a 100% interest via its ownership of the licence's operator, Kimmeridge Oil & Gas Limited. The well, an exploration step-out, is designed to penetrate four naturally fractured Kimmeridge Limestone units (KL1-KL4), the uppermost two units of which flowed at record rates in the Company's Horse Hill-1 discovery near Gatwick Airport.
The well is designed to drill through the target limestones at an inclination of around 50° to vertical and at approximately 90° to the predicted orientation of open natural fractures in the reservoir. The planned overall horizontal deviation of the well is approximately 1 km to the north-northeast of the well site. The Kimmeridge Limestones are expected to be encountered at a drilled depth of approximately 1300 - 1700 m, which equates to around 950 - 1200 m vertically below surface.
