LONDON – Caithness Petroleum has updated its exploration program on the Lybster field in UK North Sea block 11/24.
In 2010/11, Caithness re-entered, side tracked, and extended its L11/24-3 well (drilled from land) into the eastern part of Lybster to twin the original vertical discovery well.
A side track well, L11/24-3z, was completed for production, and test operations on the well have recently finished. These delivered flow rates of up to 1,900 b/d of 38° API oil through a variable choke set at 36/64-in.
The well has since been shut in pending completion of surface facilities, prior to the start of production.
Currently Caithness is preparing to acquire 2D seismic in the area, and also plans an offshore well to appraise the Knockinnon field in the same block.
