Drillbit bites at Cobra
EnCore Oil said today that the Cobra appraisal well, in Block 48/2c, in the
southern sector of the UK North Sea, had spudded.
The main objective of the 48/2c-5 well will be to establish whether the
reservoir is capable of flowing at commercial rates. The well is being
drilled up dip from the 48/2-1 well, drilled in 1984, which flowed at 2.7
million cubic feet per day from a Rotliegendes Sandstone reservoir.
EnCore said that analysis indicates that the reservoir was damaged during the
drilling of the 48/2-1 well and that the reservoir performance could be
improved by the use of modern drilling and completion techniques.
The EnCore operated well is being drilled by the Ensco 80 jack-up rig and will
be managed by Applied Drilling Technology International (ADTI).
EnCore has a 20% stake in the licence and will pay for only 3% of the
appraisal well cost, subject to an overall well cost cap.
