Spanish operator Repsol has been unsuccessful with its Beebei-Potaro oil exploration well on the Kanuku block offshore Guyana.

Co-venturer Tullow Oil confirmed the wildcat, which has been completed, encountered good quality reservoir in the primary and secondary targets but both targets were water-bearing. Beebei-Potaro was expected pre-drill gross resources of approximately 200 million barrels of oil, Upstream had reported on 1 June.

The Noble Regina Allen jack-up rig drilled the Beebei-Potaro well to a total depth of 4325 metres from a water depth of 71 metres and the well has been plugged and abandoned.
