Tullow Oil Abandons Jaguar-1 Well Offshore Guyana

Drilling operations at the Jaguar-1 well in the Georgetown Block, Guyana, have ended and the well will be plugged and abandoned at a depth of 4,876 metres, without reaching the primary objective.

The decision to stop drilling at this point was unanimously agreed by all partners based on safety criteria and was taken after reaching a point in the well where the pressure design limits for safe operations prevented further drilling to the main objective.

Jaguar-1 was a high pressure, high temperature well which was spudded in February 2012 using the Atwood Beacon rig. Whilst the primary Late Cretaceous objective was not reached, samples of light oil were successfully recovered from two Late Cretaceous turbidite sands above the primary objective.
