Aminex Suspends Well Offshore Tanzania
Aminex has suspended appraisal drilling on the Nyuni-2 exploratory well offshore Tanzania, due to severe drilling conditions.
The well had reached a depth of 3,450 meters and cased to 2,945 meters. However, it was not possible to run a full suite of electric logging tools to total depth as a result of obstructions near the base of the well bore.
Aminex repeatedly tried to drill out the obstructions in the well but was unsuccessful, so a decision was made to cement off the lower section of the well bore and deviate around the obstructions using a sidetrack motor. Aminex stated that although Nyuni is geologically complex, the prospect remains a prime exploration target and preliminary indications of gasses from Neocomian and shallower Cretaceous sands were encountered, suggesting the same active petroleum system encountered in Nyuni-1. The Nyuni-2 well bore remains available for re-entry at a later date, said the operator.
Once work is completed at Nyuni Island, the rig will mobiliz to the onshore Ruvuma Basin in southern Tanzania where Aminex will spud the Ntorya-1 well. Partners in the well are Aminex (operator, 65%), RAK Gas (25%), Bounty Oil (5%), and Key Petroleum (5%).SubseaIQ provides focused, in-depth coverage of offshore field development activities around the world, with daily updates on hundreds of offshore fields and facilities.
