When a failure of the production packer caused the shut-in of a 2,800m deep offshore production well, the operator needed a safe and efficient solution to remediate the primary barrier between the reservoir and the annulus and to return the well to service as soon as possible.
With production targets to meet – and the excessive cost and time associated with deploying a conventional hydraulic workover unit (HWU) to contend with – the operator turned to BiSN for their innovative rigless Wel-lok™ PRT (Packer Repair Tool) which creates a V0 qualified permanent barrier with bismuth based alloys in the annulus, something that cannot be achieved with existing traditional solutions. Our recommendation of a rigless intervention and reactivation wouldn’t just be a safer, more time-efficient and cost-effective solution – it would also be a world-first.
