Following the Deepwater Horizon Oil Spill Disaster in 2010, regulators and operators increased their focus on blowout contingency planning with significant emphasis on well capping, relief well drilling and dynamic kill operations. In particular, Norwegian drilling and well regulations now states that a permit for drilling can only be granted if well control can be regained by intervention with just 1 relief well.
This case study demonstrates how single relief well contingency can be achieved using a Relief Well Injection Spool (RWIS) - a piece of specialist subsea equipment that enables operators to stop a blowout from a prolific reservoir safely and efficiently, by increasing the pump rate of kill mud into the blowing well.
In being able to kill a blowing well with just 1 relief well as opposed to 4 intercepts, this operator experienced significant cost savings, a reduction in resources required and made zero modifications to the size of the completion bore as direct impacts of using the RWIS.
