Deepest RMR® in the North Sea

How a major operator in the North Sea solved the issues they were having with the design of the well casing program when planning to drill a subsea well.

When a major operator was facing issues with the design of the well casing program in the North Sea, Enhanced Drilling helped solve this challenge by providing a RMR® solution to set the deepest 20” casing and longest 26” section on the Ormen Lange Field in the North Sea.

Cost savings whilst zero discharge to seabed


The RMR® solution gave the operator tophole stability whilst saving both costs and discharge to seabed due to the riserless drilling with mud returns.

Harsh weather conditions requires innovative solutions

Although the operator considered a pump and discharge method, this option was dismissed due to the harsh weather conditions in the North Sea.
