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.
The RMR® solution gave the operator tophole stability whilst saving both costs and discharge to seabed due to the riserless drilling with mud returns.
Although the operator considered a pump and discharge method, this option was dismissed due to the harsh weather conditions in the North Sea.
