... development in the North Sea. The proposed system has an electrohydraulic control module, provided by Schlumberger, mounted on a subsea production tree, which provides complete control and monitoring of the intelligent well independent from the tree control system. This approach allows the intelligent well...

... through bore Xmas Trees and cluster well manifolds Chokes and subsea control pods are to be housed in independent, diverless retrievable modules fitted in the manifolds, thus allowing the use of a simple tree design Each manifold choke and subsea control module will service two wells, minimising the size...
