Meeting the challenges of low cost rig-less decommisioning of platform wells

With the rising number of North Sea fields reaching the end of their useful economic life, an increasing number of operators are faced with well decommissioning projects. Operators have identified rig-less decommissioning of wells as a major cost saving initiative, but this involves technical challenges arising from the absence of a rig and many platforms having limited crane facilities. ... [read more]
