The development of innovative technologies and the effective application of late-stage intervention and abandonment systems in the oil and gas industry have resulted in cost savings and an increased standard of safety. This paper examines the successes of fit-for-purpose systems specifically designed for operations on load bearing offshore platform projects in an efficient manner.

To effectively address the market, a new system for completing interventions and abandonment operations was needed. Subsequently, a system was designed which incorporates capabilities associated with Jack Up rigs along with the quick mobilization and set up of a crane assisted rigless unit. This solution has been utilized in offshore campaigns that include all phases of abandonment operations including well diagnostics, reservoir isolation, tubular retrieval, fishing and section milling.

This paper will review the capabilities of the system along with case studies which highlight the versatility and adaptability of the system which provides an integrated solution package to the client. The system which includes a Pulling and Jacking unit also incorporates all ancillary equipment necessary to proficiently intervene and permanently abandon offshore wells. These case studies will discuss the planned parameters, examine the operations, and review the lessons learned from the projects.
