The selection and installation of the completion in a new well is fundamental in the determination of the productivity and ultimate value of the asset. Intervention operations will determine the cost and value of operating and abandoning the asset. This session will focus on the integrity and durability of the assets. We will see how through-tubing technologies can be used in abandonment operations and how the durability of well heads can be improved through new designs which will reduce fatigue. Also, we will discuss how newly developed sand-screens can improve durability and integrity of the gravel pack and the well.
