Casing/cementing/zonal isolation
Offline cementing was used to develop a marginal field in Malaysia. The development was made possible through distinctive wellhead technology and good operational planning.
This paper describes the path to implementation of full casing rotation during primary cementing jobs.

In the complete paper, a novel system that uses engineered features of permeable polymeric shell walls for the controlled release of encapsulated cargo is described. -
This year, excellent papers have been presented, augmenting our knowledge and responding to the challenges of complex wells and efficiency requirements. At the same time as we “Strengthen the Core,” we continue to focus on design, delivery, and evaluation of cementing operations.

This case study discusses the methodology that underlies the successful determination of the depths and the radial locations in the outer casing strings of multiple leaks in an offshore well.
-
This paper describes the mobilization of a snubbing unit and blowout preventer (BOP) stack in the Middle East that enabled a well with an underground blowout and surface broaching to be brought under control within a short time.
