A New Insulation Technology: Prediction vs. Results From the First Field Installation

Abstract

Insulation is a critical aspect of offshore production systems, particularly in deeper waters where low ambient temperatures must be addressed and accommodated. The problems are normally associated with the effects on the flow stream when heat is lost to the surrounding environment. However, there are some situations where it is not the effects on the production stream from heat loss that is the problem, but the effects on the surrounding environment that creates the problem. This paper primarily focuses on the situation where reservoir heat in a production stream creates a technical problem in the area surrounding a well bore. The paper then presents a new insulation technology that was evaluated as part of the solution and discusses the successful outcome. The results are then used to address the potential utilization of this new technology for other flow assurance related heat control applications where the retention of heat in the production stream is desired, such as the need for insulating subsea flow lines, jumpers, manifolds, xmas trees, production risers and other associated production equipment.
