Managing Subsurface Uncertainties in Facilities Design
Bridging the gap between facilities and reservoir engineers is critical in designing production systems that are flexible enough to allow a spectrum of reservoir feed conditions to be accommodated over the life cycle of the field. Although subsurface uncertainties cannot be eliminated, they can be managed.
A Strategic Shift in Well Abandonment Services
Global decommissioning projects are ramping up as many installations near the end of their life cycle. Many operators are now planning for major removal projects. Changes in technology and regulations have caused operators to make significant shifts in well abandonment operations.
Rapid Rise Hydrocarbon Fires: An Engineering Perspective
Hydrocarbon fires present facilities engineers with a special set of protection issues compared with those in which the fuel source is wood or building materials. Hydrocarbon fires behave differently from cellulosic fires. Fire protection products for structures and equipment must meet specific approvals.

Case Study—Calcium-Carbonate-Scale Inhibitor Performance Degradation Because of H2SScavenger Injection in Semoga field
M. Sumestry and H. Tedjawidjaja
The second in a two-part series that provides a methodology for optimizing the design of a separator using computational fluid dynamics. The paper identifies the process used and supports the modeling with a case study. The series began with a paper published in the December 2012 peer-reviewed section of Oil and Gas Facilities.
Design of Gelled Fluid for Debris Removal in Subsea Pipeline
C. Misra, A. Danait, and L. Salgaonkar
Tdescribes the impact of other chemicals—hydrogen sulfide scavengers in this case—on the effectiveness of scale inhibitors. This paper reminds us that the production system must be treated as a complete system, and that changes to one part may severely impact another.
CFD-Based Study of an Oilfield Separator—Part II: An Optimum Design
A.P. Laleh, W.Y. Svrcek, and W.D. Monnery
This paper moves to the Arctic environment and discusses the issues related to ice movement and potential impact with trenched pipelines. I was surprised by the depth of gouging that can take place in this environment and the amount of protection required for the pipelines.
Trenching of Pipelines for Protection in Ice Environments
M. Paulin, D. Humby, J. Cocker, and G. Lanan
This paper discusses the design and use of gelled fluid for debris removal in subsea pipelines when standard pigging methods are not viable. This paper also highlights the need to understand the chemicals used in a pipeline system.
