Managing Risks in an EPCIC Subsea Boosting Application

William Power, Senior Project Engineer; Murphy Oil

This presentation will discuss the managing of risk through Strategic Alliance EPCIC contracting for a brownfield subsea boosting enhanced oil recovery project in a low commodity price environment. It also will review the execution strategy and implementation of lessons learned from past projects that challenge conventional GoM execution models practiced during more favorable economic conditions.

Decommissioning the Deimos Subsea Field with Development in Mind

Bryan Coward, Subsea Engineer; Shell

In 2016, Shell decommissioned the Deimos Subsea Field with an eye towards cost optimization and preservation for future tiebacks. Utilizing methods not normally associated with abandonment, the team was able to collect flowline integrity data and retain future utility, all while efficiently decommissioning the system at low cost. This presentation centers around the techniques and decisions made to deliver long-term value from a deepwater decommissioning project in the Gulf of Mexico.

Bryan Coward is a Subsea Engineer for Shell supporting subsea assets in the Mars Basin. His experience is primarily in the areas of production surveillance, integrity and brownfield project execution. Bryan graduated from West Point in 2007 and has five years industry experience with Shell supporting various assets across the Gulf of Mexico.

Challenge of Positive Integrity Verification in Inaccessible Areas

Caleb Wells, Shell Subsea Engineer; Shell Exploration & Production Company

Shell identified an area of external corrosion on two risers inside J-Tubes on a high GOR subsea tieback that could not be inspected by existing UT equipment. Shell worked with vendors to develop three serial number one devices for the J-Tube window cutting, riser wall thickness measurement in a tight annulus, and Splashtron removal, in order to prove that the system had sufficient remaining wall thickness to continue operating. This presentation will discuss the integrity verification process.

Caleb Wells is a Shell Subsea Engineer based in New Orleans with five years of industry experience focused on subsea surveillance and brownfield projects.
