Drilling from a Deepwater Spar: Innovative Adaptation of Existing Single Barrier Riser at Devil’s Tower
Bill Cowan, Subsea Advisor; ENI U.S. Operating Co.
The production risers at Devil’s Tower are single-barrier design, originally meant for reentry and workover but not for drilling. An
innovative riser wear liner, used with a carefully conceived drilling program and riser monitoring program, allowed for a safe and
successful sidetrack of one of the system wells.
Bill is the Subsea Engineering Advisor for ENI Petroleum, the U.S. operating company of ENI SpA. of Italy. Bill has been with ENI for 14 years, providing
consultative support on subsea wellheads, trees, and BOPs for their Well Operations Department. He has been in the oil and gas business for 43
years, starting work in 1973 with what was then the National Supply Co. (now AKER Solutions). Altogether he has 23 years working in product design
and manufacturing and 20 years working for operators. Bill has worked through the years in API standardization, serving on groups writing the original
editions of 17A, 17D, 17G, 17W, and 16Q. He also is the ENI representative on the re-write of API Std 53 for BOPs. Bill holds 11 U.S. patents for oilfeld
equipment. He is a member of ASME, and is a registered professional engineer in Texas. He holds a BSME from Texas Tech University and a Master

Thunder Horse Water Injection: Start Up and Lessons Learned
Carlos Stewart, Petroleum Engineer; BP
Project and start up challenges and lessons learned implementing a water injection project on a brown feld development.
Challenges and lessons learned range from equipment preservation, facility SIMOPS, and injection well remediation, to initial
start-up issues with injection chokes.
Carlos Stewart is a Petroleum Engineer at BP with 11+ years of PE experience, 6 years working with water injection in the Gulf of Mexico. Carlos
supported the Thunder Horse Water Injection project though the project execution phase starting in 2014 and continues to support water injection
operations post transition to the operating phase.
Brownfeld Projects Execution/Lessons Learned From a Third Party Host
Clay Coffey, Project Engineer; Noble Energy
The current commodity climate is promoting subsea tiebacks as frontrunners for viable upcoming developments. In late 2013,
Noble Energy sanctioned two long distance deepwater tieback projects: Big Bend/Dantzler and Gunfint. These developments
gathered production to foating facilities owned by one company and operated by another company. The presentation will
compare and contrast the interfaces between the multiple parties and show how the varied experience levels, operating
philosophies, and execution approaches of the companies infuenced the outcome of the projects while at the same time dealing
with declining commodity prices. Execution and operating lessons learned from the projects will be presented to aid others in
planning and executing tiebacks to third party hosts.
Clay Coffey is a deepwater project engineer within Noble Energy’s Major Projects Group. He has worked on the planning and execution of the subsea
and topsides portions of the Gunfint tieback over the last two years. Clay is a veteran of the U.S. Navy’s submarine force and holds a Bachelor of
Science degree in Petroleum Engineering from the University of Texas at Austin.
