Recycling of Produced Condensate Through Deepwater GOM Subsea Gas Production Lines to Maintain
Hydrate Inhibitor Effectiveness
David A. Shumbera, Senior Advisor - Reservoir and Petroleum Engineering; Eni US Operating Co. Inc.
When water production started from the main gas-producing well, LDHI was required to produce the Longhorn feld, a deepwater
GOM gas feld consisting of 4 subsea wells tied back 19 miles to a processing platform. When associated condensate production
from the other gas wells declined later in feld life, the water-producing, high-rate gas well did not produce enough condensate to
maintain the water cut of the main subsea fow line below the maximum water cut limit for LDHI hydrate-treating effectiveness.
To allow continued feld production, injection of produced condensate into the main producing subsea fowline at the subsea
manifold was initiated and has proven successful in maintaining LDHI effectiveness. This is the frst known installation and actual
operation world-wide of a produced condensate recycling system to reduce water cut in a producing subsea fowline to allow
continued LDHI hydrate-treating effectiveness.
David A. Shumbera is currently a Senior Reservoir and Petroleum Engineering Advisor with Eni US Operating Co. Inc. in Houston, Texas responsible
for well/reservoir management, production optimization and well/reservoir integrity for Eni’s deepwater GOM-operated assets. He has 36 years of
Reservoir and Petroleum Engineering experience ( 21 years of which are in deepwater GOM-operated feld development and reservoir management). He
has been with Eni for 18 years with previous positions with Atlantic Richfeld (ARCO) and Occidental. He is a graduate of Texas A&M University with a
BS and MS in Chemical Engineering.
Neptune Flowline Gas Circulation
Rodney Hichens, Senior Process Engineer; BHP Billiton
A cost effective fowline gas-lift solution was successfully implemented during 2015 for the Neptune Deepwater TLP. This
project required only minor topsides piping modifcations, and enabled continuous gas circulation around a fowline loop. This
modifcation has proven essential to sustaining the life of the Neptune feld by ensuring successful feld restarts, maintaining fow
stability and maximizing well deliverability.
Rodney Hichens is a Senior Process Engineer for BHP Billiton, supporting the GOM Production Unit. Rodney was the Start-Up and Commissioning
Engineer for the Neptune Gas Circulation Project.
Asphaltene Management in the Deepwater Thunder Horse Field
Amber Mees, Production Engineer; BP
BP’s Thunder Horse feld has been challenged by asphaltene deposition in wells, subsea infrastructure, and topsides throughout
its eight-year history. In order to reduce production deferrals due to asphaltenes, a system-wide asphaltene monitoring and
remediation program was developed and has become critical to maintaining more than 50% of total production.
Amber Mees is a petroleum engineer with 10 years of experience at BP. She has worked in deepwater Gulf of Mexico operations for seven years,
including her current role supporting BP’s Thunder Horse facility. Prior to her deepwater roles, Mees was a production engineer for gas operations in
Texas, Colorado as well as the North Sea, UK. Amber received her Bachelors Degree in Chemical Engineering from Texas A&M in 2005.
