Carina Sondermann is pursuing her D.Sc. Degree in Mechanical Engineering at the Universidade Federal do Rio de Janeiro (COPPE/UFRJ), in Brazil. She is a Mechanical Engineer and received her M.Sc. Degree in Mechanical Engineering from the same institution.

Carina’s research interests are fluid mechanics with emphasis on multiphase flow, pipe flow modeling and numerical simulation.

 

Carina is currently studying and developing a numerical strategy based on a transient one-dimensional approach, known as slug capturing, that can reproduce the physics of the intermittent two-phase flow. As part of this research, Carina performed an experimental campaign as a Visiting Scholar at The University of Tulsa to use as validation of the final slug capturing code. This research aims to assist the oil and gas industries in understanding the phenomena, as well as, improving the accuracy of slug flow simulations.

Robert Sutton

Robert Sutton received a BS degree in Petroleum Engineering from Marietta College in May, 1978 and began work with Marathon Oil Company in Lafayette, LA in June.  Concurrent with full time work at Marathon, Rob pursued a MS degree in Petroleum Engineering at The University of Southwestern Louisiana (now University of Louisiana at Lafayette) which was received in December, 1983.

While in Lafayette with Marathon, Rob worked in the Operations (offshore, well completions, workovers, surveys & stimulation), Reservoir (reserve evaluations, production forecasting and economics) and Budget Control (district office budget administration) Departments.  In 1985 he transferred to Marathon’s Denver Research Center and worked in the Applied Technology Group where he worked with black oil and compositional reservoir models and EOS programs.  Rob also became the Marathon contact for industry programs at The University of Tulsa (TUFFP, TUPDP and later TUHWALP).  An interest in multiphase flow led Rob to develop in-house software for use in the areas of Nodal Analysis, gas well unloading, erosional velocity, and oil-gas-water PVT evaluation.  In 2001, the technology group relocated to Houston from Denver where Rob remained active in applied technology support.  Rob retired from Marathon on Jan.1, 2014 after 35.5 years of service.  He also received the 2014 SPE Production sand Operations award that year.

Rob remains active in the industry serving on various SPE committees, ALRDC and is a member of the API 19G Task Group for gas lift recommended practices.  He is a visiting scholar at the McDougall School of Petroleum Engineering for The University of Tulsa.  He is also active as a petroleum consultant.  Rob has participated in authoring 29 SPE papers with 10 published in SPE Journals.  He contributed to the oil PVT chapter in the SPE Petroleum Engineering Handbook and a chapter in the book titled Gas Well Deliquification, 2nd Ed.  Rob was a SPE distinguished lecturer during the years 2012-13 and 2015-16.  He has also given numerous talks on horizontal well performance and liquid loading at various ALRDC Gas Well Deliquification Workshop and SPE meetings.
