John HornbrookJohn W. Hornbrook joined DeGolyer and MacNaughton in 2002 with wide-ranging practical and educational qualifications and serves as Manager of the Reservoir Studies Division. He is responsible for management of projects around the world, including field development projects in Algeria, Russia, and Peru, large-scale integrated studies in Kuwait, and simulation-based studies in the Gulf of Mexico. Hornbrook's experience includes field development studies, probabilistic analysis, reserves estimation, property valuation, well test design and analysis, gas storage assessment, and analysis of improved oil recovery mechanisms. His domestic expertise ranges from U.S. onshore fields, the shelf and deepwater Gulf of Mexico, and Prudhoe Bay, Alaska, and in global venues that include the Middle East, Western and Eastern Siberia, the Gulf of Thailand, the North Sea, Australia, Oman, and offshore Nigeria. He is experienced in oil and gas, heavy oil, geothermal, and coal bed methane applications.

For DeGolyer and MacNaughton, he has worked many projects in Western Siberia, ranging from reservoir modeling to improve field performance to full-field geologic and simulation modeling for field development planning. In Eastern Siberia, he has developed full-field geologic and simulation models in complex reservoirs to evaluate field development planning options and to assess subsurface uncertainty. He has also made use of integrated simulation modeling to assist with portfolio management of multiple fields across Russia and has applied geologic and simulation modeling techniques to assess reserves in complex reservoirs. He has simulated thermal recovery processes in a heavy oil field in Oman and has assisted with reserves assessments.

Prior to joining DeGolyer and MacNaughton, he worked with one of the world's largest petroleum corporations and then with a consulting firm on a variety of domestic and international projects. Hornbrook gained experience in development modeling in the Gulf of Mexico, the continental U.S., and the Gulf of Thailand and performed modeling in support of an arbitration involving a multi-reservoir field in the North Sea. With BP Exploration from 1994 to 1997, Hornbrook focused on development of the Prudhoe Bay reservoir, performing analyses for the Miscible Gas Project to determine optimal development and operational strategies.

Hornbrook received a B.S. degree in petroleum engineering from the University of Tulsa in 1986. From Stanford University he earned an M.S. degree in 1991 and a Ph.D. degree in 1994 in petroleum engineering. He received numerous educational honors and has contributed technical articles to industry journals and educational publications. Among his professional affiliations, Hornbrook is a member of the Society of Petroleum Engineers, serves as technical editor for the "SPE Reservoir Evaluation & Engineering" magazine, and is a registered professional engineer in the state of Texas. Hornbrook was elected Vice President of DeGolyer and MacNaughton in 2004 and Senior Vice President in 2010.
