James R. Gilman, Director of Engineering
  • Chemical Engineering, M.S., Colorado School of Mines, 1983
  • Chemical Engineering, B.S., Montana State University, 1978
Jim has over 22 years experience in the petroleum industry. Jim's expertise includes specialization in the area of application and development of numerical simulators for fluid flow in petroleum reservoirs. He was a co-developer of Marathon Oil Company's 3-D, 3-phase simulator for naturally fractured reservoirs and was instrumental in testing and debugging of the dual-porosity versions of the commercial black-oil and compositional simulators for Marathon's applications. In addition to simulation expertise, Jim's work at Marathon Oil Company's Technology Center involved company-wide training and consultation in the areas of reservoir engineering, reservoir simulation, naturally fractured reservoirs, horizontal wells and production risk/uncertainty analysis. He was most recently Manager of Reservoir and Well Performance, a multi-disciplinary organization involved in 3-D geologic modeling, laboratory special core analysis, reservoir simulation and general reservoir engineering. Jim has authored or co-authored over a dozen articles primarily dealing with naturally fractured reservoirs or horizontal wells. He was a member of the SPE Editorial Review Committee from 1987-2000 and most recently served as an Executive Editor for SPE Reservoir Evaluation and Engineering. He served as Chairman of the Twelfth SPE Symposium on Reservoir Simulation (1993) and on the program committees for the 1991 and 1997 symposiums.

Jim is a registered PE, and a member of the SPE, API, and AICHE.

Reinaldo J. Michelena, Ph.D, Director of Geophysical Technology
  • Geophysics, Ph.D., Stanford University, 1993
  • Geophysics, M.S., Stanford University, 1990
  • Physics, B.S., Universidad Simón Bolívar, Caracas, Venezuela, 1984
Reinaldo has spent fifteen years dedicated to research, development, and application of innovative seismic methods to help reservoir delineation and characterization, from programming and testing of novel algorithms to integrated interpretation of field data results. He has demonstrated the ability to plan, initiate, and complete multidisciplinary, complex technical projects.

In 1991 he worked at Amoco Production Company, Tulsa, OK as a visiting Scientist in the Tulsa Research Laboratory where he developed a code to do kinematic ray tracing in transversely isotropic media.

During 1993 - 2000 he worked at PDVSA- Intevep, Research and Technological Support Center where he served as Project Leader, Seismic Techniques for Reservoir Characterization. He was involved in all stages of the work performed in the area of multicomponent surface seismic. He successfully applied innovative ideas for the integrated interpretation of 3C data using structural, lithological, production, and fracture information. He also developed new methods to estimate fracture orientation from 2D and 3D converted wave data. The results of these methods were compared successfully with results obtained from azimuthal AVO analysis of P-wave data. Horizontal well trajectories where designed using these results.

In 2000 he spent seven months as a visiting scientist at CGG Americas Inc., Houston, TX, where he developed a method to perform automatic correlations between PP and PS records. This method was tested successfully with 3C data from the Orinoco heavy Oil Belt.

From 2001- 2003 he worked for PDVSA, (Intevep, Research and Technological Support Center) as a Senior Scientist for Reservoir Delineation and Characterization where he led a multidisciplinary team of geologists, geochemists, geophysicists, petrophysicists, reservoir engineers, and geostatisticians.

Reinaldo is principal author or coauthor of over fifty papers published in internationally recognized journals and proceedings of national and international congresses. He has been involved in activities at a number of academic institutions and is a member of the Society of Exploration Geophysicists (SEG), American Association of Petroleum Geologists (AAPG), and the Society of Petroleum Engineers (SPE). He has been actively involved in all three societies, including Associate Editor of the Journal of Geophysics in the area of seismic inversion from 1994 - 2001.
