  • 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.

Huabing Wang, Ph.D, Reservoir Engineer
  • Chemical Engineering, Ph.D., University of Utah, 2008
  • Chemical Engineering, M.S., Brigham Young University, 2003
  • Chemical Engineering, B.S., Beijing University of Chemical Technology, 1997

Huabing joined iReservoir in 2008 after completing his Ph.D. at the University of Utah, Salt Lake City. His Ph.D. thesis focused on multiphase, multiscale simulation of fractured reservoirs completed at the Petroleum Research Center in the University of Utah. Huabing developed an expertise in modeling the multiphase fluid flow in fractured petroleum reservoirs using numerical methods and integrated fractured reservoir studies.

Huabing’s research contributed to a team that is developing the next generation control-volume-finite-element (CVFE) based reservoir simulators which is funded and supported by the U.S Department of Energy. On a project-specific level, he is experienced with modeling and simulating basement fractured reservoirs: either from seismic to sub-seismic feature field model, or from core sample and single seismic feature to fault-zone model. With his background, experience and research in conventional thermodynamic phase equilibriums, Huabing has been able to model immiscible and partially-miscible oil/water interfacial properties at a molecular level using quantum statistical methods. His work may help future researchers answer questions about multiphase fluid flow in reservoirs. During his research and education, Huabing has become proficient with various computer languages to program scientific computations, visualization and interface development.

Huabing is a member of the SPE, AAPG, SEG and AIChE.
