Construction and Validation of an Integrated 3D Reservoir Characterization Geomodel for Reservoir Management at Seminole San Andres Unit

Dynamic Ranking of Reservoir Uncertainty using Streamlines

Hart's E&Pnet Article featuring iReservoir

Oil and Gas asset management study requires an interdisciplinary, integrated approach to assess field development opportunities. iReservoir.com is unique in our ability to offer truly integrated reservoir characterization, reservoir engineering and modeling from core and analog outcrop work, seismic inversion, static modeling, upscaling, reservoir simulation, on through to uncertainty analyses and operational recommendations.

Our shop includes expertise in geology, petrophysics, geophysics, and reservoir engineering. Some of the types of analysis we have performed include:

• Sedimentologic-stratigraphic consulting for both carbonates and clastics.
• Petrophysics, including normalization, permeability-prediction, and facies prediction.
• Seismic inversion (both for exploration and development applications), also feeding into high-resolution velocity fields for reservoir-scale time-depth conversion.
• Static reservoir model construction, with or without up-scaling using geostatistical methods which span the gamut from cell-based to object-oriented, incorporating facies indicator simulation if possible.
• Simulation ranging from small, conceptual models to full-field multiphase problems in naturally fractured reservoirs. Streamline simulation is also applied for specific multi-realization uncertainty comparisons. We also have expertise in conventional reservoir engineering techniques.

Our US experience base covers the Rocky Mountain region, the Permian basin, the Gulf of Mexico, East Texas, Louisiana, Oklahoma, and Alaska.

Our international experience base covers the UK and Norwegian North Sea, Middle East, North Africa, West Africa, South America, Mexico, Indonesia, China, and Russia.

We have applied our domain expertise to develop various technical software for petrophysics/rock-physics forward modeling and seismic attribute evaluation. We have also developed a software product called "iProject" which is a Web-based reservoir characterization collaborative environment. This proprietary software adds efficiency and saves time in project establishment, collaboration, QC (of data and interim deliverables), and archiving. We have completed projects using this software with international clients to remotely assemble and monitor reservoir-modeling projects.
