iReservoir provides world-class consulting services in reservoir characterization and simulation to oil and gas companies using state-of-the-art geoscience and engineering technologies. We are unique in our ability to offer truly integrated reservoir characterization, from core and analog field work, advanced petrophysical modeling, calibrated seismic inversion and facies mapping, seismic based fracture mapping, geological modeling for matrix and fractures, reservoir engineering and simulation, reservoir management, EOR/IOR, and unconventional resources, on through uncertainty analyses and operational recommendations. iReservoir has unparalleled experience in a large variety of geologic scenarios, from tight-oil and tight gas unconventional reservoirs to prolific naturally fractured systems. We have expertise in analysis and simulation of recovery processes methods ranging from depletion to aquifer drive, water injection, gravity drainage and various EOR. Our proprietary technologies are distinctive. For petrophysical modeling, we offer iMineralysis®, a nonlinear optimization tool that can tackle the most challenging mineral and fluid compositions. In the seismic technology, we offer innovative and well tested technologies to characterize facies and natural fractures and use these results to constrain matrix and discrete fracture models. For flow simulation, we offer a newly developed ultrafast massively parallel GPU simulator (Echelon®) that can model very large single- and dual-permeability models.
