What iReservoir.com does

iReservoir.com Inc. is a privately-held, Littleton, Colorado-based specialist consulting firm founded in 2000 that provides integrated reservoir characterization and simulation services to oil and gas companies. Its core offer combines geology, petrophysics, geophysics, geomodeling, and reservoir engineering into non-sequential, multidisciplinary integrated studies covering conventional clastic and carbonate fields, fractured reservoirs, heavy oil, and unconventional tight and shale plays. The firm has completed over 220 reservoir studies globally and has a 17-year track record of distinctive project experience in basins spanning the US Rocky Mountains, Permian, Gulf of Mexico, East Texas, Louisiana, Oklahoma, Alaska, the UK and Norwegian North Sea, the Middle East, Africa, South America, Mexico, Indonesia, China, and Russia. Revenue is generated through project-based professional-services engagements with enterprise oil and gas clients, supplemented by technical training courses for industry professionals.

The firm's technology centerpiece is the proprietary Echelon GPU Flow Simulator, an ultrafast massively parallel reservoir simulator co-developed with Stone Ridge Technology that is capable of modeling 25-million-cell dual-porosity unconventional reservoirs. iReservoir uses a "Best of Class" multi-vendor software stack with proprietary in-house applications rather than a single-platform solution, and it emphasizes calibration, quality control, and feasibility throughout. The go-to-market is sales-led direct consulting, supported by top-of-funnel thought leadership at SPE, SEG, EAGE, and URTeC conferences and by published case studies. Named enterprise customers include EnCana, Amerada Hess, Marathon Oil, Repsol-YPF, and Schlumberger.

Core offering

iReservoir.com provides world-class consulting services in reservoir characterization and simulation to oil and gas companies using integrated geoscience and engineering workflows. The company combines geology, petrophysics, geophysics, geomodeling, and reservoir engineering into interdisciplinary reservoir studies, supporting both conventional and unconventional resources including tight gas, shale, naturally fractured, heavy oil, clastic, and carbonate reservoirs. A core technology asset is the proprietary Echelon GPU Flow Simulator, an ultrafast massively parallel GPU reservoir simulator developed for modeling 25 million cell dual porosity unconventional reservoirs.

Product overview

iReservoir.com provides world-class consulting services in reservoir characterization and simulation to oil and gas companies. Their portfolio centers on integrated multidisciplinary studies combining geology, petrophysics, geophysics, geomodeling, and reservoir engineering. The core technology offering is the Echelon GPU Flow Simulator, an ultrafast massively parallel GPU reservoir simulator capable of modeling 25 million cell dual porosity unconventional reservoirs. The company specializes in unconventional resources, fractured reservoirs, tight gas sandstones, and conventional oil and gas fields, offering services from seismic-derived facies probabilities through static geomodeling to dynamic flow simulation. They utilize a non-sequential integration approach with 'Best of Class' software for each discipline rather than single-platform solutions.
