How it Works

The following is a condensed explanation of how ReservoirGrail can help you find millions of barrels of previously overlooked reserves. The three images below represent three major stages of simulation that ReservoirGrail undergoes in a typical reservoir modeling project.

ReservoirGrail employs a unique patented approach called Time Dynamic Volumetric Balancing © (TDVB) to model the migration of reservoir fluids (oil, gas, and water) through time. Unlike traditional flow simulators (Darcy’s Law simulators), ReservoirGrail does not carry the burden of solving highly non-linear equations. Instead, using the minimal data input necessary to calculate reservoir volumes (thickness, porosity, and saturations), ReservoirGrail creates a model of the original conditions of your reservoir as seen below.

  • OHIP MAP

    The flowpath map (drainage function) for each well is computed using your existing map that best depicts your reservoir and how it will behave. This map is often based on net sand, seismic attributes, phi-h, or another reservoir parameter that best depicts the quality of your reservoir.

  • DRAINAGE MAP

    ReservoirGrail’s TDVB technology models the reservoir production using the drainage functions and the historical production data. For each production reporting time period, a map of the reservoir fluids is produced. The current conditions map (CHIP) is often the final output.
