Research Highlight

We have recently developed and proven the best fracture modeling tool for simulating any and all types of fractures (hydraulic and natural) to enhance your existing reservoir models to drastically improve predictability and optimization/development strategies for both primary and enhanced oil recovery applications. Having this capability is critical because fractures can dominate the results seen in the field. This system can be swiftly integrated into existing frameworks for all reservoirs to perform more predictive sensitivity analyses, more representative history matching, and accurate production forecasting. This physics backed system essentially incorporates any fracture framework (using real field data or understandings) and is called the Embedded Discrete Fracture Model (EDFM).

This innovative software was developed in conjunction with third-party reservoir simulators such, as CMG, ECLIPSE and tNavigator. Using this tool can easily, efficiently, and accurately simulate field results with any simple and complex hydraulic/natural fractures, which improves accuracy and reduces computational expense and your time. Also of strong interest, we can transfer your existing fracture geometry models from third-party fracture simulators, such as Kinetix, Gohfer and Stimplan, to your current third-party reservoir simulators.

Research Projects

  • Provides multiple History Matching solutions in few hours including natural fractures impact.
  • Reduces subsurface uncertainties (e.g. effective fracture and matrix properties) and estimates production forecast reliably.
  • Provide assessment for infill well placement and optimal well spacing more accurately.
