OptiFracMS

Brief

optiFracMS is a hydraulic fracture design optimization tool.

For the given set of reservoir and propane properties it calculates maximum achievable well productivity index and required fracture geometry.

Typical applications

• Single Well Fracture Design
• Design Sensitivity Studies and Benchmarking
• Optimum fracture design parameters determination:
  • Dimensionless productivity index, J_D .
  • Dimensionless Fracture conductivity, C_fD .
  • Fracture half length, X_f .
  • Fracture width, w .
  • Fracture penetration, I_x .

Main features

• Plot of J_D as a function of C_fD and I_x as parameter.
• Plot of J_D as a function of C_fD and N_p as parameter.
• Design optimization curve which corresponds to the maximum J_D values for different N_p.
• Design Optimum Point at which the dimensionless productivity index, J_D, is maximized for the given proppant, fracture and reservoir parameters.
• Physical constraints envelope.
• Proppant library with predefined proppant properties.
• Users Data Worksheet for benchmarking vs actual.

Interface features
