Brief

optiFracMS is a tool to optimize the number of hydraulic fractures in horizontal well.

For the given set of reservoir properties and the proppant mass it calculates optimal number of transverse hydraulic fractures and required fractures geometry to maximize well productivity index.

pengtools optiFracMS

Typical applications

  • Multi Stage Fracture Design
  • Design Sensitivity Studies and Benchmarking
  • Optimum fracture design parameters determination:
    • Number of fractures, n.
    • Dimensionless productivity index, JD .
    • Dimensionless Fracture conductivity, CfD .
    • Fracture half length, Xf .
    • Fracture width, w .
    • Fracture penetration, Ix .

Main features

  • Plot of JD as a function of n and Np as parameter.
  • Plot of JD as a function of Np showing the width constraint influence.
  • Plot of JD and wf as a function of n for the given Np .
  • Plot of JD as a function of CfD for the given n.
  • Design optimization curves which corresponds to the maximum JD values for different Np and n.
  • Optimum number of fractures n and well JD.
  • Practical constrains envelope – minimum fracture width and choke skin effect.
  • Sensitivity for the different from the optimal n, Xf, Ix, CfD, wf.
  • Proppant library with the predefined proppant properties.
