Multistage Fracturing Software

pengtools optiFracMS

optiFracMS is a software to optimize the number of hydraulic fractures in horizontal well ^[1].

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

optiFracMS is available online at www.pengtools.com.

Typical applications

• Multistage Fracturing Design
  • How many fractures are required to maximize production?
    • Number of fractures, n.
  • What fractures geometry is required to maximize production?
    • Dimensionless Fracture conductivity, C_fD .
    • Fracture half length, X_f .
    • Fracture width, w .
    • Fracture penetration, I_x .
  • What would be the optimal productivity index?
    • Dimensionless productivity index, J_D .
• Multistage Post fracture performance reviews
  • Find out how far your well's productivity from where it should be (from the optimum)
• Multistage Fracturing Sensitivity Studies and Benchmarking

Main features

• Plot of J_D as a function of n and N_p as parameter.
• Plot of J_D as a function of N_p showing the width constraint influence.
• Plot of J_D and w_f as a function of n for the given N_p .
• Plot of J_D as a function of C_fD for the given n.
• Design optimization curves which corresponds to the maximum J_D values for different N_p and n.
• Optimum number of fractures n and well J_D.
• Practical constrains envelope – minimum fracture width and choke skin effect.
• Sensitivity for the different from the optimal n, X_f, I_x, C_fD, w_f.
• Hydraulic fracturing proppant catalog with the predefined proppant properties.
