pengtools optiFracMS

Category: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.

Typical applications

• Multi Stage Fracture Design
• Design Sensitivity Studies and Benchmarking
• Optimum fracture design parameters determination:
  • Number of fractures, n.
  • 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 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.
• Proppant library with the predefined proppant properties.

Interface features
