MFrac

MFrac is a comprehensive design and evaluation simulator containing a variety of options including three-dimensional fracture geometry and integrated acid fracturing solutions. Fully coupled proppant transport and heat transfer routines, together with a flexible user interface and object oriented development approach, permit use of the program for fracture design, as well as treatment analysis. MFrac is the calculation engine for real-time and replay fracture simulation. When operating in this manner, the program works in conjunction with our real-time data acquisition and display program, MView.

Capabilities

  • Automatically design a pumping schedule to achieve a desired fracture length and conductivity
  • Parametric studies, what-if scenarios
  • Geometry and design optimization for proppant, acid and foam treatments
  • Pressure History matching and model calibration in real-time replay
  • Perform analyses to anticipate fracture behavior (e.g., fracture growth, efficiency, pressure decline, etc.)
  • Use MFrac in conjunction with MProd and MNpv to perform fracture optimization studies

Features

  • Real-time/replay capabilities
  • Heat transfer in the wellbore and fracture
  • Acid fracturing
  • Rigorous deviated wellbore model (horizontal wells)
  • Proppant Transport
  • Perforation Erosion
  • Compressible fluids (foam treatment schedule)
  • Near wellbore pressure effects (tortuosity)
  • Multilayer fracturing (limited entry)
  • Comprehensive proppant, fluid, acid, tubing and rock databases
  • Multiple fractures (parallel or dendritic)
  • Options for 2D and horizontal fractures
  • State-of-the-art fracture tip effects (including critical stress)
  • Time and stage dependent leakoff
  • Three dimensional plots
  • Couple these features with the ability to automatically design conventional, TSO’s and FRAC-PACK’s (high conductivity fractures), the industry now has an engineering tool to diagnose, analyze and truly understand the fracturing process.

Integration

During real-time or replay analyses, MFrac receives the simulation input data from MView. This data can include the acquired parameters: pump rate, bottomhole and surface pressures, proppant concentration, and nitrogen or CO2 injection rates versus time.

The minifrac results from MinFrac can then be used in MFrac to calibrate the stresses, fracture model, fracture efficiency, pad volume, etc. prior to the actual pumping of the main treatment.
