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.
