Brief
optiFrac is a single well fracture design optimization tool.
For the given set of reservoir and proppant properties optiFrac calculates maximum achievable well productivity index (JD) and required fracture geometry.
optiFrac is available online at www.pengtools.com and in AppStore for iPad.
Optimization of Hydraulic Fracturing
In production optimization of hydraulic fracturing, it is important to recognize that for a fixed proppant volume, fracture length and fracture width compete to each other. Consequently, there is an optimum fracture length and width that would maximize the dimensionless productivity index of the fractured well [1].
Typical applications
- Optimization of hydraulic fracturing
- Evaluationg post-fracturing production performance
- Design Sensitivity Studies and Benchmarking
- Optimum fracture design parameters determination:
- 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 CfD and Ix as parameter.
- Plot of JD as a function of CfD and Np as parameter.
- Design optimization curve which corresponds to the maximum JD values for different Np.
- Design Optimum Point at which the dimensionless productivity index, JD, is maximized for the given proppant, fracture and reservoir parameters.
- Physical constraints envelope.
- Proppant library with predefined proppant properties.
- Users Data Worksheet for benchmarking vs actual.
Interface features
- Save and share models with colleagues
- Last saved model on current computer and browser is automatically opened
- Metric and US oilfield units
- Save as image and print plots by means of chart context menu (button at the upper-right corner of chart)
- Download pdf report with input parameters, calculated values and plots
- Select and copy results to Excel or other applications
