Software

FracPredictor™ brings to the E&P industry a quantum leap in technologies that achieves the true integration of Geophysics, Geology and Geomechanics (3G) to solve GeoEngineering problems commonly found in shale and tight reservoirs. The 3G software includes multiple modules that address the needs of geophysicists, geologists and engineers.


DrillPredictor™

DrillPredictor™ includes a new technology that uses standard surface drilling data to compute, in real time, the Corrected Mechanical Specific Energy (CMSE) which accounts for frictional losses along the wellbore. FracGeo’s CMSE is used to compute pore pressure, stresses, natural fractures, and geomechanical logs along the wellbore. These logs are then used in FracGeo’s GMXsteering™ technology to update 3D geomechanical models in real time to steer the well into the most fracable rock. Immediately after drilling is completed, DrillPredictor™ provides an optimal completion strategy with adaptive frac stage spacing and cluster design that accounts for the heterogeneous nature of the computed stress and geomechanical properties along the wellbore.


Features
• Cloud based web application that enables FracGeo’s GMXsteering™ technology available on any drilling rig through the use of FracGeo’s partner, RigMinder© data streaming services.
• Corrected Mechanical Specific Energy (CMSE) that accounts for frictional losses in real time.
• Estimates in real time, or after drilling is completed, the pore pressure, geomechanical logs, natural fracture index and the stress brittleness.
• Provides at the end of drilling the optimal frac stage spacing and cluster density based on stress brittleness, Shmin, or CMSE.
• Exports the derived completion design to StimPredictor™ to design the frac treatment.

LogPredictor™

LogPredictor™ displays, for Quality Control (QC) and interpretation, log data in a user friendly log window.

RockPredictor™ uses a 3D geocellular grid, seismic attributes and well data to propagate in 3-Dimensions, key rock properties such as facies, TOC, brittleness, porosity and natural fracture density.

GMXPredictor™

A new Geomechanical technology based on the Material Point Method (MPM), is able to simulate 1) the initial heterogeneous reservoir stress magnitude and orientation resulting from the interaction between regional stress and natural fractures, and 2) the interaction between hydraulic fractures and natural fractures during stimulation. This unique technology opens new doors to derive a better understanding of the frac stage performance. This provides the ability to create completion optimization workflows. Unlike other geomechanical tools, GMXPredictor’s simulated strain predicts the main features of the microseismicity--confirming the validity of the input data (continuous natural fracture models) and the continuum mechanics approach used to simulate the interaction between the hydraulic and natural fractures responsible for the shearing observed in the microseismicity.


Features
• Provides the horizontal differential stress that could be used to identify areas where the fracing treatment needs to be changed or stages to be refraced.
• Provides local stress rotations and the direction of propagation of a hydraulic fracture at each stage.
• Simulates the hydraulic fracturing process and provides the strain which is a good proxy for the stimulated reservoir volume, or microseismicity. The strain is used to estimate the geomechanical half lengths which are used as constraints in frac design.
• Accounts for pressure depletion using poroelaticity to model frac hits.

StimPredictor™

An asymmetric analytical frac design was developed and implemented in StimPredictor™. The unique workflow uses the geomechanical half-lengths derived in GMXPredictor™ as a constraint that captures the stress gradients that control the asymmetric hydraulic fracture propagation. Experimental design and sensitivity analysis provide tornado plots which explain why certain frac stages do or do not perform well, allowing the frac engineer to identify what frac parameter(s) they need to change to adapt the frac stage treatment to the stress gradients reducing hydraulic fracture growth.


Features
• Unique asymmetric analytical frac design constrained by geomechanical half lengths that captures stress gradients causing the asymmetric behavior.
• Experimental design for sensitivity analysis allows the identification of frac parameters causing shorter wings.
• Proppant distribution with and without gravity settling effects.
• Export to reservoir simulators and other frac design software

The module uses an asymmetric tri-linear model that provides a mechanistic model to represent the production from the unconventional wells. The new tri-linear model is as fast as a simplistic Decline Curve Analysis, yet it provides a reliable and realistic estimate of the EUR which honors the complex asymmetric nature of the SRV in unconventional wells.
