StimPredictor™

New generation fast 3D grid based frac simulator with proppant transport constrained by validated geomechanical half lengths. Resulting fracture geometry used as input in ProdPredictor and commercial reservoir simulators.

Features:

StimPredictor™ is a new generation lightning fast 3D grid based frac simulator with proppant transport. The unique workflow uses the geomechanical half-lengths derived in GMXPredictor™ as a constraint that captures the lateral 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. The rock properties used as input in a frac simulator (Young’s Modulus, Closure stress, etc.) are distributed in 3D using RockPredictor capabilities and extracted with an automatically custom built 3D well grid around the considered well.

• Unique asymmetric 3D grid based 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 or longer wings.
• Automatic match of the pressure in the frac analysis module
• Frac design and analysis are extremely fast yet uses more constraints than any other commercial frac simulator
• Export fracture geometry to commercial reservoir simulators
• Provides the frac geometry to ProdPredictor for prediction of well performance and pressure depletion
