A fully integrated hydraulic fracturing and reservoir simulator

The full well life cycle in one seamless simulation. 

Full coupling between hydraulic fracturing, the wellbore, and the reservoir.

Constitutive laws seamlessly transition between mechanically open and mechanically closed fractures, with and without proppant.

We provide a detailed technical writeup.

Industry-leading realism in fluid flow and proppant transport

 

Fracture fluid flow includes multiphase, non-Darcy, and non-Newtonian flow effects.

Proppant transport includes bulk gravitational convection, gravitational settling, hindered settling, clustered settling, screenout, and the effect of proppant on slurry viscosity.

Non-Newtonian fluid rheology using the modified power law.

Rigorously simulate long-term production

 

​Model fracturing treatment, post-injection closure, and long-term production in a single continuous simulation.

Evaluate designs based on production, rather than unreliable proxies such as stimulated reservoir volume and effective fracture length.

Production simulation fully incorporates pressure drop along the fracture during production from processes such as multiphase flow and non-Darcy effects.

Both black oil and compositional fluid models are fully supported: realistically describe any fluid system, such as black oil, retrograde condensate, or dry gas.

True three-dimensional simulation

Fully capture 3D effects in fracture propagation, proppant placement, multiphase flow, and other physics. 

In the movie below, the well is completed in a high stress zone. The fracture propagates upward into an oil-saturated low-stress zone. The fracture propagates further upward into an overlying water-saturated intermediate-stress zone. Proppant is carried upward and placed in the low-stress zone. During production, the oil goes below the bubble point, forming gas.  Buoyancy causes the gas to rise upward into the overlying water saturated zone, creating a complex three-phase flow pattern.

Poroelastic stress effects from depletion

Pressure changes during production change the stress, impacting fracturing of child wells, refracturing, and changes in frac conductivity during primary depletion.
