Hydraulic fracture design, stage by stage.

FastFrac is hydraulic fracture design software for one stage of a frac treatment. Enter well completion, reservoir, rock-mechanics, fluid, proppant and pumping-schedule data. The engine works the job one stage at a time, solving fracture geometry by iterating between the Carter leakoff balance and the elastic width relation.

It returns the frac treatment design in full: rates, volumes, sand, surface pressure and hydraulic horsepower, alongside fracture half length, created width and the propped width each stage places. A geometry view then shows where every stage ends up in the fracture at the end of pumping, and how much of it is still there after leakoff.

Built for multi-stage horizontal and vertical wells in unconventional and conventional reservoirs. Every equation the model applies in hydraulic fracturing, with its published source, is set out on the Basis page inside the software. The design notes work up a complete frac design for one formation at a time, parameter by parameter.

Geometry

Radial growth, or radial growth transitioning to an ellipse at the specified confinement height.

Fluid model

Newtonian treatment fluid characterised by a single viscosity.

Leakoff

Carter balance with per-parcel tracking, so each stage's own losses are resolved.
