See What Users Have To Say

“We have been successfully using XSite for over 12 years for hydraulic fracturing modeling in both conventional and unconventional reservoirs. We really like that this code accounts for much of the physics involved in the hydraulic fracturing process. Our projects have greatly benefited not only from XSite’s advanced capabilities but also from the close interaction and collaboration that ITASCA has offered us since the beginning of our relationship.”

  • Fluid flow and mechanical simulations can be done separately or coupled

  • The fluid flow is approximated by a flow through a network of pipes that connect fluid elements, located at the centers of either broken springs or springs intersected by pre-existing joints

  • The flow pipe network is dynamic and automatically updated by connecting newly formed micro-cracks to the existing flow network

  • Non-steady fluid flow is modeled within the joint network and intact rock, maintaining continuity of fluid mass and pressures between joints and the rock matrix

  • Effective stress calculations are carried out

  • Fracture permeability depends on aperture, or on the deformation of the solid model

  • Fluid pressure affects both deformation and the strength of the solid model

  • The deformation of the solid model affects the fluid pressures (i.e., fluid pressure changes under undrained conditions)

  • Includes logic for simulation of proppant transport and placement

  • Newtonian and power-law fluid flow available

  • Non-Darcy effects and pressure drop at perforation clusters are possible

  • Represents leakoff explicitly, as flow into DFN and porous medium flow into rock matrix, or as Carter leakoff

  • Synthetic microseismic events are formed in the model by new micro-crack (tensile bond breaks) and slip on existing joints (assuming all slips are seismic)

  • Since springs are brittle and their breakage always results in local instability, it is possible to estimate radiated seismic energy based on transient change in strain energy in the vicinity of the broken spring or micro-crack

  • In the case of slippage across natural fractures, the energy released by the slip events is calculated based on the slip area, slip magnitude, and elastic properties of the surrounding medium

  • Events that are related spatially and temporally are clustered together
