Our consultancy service provides computational solutions and independent advice to individual industrial problems. expert users within all aspects of the elfen software suite.
The first commercial ‘all in one’ and advanced application package to answer challenging fracture design problems at multiple scales.
Elfen’s fracture modeling capabilities achieve this within the framework of advanced constitutive laws coupled with fracture initiation, propagation, closure and production algorithms with fluid flow and proppant transport.
Phase II of FracGas JIP starting July 2016 – sponsors still accepted.
Further improve techniques to enable breakthrough, cost effective, fast, safe and profitable solutions
Advanced and tailored fracture designs in complex settings
Assessment of fracture height containment, induced seismicity, arbitrary fracture network evolution, well-well interference, proppant distribution, stimulated rock volume
The new approach lies in the fact that hydraulic fractures can follow arbitrary fracture paths in 2D/3D simulations; as dictated by stress state, material properties and heterogeneity rather than the topology of the finite element mesh. Further to this, only regions near the hydraulic fracture tip are adaptively re-meshed which ensures that stress concentrations can be effectively captured without the need for a computationally expensive global re-mesh.download paper
Elfen tgr technology combines advanced rock constitutive models and continuum damage mechanics with discrete fracturing in arbitrary 3D directions; offering true 3D fracture interaction and propagation capabilities. Models are poro-elasto-plastic, fully coupled with fluid flow within the propagating fractures as well as within the matrix. This allows simulating full cycle of stimulation-production-refracturing-production operations. Stress shadows, hydraulic-natural fracture interactions (DFN stimulation), fracture closure, proppant transport, multi-well interference, formation damage, flow back, mixed mode failure are all accounted for in the analysis to provide a unique and realistic representation of the subsurface hydraulic fracture network growth.view all case studies
