During hydraulic fracturing treatments from horizontal wells, proppant slurries are pumped into the induced fractures to prevent crack closure upon de-pressurization, thus enhancing hydrocarbon recovery. Transport and emplacement of proppant particles may have a strong…
Geomechanica’s guest blog series are written by rock engineering and geomechanics experts. In the second post of these series, we’re showcasing the work of Dr. Murad Abuaisha on “Hydraulic fracturing and induced seismicity by FDEM.” Murad…
The computational engine of Irazu simulation software is based on the finite-discrete element method. This inherently means that Irazu is equipped with a finite element solver (FEM). The FEM solver uses linear elastic constitutive laws…
The multi-facetted experimental and numerical investigation forming the PhD thesis of Geomechanica’s Dr. Bryan Tatone entitled “Investigating the evolution of rock discontinuity asperity degradation and void space morphology under direct shear ” demonstrated the first…
Irazu makes use of state-of-the-art high performance computing techniques to speed-up computations. In particular, we use GPU (graphics processing unit) computing on consumer-grade AMD graphics cards. To demonstrate the improvement in computation speed, five uniaxial…
