Geomechanics of fracture caging in wellbores

Iterative coupling of flow, geomechanics and adaptive phase-field fracture including level-set crack width approaches

In this work, we present numerical studies of fixed-stress iterative coupling for solving flow and geomechanics with propagating fractures in a porous medium. Specifically, fracture propagations are described by employing a phasefield approach. The extension to fixed-stress splitting to propagating phase-field fractures and systematic investigation of its properties are important enhancements t...

MODELLING CaC03 DEPOSITION IN GEOTHERMAL WELLBORES

The capacity of a geothermal liquid to carry calcium varies mainly with the concentrations of CO, and HCO,, temperature and ionic strength, of which the CO, concentration (pressure) changes most in the wellbore. Wellbore models that carry accurate computations for CO, and other gas pressures might be adapted to compute profile thicknesses of CaCO, scale. A general model for carbonate scale depo...
