...-for-purpose solutions for all SAGD projects in Alberta. Steel teeth roller cone bits require extensive extra-thick layers of hard-facing to resist tooth wear. Sand washing through the cones causes high levels of erosion which is hindered by extensive hard-facing. The gauge areas of the bits are rotated...

... from time tm to tm+1. Based on Equation 1, in order to find erosion rate (Er = W/M) on the surface, we need to know the velocity V and impact angle of the attacking particles as well as the type of both erosive and eroded materials Because the erosional characteristics of materials are known...

... and an erosion process by which sand grains are detached from the solid matrix due to both fluid and stress gradients. More precisely, the plastic shear deformation of a sand matrix around a well during drilling and pressure drawdown increases the erosion potential. In return, the erosion process also weakens...

... geomechanics model to a two-phase reservoir flow model. A sand erosion model is postulated after the onset of sand production, which is determined based on the degree of plastic deformation inside the reservoir formation calculated by the coupled reservoir-geomechanics model. Both the enhanced production...

... of an experiment that involves sand production and wormhole propagation in a sand pack as fluid is drawn from it through a small orifice. The computations are based on a recently developed sand erosion model that describes the disaggregation of sand particles as a function of sand matrix strength and fluid flux...

... is formulated in a consistent manner within the framework of mixture theory with the porosity as one of the main field state variables. The latter is split into two parts: one related to volume changes as a result of erosion in the oil sand matrix, and the other one due to deformations in the matrix subjected...
