... of parameters from the blast design scenarios at the mine site were simulated and optimized designs were proposed based on the MBF and MSW modelling. The MBF model explicitly simulates all blast design parameters. The MSW blast vibration model uses multiple seed waveforms at different distances from a blasthole...

.... INTRODUCTION Pulling a 20-inch surface casing from cemented borehole encounters challenges. In a field scenario, the evaluated pulling force can be more than 1000 tons to trip out a 10-meter surface casing. The downhole pulling tool limits the pulling force up to 350 tons in many situations. This allows only...

... show that the two-well configuration performs better in energy performance and environmental performance, but worse in economic performance. Additionally, for the three-well configuration, the scenario with two injection wells performs better than that with only one injection well with respect...

...), but their anisotropic elasticity is normally neglected, either because of model limitations, or in lack of input data. Here, however, the impact of anisotropy along with the elastic contrast between undrained surroundings and drained (isotropic) reservoir rock is addressed through a series of numerical scenarios...

... failure envelope parameters estimated through triaxial laboratory experiments to model the total stress increases at failure for a wide range of loading scenarios and medium orientations. We consider both isotropic and anisotropic pore pressure parameters - we explore the differences in modelling outcomes...

... compressive stress was observed with the help of Distinct-element modeling (DEM) using 3DEC software. The pillar’s rock mass is simulated using Elastic and Mohr-Coulomb constitutive models. Two scenarios are presented to assess the pillar strength with and without the presence of karst. Pillar strength...

... into the model and survey six fault scenarios with various fault-zone structures and fault upper extents. We compare the modeled Coulomb stress changes against earthquake triggering thresholds obtained from a detailed in-situ stress model, and identify implausible and plausible scenarios. The plausible scenarios...

... simulation models. Some parameters such as type of proppant, fracture fluids, number of stages, fracture length, and fracture width are evaluated considering the reservoir’s high temperature and high pressure. Finally, different scenarios are evaluated to know if the hydraulic model is economically feasible...

.... The results presented herein address performance and accuracy issues, stress parameter setup in fracture propagation and thermal front evolution models. It was found that working with multiple meshes in numerical simulation runs is advantageous because it enables dealing with more complex scenarios while...

It was found that with a constant in-situ stress and different annulus pressures (before cementing), the cemented annulus behaved in different manner. The worst scenario could lead the cement-rock interface open and the wellbore lost the integrity. 1...
