... Abstract A model of induced seismicity caused by water injection is considered. Analysis is based on the assumption of the existence of listric (curvilinear) faults. This presumes that shear stresses acting on the fault may be close to shear resistance at a certain part of the fault surface...

... Abstract Geologic, and historical well failure, production, and injection data were analyzed to guide development of three-dimensional geomechanical models of the Belridge Diatomite Field, California. The central premise of the numerical simulations is that spatial gradients in pore pressure...

... Abstract Steam injection through a vertical or horizontal well has been commonly exercised in heavy-oil reservoirs to enhance oil recovery. Thermally-induced effects may enhance the mobility of the formation by increasing the reservoir permeability and reducing the oil viscosity, but it can...

... Abstract Water-injection is often implemented in oil reservoirs with mainly two goals. On one hand, it provides an efficient means of secondary production in water-wet fields by sweepage and pressure maintenance. On the other hand and precisely because of pressure maintenance it generally...

The results of the modelling could be used as basis for explaining the observed behaviour of the Ekofisk field, provide possible guidelines to future actions in the development of the Ekofisk field, and as input to large-scale models of the Ekofisk field. effective vertical stress...

... Abstract Massive injection of slurried solid waste generates permanent strains and displacements. These can be measured and analyzed to give useful information related to the shape and orientation of the injected body, and therefore lead to a monitoring approach based on accurate surface...

.... No change in injectivity was noticed and so the fine filters on all Forties platforms were by-passed. No deleterious effects have been noticed during the four years of injection without fine filters on Forties. The conclusion from the Forties study is that fine filtering seawater is often unnecessary...
