Paper Number: SPE-78155-MS
... Abstract An accurate knowledge of porosity and permeability is crucial to accurate simulation of reservoir performance and enhanced reservoir management. Porosity and single-phase permeability of reservoir rocks is dependent on the stress experienced by the rock mass, which in the simplest case...

... Abstract The temperature effects of high power lasers on rock strength and mechanical properties are presented. It was found that the high temperature induced by lasers drilling through rock enhances porosity and permeability and reduces strength. High temperature causes microcracks, vaporizes...

... at any given porosity. For reservoirs in which the vertical stress is larger than the two horizontal stresses, there is also a potential to induce normal faulting in a depleting reservoir when the change of minimum horizontal stress, ΔS h , exceeds a critical fraction of ΔP p (the change in formation...
