... 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...

The coupled simulations show that plasticity significantly increases the compressibility of the rocks and the compaction drive energy of the reservoir. The initial stress state of the reservoir...

... permeability changes observed in laboratory experiments conducted on siliciclastic and carbonate petroleum-reservoir rocks. We find that the shape of the yield surface has significant impact on post-yield fluid flow response. Differences in behavior between the rock types tested can be explained qualitatively...

... Abstract Qualitative determination of formation permeability is often obtained through laboratory flow tests on core plugs. However, the experimental determination of the permeability for anisotropic plugs (particularly the horizontal permeability) is difficult and less than perfect; generally...

... Abstract Allowing sand to be produced together with the oil is a field proven technique to economically produce heavy oil reservoirs. By doing this, the performance of the wells is increased owing to a number of factors including an increased near wellbore permeability and/or the development...

Interpreted this way, the results of laboratory sand production experiments are used to derive an empirical relationship between loading factor, Reynold's number and the rate of sand...

... 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...

A case study for inclined wellbore problems was also conducted. The effects of single- and dual-porosity, time, and mud weight...

... Abstract We have performed a series of coupled deformation and permeability experiments on "synthetic" fault gouge to investigate the influence of "shaliness" on fluid flow properties. Biminerallic gouge layers were sheared between steel sliders under triaxial compression and permeability...
