The new experiment method of stress sensitivity evaluation in the low permeability oil-gas reservoirs;

Evaluation on stress sensitivity of the low-permeability fractured reservoirs;

Lab research on stress sensitivity of low permeability gas reservoirs;

The recent progress in protective methods,techniques,and technologies and in drilling/completion fluids for fractured oil and gas reservoirs is reviewed in topics including fractured reservoir classification,reservoir stress sensibility evaluation,fracture wideness estimation,formation damaging and temporarily plugging mechanisms,and drilling/completion fluids.

Porosity is stronger effected by porosity stress sensibility.

Therefore, it has important significance to study the porosity and permeability stress sensibility.

Influence of Different Ageing Process on Stress Corrosion Cracking Sensitivity of 2519 Aluminum Alloy Hot Rolled Plate;

Influence of heat treatment on mechanical properties and stress corrosion sensitivity of 2519 aluminum alloy plate;

The purpose of the research is to compare the effect of different alloying constituents on the stress corrosion sensitivity.

The subject of investigations included SCC susceptibility of API X-60 pipeline steel at various testing conditions in the soil containing water, hydrogen concentration in the steel an the role of hydrogen in cracking process.
