Local stress accumulation in reservoirs could cause sudden failure and therefore a micro-earthquake or induced earthquakes.Numerous mechanisms generate microseismicity,and these may include gas storage,hydraulic fracturing,fluid injection,production-related reservoir compaction,presence of low-porosity reservoirs,high injection pressures,the use of fluids the local stressproppants,the stress results for this questionHow are local stresses determined?How are local stresses determined?The local stresses are then determined by superposition of the numerical and analytical solutions.The local stress increase around an isolated new cavity may create other neighboring organized cavities to form a craze precursor.Local Stress - an overview ScienceDirect Topics results for this questionWhat is local strain approach?What is local strain approach?In other words The local strain approach relates deformation occurring in the immediate vicinity of a stress concentration to the remote or local pseudo-elastic stresses and strains using the constitutive response determined from fatigue tests on simple laboratory specimens (i.e.the cyclic stress-strain curve and the strain-life curve.The Local Stress-Strain Fatigue Method
