... thermal loading. In this study, we designed a two-layer cement casing structure to evaluate the stress state at the cement-casing interface under high pressure and high temperature conditions. We cured Class-G cement with a water-cement ratio of 0.4 and poured it inside the casing, subjecting it to 40 MPa...

... dominate the overall stress reduction, shifting the stress state towards the failure condition. The flow rate causes a localized effect on the pressure field, due to the high permeability of the reservoir. Heterogeneity in the Young's modulus yields variations in deformation which are of comparable...

Among the current barriers to commercialization of these technologies are a set of risks related to the subsurface state of stress state: the risk of leakage of CO 2 or brine through the sealing formations for GCS...

... ABSTRACT: Identification of in situ stress state is crucial in developing an enhanced geothermal system. Currently, there are no reliable methods to measure in situ stress in geothermal boreholes because conventional borehole technologies (i.e., over-coring, hydraulic fracturing, image log...

... ABSTRACT: To assess the stability of underground openings by using the numerical modeling tool, the stress state (i.e., initial and induced stresses) should be generated accurately. The objective of the present paper is to propose a methodology to numerically initialize the pre-mining stress...
