... from one of the rare existing drilling cores. Rock density ranges from 2.1-2.8 g/cm 3 indicating different lithologies with porosity ranging from 0.3-19.1 %. Mechanical behavior of the aquifer was investigated by dynamic and static methods. Young's Modulus ranges from 3-103 GPa and rock strength from...

... Young's modulus ( E ) and Poisson's ratio (υ), determined for post-salt carbonate reservoir samples recovered from an oil field in the Campos basin, Brazilian offshore. The samples lithofacies was described as peloidal packstone with bioclasts and microoncoliths. The elastic properties were calculated...

... the stresses in the rock mass and that small deformations along an existing shear zone can cause significant instabilities in the surrounding rock mass resulting in an increase in the size of the cavity. Supporting of the rock mass and backfilling of the cavity with materials having a Young's modulus of larger...

... opening is perpendicular to these planes. The dynamic Young's modulus is larger than the static one (up to 2.2 times) before loading. For the perpendicular loading direction, the ratio of dynamic to static moduli decreases continuously, suggesting an increase in hydraulic connectivity of the pore space...

The discontinuities showed to be a mirrored function of the Young's modulus, with an inverse proportion to that when considered the spacing of discontinuities. 1 Introduction ISRM Suggested Methods on Borehole Geophysics for Rock Engineering describes a series of borehole geophysical...

... experiments were performed on these rocks in order to estimate and compare the Young’s Modulus, the Poisson’s ratio and the Bulk Modulus obtained by static and dynamic methods. Our results shows that the elastic moduli obtained by the static and dynamic experiments are in the same order of magnitude. 1...
