... Dipole sonic data is now collected every square mile of active development area. The sonic data is converted into estimates of fracture gradient (psi/ft), minimum horizontal stress (psi), and closure pressure (psi). These fundamental rock mechanic properties are first used to determine...

... porosities, water saturation, total organic carbon, level of organic metamorphism, flow regimes (continuous vs. diffusion-like) at any pressure of interest, as well as Young modulus, Poisson’s ratio and minimum horizontal stress. Based on these estimates, detailed shale and tight reservoirs characteristics...

... by using Stress Polygons and data from diagnostic fracture injection test analysis as a quantification of the minimum horizontal stress. This is of paramount importance since there is not a generic theory about the stress faulting regime for most of the west region of the WCSB. The Eaton method from sonic...

... Abstract Microfrac or fall off injection test is a technique used to accurately measure minimum horizontal stress directly in the formation. However, other than being expensive and time consuming, this test does not give a continuous minimum horizontal stress profile. Continuous minimum...
