New Inversion Method to Determine In-Situ Stress From Borehole Induced Fractures

International Petroleum Technology Conference, 2014
Abstract The drilling induced tensile fractures can be observed from borehole image logs but they must be differentiated from natural fractures. This paper focuses on the understanding of hydraulically or artificially induced tensile fractures while drilling.

The in-situ stress prediction of a fractured shale reservoir based on AVAZ inversion: A case study from Southwest China

Geophysics
In-situ stress estimation of a shale reservoir is critical for the design of shale hydraulic fracturing and well-bore stability analysis. Fractured shales have orthogonal anisotropy (OA) because of the presence of vertical fractures and lamination ...

HTI ANISOTROPY PARAMETERS INVERSION VIA AZIMUTHAL SEISMIC VELOCITY ANISOTROPY AND ITS APPLICATION TO ANISOTROPIC 3D IN-SITU STRESS ESTIMATION

Geophysics
The anisotropic parameters inversion in horizontal transverse isotropy (HTI) medium plays an important role in predicting the fracture density as well as the anisotropic in-situ stress for unconventional reservoirs.

In-situ stress field inversion for pumped storage underground caverns: comparing GA-BP neural network and multivariate regression

International Conference on Advances in Energy and Environmental Engineering (AEEE 2026)
For the purpose of evaluating stability and designing subsurface caverns in pumped-storage projects, precise reconstruction of the initial in-situ stress field is essential.
