... plots such as Volume to First Response (VFR), Instantaneous Shut-in Pressure (ISIP), Rate Transient Analysis (RTA) and by characterizing the number of fractures using fracture-type diagnostics. Shear fractures maximize the fracture surface area (FSA) of the well; tensile fractures have limited FSA...

.... Fracture closure plays an important role and the initial SRV may be very different from the effective SRV. This study demonstrates a unique physics-based simulation driven methodology of dynamically generating an SRV that represents the complex nature of its geometry, in which both tensile fractures...

... not been extensively studied in laboratory tests under relevant conditions. In this work, a cylindrical Eagle Ford shale sample having a single fracture (tensile fracture) was used to perform laboratory injection test with concurrent acoustic emission (AE) monitoring. In the test, slip was induced...

... fracture that activate pre-existing fractures. Various characteristics are discussed of these two extreme conceptual models, particularly differences in injection pressure and microseismic moment release. The model containing the aseismic, tensile fracture represents the lowest energy state and is most...

..., a zone of low fracture initiation pressure and high stress anisotropy was identified at Well A. This zone correlates with an interval where a high concentration of drilling-induced tensile fractures is observed on an FMI image log. While the zone of low fracture initiation pressure is observed to extend...

... the solution limitations by combining fracturing and image log data for determining the complete stress field using data from a single wellbore. Fracturing data (e.g., leak-off tests) and image log information (i.e., tensile fracture characteristics) are utilized to determine the in-situ stress field using...

... of the microseismic and hydraulic fracturing data. Despite the limited amount of well log data available, we estimate the current stress state to be characterized by a NF/SS regime, with Pp = 0.66 psi/ft, Sv =1.05 psi/ft, Shmin =0.79–0.85 psi/ft. Published data of drilling-induced tensile fractures observed...
