Microseismic joint location and anisotropic velocity inversion for hydraulic fracturing in a tight Bakken reservoir [PDF]
, 2014 To improve the accuracy of microseismic event locations, we developed a new inversion method with double-difference constraints for determining the hypocenters and the anisotropic velocity model for unconventional reservoirs.

Seismic imaging of hydraulically-stimulated fractures: A numerical study of the effect of the source mechanism [PDF]
, 2012 We present a numerical study of seismic imaging of hydraulically stimulated fractures using a single source from an adjacent fracturing-process. The source is either a point force generated from the perforation of the casing of the well or a double ...

Design of Initial Mining Pressure Relief Scheme for Large‐Size Mining Face: A Case Study
Engineering Reports, Volume 8, Issue 4, April 2026.The numerical simulation analysis method is used to compare the actual mining face (315 m) with the designed mining face (200 m). The results show that the large mining height working face has larger abutment pressure peak and stress concentration factor than the general mining height working face.
