We applied the empirical Green's function have been developed to determine the precise hypocenter method to retrieve the relative source time functions (RSTF) locations for a cluster of 157 microearthquakes induced by of larger microearthquakes and estimate the source parameters hydraulic fracturing at Los Alamos Hot Dry Rock (HDR) of the induced seismic events.

Full-waveform acoustic logging has advanced significantly in both theory and application in recent years, and these advances have greatly increased the capability of log analysts to measure the physical properties of formations. Advances in theory provide the analytical tools required to understand the properties of measured seismic waves. The theory demonstrates that all parts of recorded waveforms are influenced by waveguide properties, even in the case of dipole- and quadrupole-source logging. The theory also indicates that these waveguide mode properties can be used to design velocity and attenuation picking schemes and shows how source frequency spectra can be selected to optimize results in specific applications. Synthetic microseismograms are an effective tool in waveform-interpretation theory; they demonstrate how shear-arrival picks and mode-attenuation measurements can be used to compute shear velocity, intrinsic attenuation, and formation permeability for monopole, dipole, and quadrupole sources. Array processing of multi-receiver data offers the opportunity to apply even more-sophisticated analysis techniques. Synthetic microseismograms are used to illustrate the application of maximum-likelihood method, semblance cross-correlation, and Prony's method. The interpretation of acoustic-waveform logs is illustrated by reviews of various practical applications, including synthetic seismogram generation, lithology determination, estimation of geomechanical properties in situ, permeability estimation, and design of hydraulic-fracture operations.
