Formation measurements using downhole noise sources

A method of performing measurements of an earth formation includes disposing at least a first receiver and a second receiver in one or more monitoring boreholes in a formation, and injecting fluid into the formation from an injection borehole, wherein injecting includes operating a fluid control device to generate seismic and/or acoustic noise having an identifiable characteristic. The method also includes detecting seismic and/or acoustic signals at the first receiver and detecting seismic and/or acoustic signals at a second receiver, the seismic and/or acoustic signals corresponding to the seismic and/or acoustic noise, calculating an estimate of a green's function between the first receiver and the second receiver by processing seismic and/or acoustic waves detected by the first receiver and the second receiver to at least partially reconstruct the green's function, and estimating variations in a velocity of a region of the formation by determining variations in the reconstructed green's function.. ...

Method for determining formation stress field using microseismic focal mechanisms and applications therefor to predict reservoir formation response before during and after hydraulic fracturing

A method for estimating a fluid pressure required to stimulate a subsurface formation includes using seismic signals detected by a plurality of seismic sensors disposed proximate the subsurface formation. Spatial positions and times of origin (“hypocenters”) of each of a plurality of microseismic events induced by pumping fluid into the subsurface formation are estimated. ... Microseismic Inc

Method for determining maximum horizontal stress magnitude and direction using microseismic derived fracture attributes and its application to evaluating hydraulic fracture stimulation induced stress changes

A method for determining maximum horizontal stress in a subsurface formation includes using recordings of seismic energy detected proximate the subsurface formation to determine hypocenters of microseismic events. A focal mechanism for each microseismic event is determined. ... Microseismic Inc

Multicomponent passive seismic imaging using geometrical optics

A method for passive seismic imaging includes entering into a programmable computer seismic signals measured at a plurality of spaced apart locations above a volume of earth's subsurface to be evaluated. The signals are measured at each location along different directions to enable resolution of motion in three orthogonal directions. ... Microseismic Inc

Method for determining fracture proppant spatial distribution using passive seismic signals

A method for determining spatial distribution of proppant incudes using signals detected by seismic sensors disposed proximate a formation treated by pumping fracturing fluid containing the proppant. Origin time and spatial position of seismic events induced by pumping the fracturing fluid are determined. ... Microseismic Inc

Method of using semblance of corrected amplitudes due to source mechanisms for microseismic event detection and location

A method for determining hypocenters of microseismic events includes entering as input to a computer seismic signals recorded by a plurality of seismic sensors disposed proximate a volume of subsurface to be evaluated. For each point in space in the volume, and for a plurality of preselected origin times, a seismic energy arrival time at each seismic sensor is determined. ... Microseismic Inc
