Microseismic Measurement of Fracture Geometry using Synchronized Three Component Geophone Extended Arrays

A North American gas reservoir microseismic test incorporated a 22 node three component geophone array in two monitor wells spaced 1100 meters apart and synchronized with a fiber optic cable connection. In the horizontal treatment well, the geophones were above the interval of interest. A stringshot was performed to orient the geophones and to calibrate a velocity model for the formations through which the microseisms would travel.
