  • Method for monitoring seismic events
    Patent number: 7647183
    Abstract: A microseismic method of monitoring fracturing operation or other microseismic events in hydrocarbon wells is described using the steps of obtaining multi-component signal recordings from a single monitoring well in the vicinity of a facture or event; and rotating observed signals such that they become independent of at least one component of the moment tensor representing the source mechanism and performing an inversion of the rotated signals to determine the remaining components.
    Type: Grant
    Filed: August 14, 2007
    Date of Patent: January 12, 2010
    Assignee: Schlumberger Technology Corporation
    Inventors: Zuzana Jechumtalova, Leo Eisner
