  • Installation of seismic survey devices in shallow, low-angle boreholes
    Patent number: 7102961
    Abstract: The specification discloses a system and related method for installing seismic sensors in shallow, low-angle boreholes for obtaining conventional three-dimensional and four-dimensional seismic surveys. Installing seismic sensors in shallow, low-angle boreholes removes the sensing devices from surface anomalies that may affect seismic sensing performance. Moreover, installation of the seismic devices in this manner may be done in environmentally sensitive areas without undue environmental impact.
    Type: Grant
    Filed: April 24, 2002
    Date of Patent: September 5, 2006
    Assignee: Halliburton Energy Services, Inc.
