Abstract: A remotely actuated clamping device for a borehole seismic sensing system. The remotely actuated clamping device includes a clamping mechanism configured to engage a surface of a borehole by actuation of the clamping mechanism. The remotely actuated clamping device also includes a fluid based actuator configured to actuate the clamping mechanism. The fluid based actuator includes a chamber configured to be kept at a pressure that is isolated from an ambient pressure of the borehole. The fluid based actuator also includes a piston within the chamber. The chamber receives a pressurized fluid to move the piston within the chamber to actuate the clamping mechanism. The pressure used to actuate the clamping mechanism is independent of the ambient pressure of the borehole. Also disclosed are methods of operating the device.
