Abstract: Methods and systems for acoustically determining reservoir parameters of subterranean formations. A tool comprising at least one seismic source or seismic receiver mounted thereon; a conveyance configured for movement of the acoustic tool in a borehole traversing the subterranean formations; and a source retainer configured or designed for permanent deployment in the borehole to removably retain the acoustic tool in the borehole. The source retainer when deployed provides acoustic coupling with the borehole and removably retains the acoustic tool in the borehole so that, over multiple deployments, the acoustic tool is repeatedly deployed at the same predetermined location and orientation relative to the subterranean formation, and with the same acoustic coupling to the borehole.

Abstract: Methods and systems utilizing seismic sensors configured or designed for use in seismic signal detection are provided so as to reduce the occurrence of spurious responses of the sensors. A method of seismic surveying using a seismic sensor may include the steps of deploying the seismic sensor at a location for seismic signal detection and acquiring seismic signals. The seismic signals may include high frequency response signals containing spurious response signals at an identifiable bandwith. The method may further include applying spurious response cancellation based on the bandwidth location of the spurious response signals and generating modified seismic waveforms having extended frequency bandwidth.

Abstract: A seismic source of the present disclosure includes a first rotation member and a second rotation member having a common axis of rotation and rotated at a same rotational rate in mutually opposite directions. In addition, the seismic source may include a first mass that is eccentrically coupled to the first rotation member and rotates along with the first rotation member. A second mass may be eccentrically coupled to the second rotation member and configured to rotate along with that member. The second mass may be configured such that the center of gravity of the second mass is located radially external to the center of gravity of the first mass relative to the common axis of rotation. The center of gravities of the first and second mass may be located at the same location along a length of the common axis of rotation.
