Patent number: 9507039Abstract: 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.Type: GrantFiled: December 12, 2011Date of Patent: November 29, 2016Assignee: Schlumberger Technology CorporationInventor: Masahiro Kamata

Publication number: 20150300161Abstract: A system, method and tool for measuring subsurface waves from a wellbore is provided comprising a source for propagating at least earth waves and a drilling tool. The drilling tool may include a drill string comprising a number of drill pipe sections positionable in the wellbore and a bottom hole assembly. The bottom hole assembly may include a sensor package containing a strain gauge to determine strain measurements of the drill string and a subsurface sensor to determine subsurface measurements of earth waves passing through the earth and drill string waves passing through the drill string. Embodiments of the system may compare the strain measurements to the subsurface measurements in order to distinguish drill string waves from earth waves.Type: ApplicationFiled: April 22, 2014Publication date: October 22, 2015Applicant: Schlumberger Technology CorporationInventor: Masahiro Kamata

Patent number: 9036449Abstract: 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.Type: GrantFiled: July 31, 2013Date of Patent: May 19, 2015Assignee: Schlumberger Technology CorporationInventors: Masahiro Kamata, Tsunehisa Kimura
