Patent number: 7602668Abstract: Sensors located in the vicinity of a hydrocarbon-producing well receive power and communicate with one or more hubs located in the well or at the outer surface of a casing by means of elastodynamic waves. Each hub incorporates a plurality of transducers which permit focusing of the emitted elastodynamic waves. In order to concentrate the energy on a single sensor, or a group of sensors arranged in a cluster. Hubs and sensors communicate by exchanging, modulated elastodynamic waves. Sensors belonging to a cluster may transmit, properly time-shifted elastodynamic waves, in order to collectively focus their energy in the direction of a hub. Time synchronization between the sensors within a cluster may be accomplished by means of electromagnetic fields which travel much faster than elastodynamic waves, but can only propagate over short distances in typical formations.Type: GrantFiled: November 3, 2006Date of Patent: October 13, 2009Assignee: Schlumberger Technology CorporationInventors: Kenneth Kin-nam Liang, Jacques Jundt, Philippe Salamitou

An interpretation element further is utilized to provide a parameter of the fluid moving through the fluid channel based upon data from the vibrating wire following actuation by the actuation element.Type: GrantFiled: November 8, 2007Date of Patent: August 18, 2009Assignee: Schlumberger Technology CorporationInventors: Christopher Harrison, Isabelle Etchart, Kai Hsu, Jacques Jundt, Anthony Robert Holmes Goodwin, Sophie Godefroy, Matthew Sullivan, Antoine Fornari
