Patent number: 6768700Abstract: A downhole string includes a system having an actuator module that is responsive to electrical power and signals communicated down a cable, such as a permanent downhole cable (PDC). In addition, a backup mechanism, such as an inductive coupler mechanism or another type of wireless apparatus, can be used as a backup to restore power and communications with the downhole system. For example, if the cable fails for some reason, power and signals can still be communicated with the inductive coupler mechanism or other wireless mechanism to control operation of the system or to receive signals from the system.Type: GrantFiled: February 22, 2001Date of Patent: July 27, 2004Assignee: Schlumberger Technology CorporationInventors: Anthony F.

Patent number: 6386296Abstract: A method and apparatus to protect explosive components used in various tools, such as tools for use in wellbores, includes a component with an adsorptive material. Example tools include perforating gun strings that include shaped charges, detonating cords, and booster explosives. Other tools may include surface tools containing explosive components. In these tools, a build up of corrosive gases or liquids may occur, which may cause damage to the explosive components. As a result, the structural integrity or reliability and thermal stability may be weakened or reduced. To reduce the amount of build up of corrosive gases or liquids, an adsorptive material is placed inside tools in the proximity of explosive components.Type: GrantFiled: June 19, 2000Date of Patent: May 14, 2002Assignee: Schlumberger Technology CorporationInventors: Manish Kothari, Wenbo Yang, Alfredo Fayard, Anthony F.

Publication number: 20010037883Abstract: An apparatus for use in a subterranean well includes a valve, a transducer and a circuit. The valve is adapted to propagate acoustic energy in response to a well fluid flow contacting the valve. The transducer is acoustically coupled to the valve and isolated from the flow to furnish an indication of the acoustic energy. The circuit is adapted to furnish signals to transmit stimuli indicative of the characteristic to a surface of the well based on the indication furnished by the transducer.Type: ApplicationFiled: November 18, 1998Publication date: November 8, 2001Inventors: ANTHONY F.

An indication is received of the state at a surface of the well, and the model is modified based on the indication. The system includes a communication link, a circuit and a machine. The communication link is adapted to furnish an indication of a state of the equipment to the surface of the well. The circuit is located downhole and is adapted to detect the state and produce the indication. The machine is adapted to provide a model describing behavior of the equipment and modify the model based on the indication.Type: GrantFiled: November 18, 1998Date of Patent: October 30, 2001Assignee: Schlumberger Technology Corp.Inventors: Guy Vachon Laborde, Anthony F.

Patent number: 6138754Abstract: A system for use in a subterranean well includes a production tubing and a valve. The production tubing has a port to receive well fluid from a formation. The valve is mounted to the production tubing and includes a sealed housing, a motor, a valve cover, an actuator drive and a sensor. The motor is located inside the housing, and the actuator drive is actuated by the motor to move the valve cover over the port to selectively control the communication of the well fluid between the formation and the passageway of the tubing. The sealed housing may permit the well fluid to accumulate inside the housing over time. The sensor is located inside the housing and provides an indication of the amount of well fluid that has accumulated inside the housing. This information may be useful for such exemplary purposes as predicting when the valve will fail and for evaluating the condition of the valve.Type: GrantFiled: November 18, 1998Date of Patent: October 31, 2000Assignee: Schlumberger Technology CorporationInventors: Anthony F. Veneruso, Gerald W. Robertson

Patent number: 5521592Abstract: A method and apparatus for transmitting information relating to the operation of an electrical device disposed in a borehole, in which information picked up by at least one downhole sensor is conveyed to surface reception means via the wire connection connecting said device to electrical power supply means on the surface, the invention being characterized in that said wire connection is inductively coupled firstly with said sensor and secondly with said reception means.Type: GrantFiled: July 20, 1994Date of Patent: May 28, 1996Assignee: Schlumberger Technology CorporationInventor: Anthony F. Veneruso

Patent number: 5174161Abstract: A method for more accurately measuring small changes in flowrate, and measuring low flowrates, of a well fluid in a pipe, adapted to be disposed in a borehole, includes inserting a choke in a constricted section of the pipe and placing a differential pressure gauge across the constricted section so as to measure the pressure of the fluid in the constricted section. The presence of the centerbody in the constricted section of the pipe decreases the pressure of the fluid in an annulus region around the choke and converts an otherwise small well fluid pressure change in the constricted section into a large pressure change in the annulus region, the large pressure change being easily measurable by the differential pressure gauge.Type: GrantFiled: April 27, 1990Date of Patent: December 29, 1992Assignee: Schlumberger Technology CorporationInventors: Anthony F. Veneruso, Andrew Hunt
