Publication number: 20080066822Abstract: A hydrocarbon application hose to avoid substantial compression and blow-out resulting from high pressurization differentials therethrough. The hose is formed from an inner tube that has a layer of material with electromagnetic target, such as carbon fiber, disbursed therethrough. In this manner, the material, generally a polymer, may be electromagnetically heated once the layer has been wrapped with a metallic reinforcing member. Thus, the layer of material may transform into surrounding relation relative to the reinforcing member. A substantially unitary inner tube may thereby be provided that includes a reinforcing member for blowout resistance and is of unitary character for compression resistance.Type: ApplicationFiled: July 31, 2007Publication date: March 20, 2008Inventors: Joseph Varkey, Willem A. Wijnberg, Montie W. Morrison, Sheng Chang

Patent number: 7005583Abstract: An electrical cable includes a first layer, a second layer, and a tie layer, disposed between the first layer and the second layer, for bonding the first layer to the second layer. A method of making an electrical cable includes applying a tie layer to an inner layer, the tie layer being miscible with the inner layer, and bonding an outer layer to the tie layer via one of a chemical reaction therebetween and a physical bond therebetween. An electrical cable includes a first layer, a second layer immiscible with the first layer, and a tie layer disposed between the first layer and the second layer, wherein the tie layer is miscible with the first layer and is capable of bonding with the second layer.Type: GrantFiled: April 25, 2003Date of Patent: February 28, 2006Assignee: Schlumberger Technology CorporationInventors: Joseph P.

Patent number: 6446723Abstract: A description of a cable for connection to sensors permanently downhole is provided, the cable comprising a plurality of elongate conductors capable of operative connection to sensors, a sheath surrounding the elongate conductors and holding the conductors so as to extend substantially parallel to an elongate axis, wherein the sheath has a cross-section, perpendicular to the direction of the elongate axis, which has a major dimension and a minor dimension. The cross-section of the cable is thus flattened and can be in the shape of an ellipse, a crescent or comprise a circle with wing-like portions attached on opposite sides of the circle. The sheath is made from a resilient material, so as to provide a robust outer surface of the cable which ensures the cable can be placed downhole without breaking. A number of the elongate conductors are grouped together and inter-weaved in a helical arrangement, so as to reduce electrical cross-talk between the conductors.Type: GrantFiled: June 9, 1999Date of Patent: September 10, 2002Assignee: Schlumberger Technology CorporationInventors: Rogerio Tadeu Ramos, Willem A. Wijnberg, Christian Jean Marcel Chouzenoux, Stephanie Marie-Odile Montillet

Patent number: 6441618Abstract: Sensors are permanently placed in the ground near observation and injection wells in order to passively and continuously monitor the status of seawater advance toward fresh water aquifers near coastal cities as well as the status of fresh water injected into the injection wells. Such sensor devices are installed in the ground and electrically connected to surface acquisition equipment that would, without human intervention, transmit acquired data to a centralized facility for processing and interpretation. Various types of sensors can be used: the sensors used for general reservoir monitoring and/or the sensors used for leak detection, soil heating, and temperature mapping. Alternatively, a special type of sensor can be designed and provided for the purpose of monitoring the status of seawater advance toward fresh water aquifers.Type: GrantFiled: January 29, 2001Date of Patent: August 27, 2002Assignee: Schlumberger Technology CorporationInventors: David J. Rossi, Willem A. Wijnberg, Peter V. Howard, Jean-Pierre R. Delhomme, Kamal Babour
