20110083771 | OVERFLOW PREVENTION APPARATUS FOR USE WITH FUEL TANKS - Overflow prevention apparatus for use with fuel tanks are described herein. An example overflow prevention apparatus includes a fluid coupling configured to fluidly couple a fluid tank to a liquid fill passage. The fluid coupling includes a first portion configured to receive a liquid via the liquid fill passage and a second elongate portion configured to convey the liquid received via the liquid fill passage to the fluid tank. The second elongate portion has an aperture adjacent an end of the second portion. Also, the second portion is configured to extend into the fluid tank to prevent at least one of a gas or vapor from flowing between the fluid tank and the liquid fill passage when a liquid in the fluid tank is in the aperture. | 04-14-2011 |
20110083772 | APPARATUS AND METHODS TO COUPLE FUEL DELIVERY SYSTEM COMPONENTS TO FUEL TANKS - Apparatus and methods to couple fuel delivery system components to fuel tanks are described herein. An example liquid containment apparatus includes a fuel tank having a cavity to store a liquid fuel. The fuel tank includes only one opening in fluid communication with the cavity. A coupling apparatus is coupled to a portion of the fuel tank to provide a passage between an exterior surface of the fuel tank and the cavity. The coupling receives a plurality of components of a fuel delivery system. | 04-14-2011 |
20110083989 | APPARATUS AND METHODS FOR PERMANENTLY ATTACHING FUEL DELIVERY SYSTEM COMPONENTS TO FUEL TANKS - Apparatus and methods to permanently attach fuel delivery system components to fuel tanks are described herein. An example apparatus includes an insert material integrally formed with at least a portion of the fuel tank. The insert material includes a first layer material having a low permeation characteristic and a second layer material adjacent the first layer material having a relatively lower melting point than a melting point of the first layer material to enable permanent attachment of a coupling apparatus to a surface of the fuel tank by melting at least a portion of the second layer material. | 04-14-2011 |
20110084073 | APPARATUS AND METHODS FOR MOUNTING FUEL DELIVERY SYSTEM COMPONENTS TO FUEL TANKS - Apparatus and methods for mounting fuel delivery system components to fuel tanks are described herein. An example fuel tank includes a housing having a cavity to store a liquid fuel and a boss integrally formed with and protruding from a surface of the housing to receive a fuel delivery system component. The boss receives a threaded fastener to couple the fuel delivery system component to the surface of the fuel tank. | 04-14-2011 |
20110084076 | PRESSURE RELIEF APPARATUS FOR USE WITH FUEL DELIVERY SYSTEMS - Pressure relief apparatus for use with fuel delivery systems are described herein. An example pressure relief apparatus includes a pressure relief system coupled to a body of a fuel cap to define a first side of the body and a second side of the body. The pressure relief system comprises a plurality of fluid valves to enable fluid flow from the first side of the body to the second side of the body when a first pressure differential across the pressure relief system from the first side to the second side is greater than a first reference pressure and to enable fluid flow from the second side of the body to the first side of the body when a second pressure differential across the pressure relief system from the second side to the first side is greater than a second reference pressure. | 04-14-2011 |

20080210441 | Method and Apparatus for Connecting, Installing, and Retrieving a Coiled Tubing-Conveyed Electrical Submersible Pump - A wellhead system has a wellhead of a subterranean hydrocarbon well, a coiled tubing hanger in the wellhead, a coiled tubing hanger extension connected to a top portion of the coiled tubing hanger, a first seal inside the coiled tubing hanger extension, the first seal and the coiled tubing hanger extension defining a sealed space in the coiled tubing hanger extension. Coiled tubing extends into the sealed space in the coiled tubing hanger extension and being suspended by the coiled tubing hanger and the coiled tubing hanger extension, the coiled tubing extending into the wellhead. A downhole electrical cable extends through the coiled tubing and into the sealed space in the coiled tubing hanger extension. An electrical connector extends through the seal and is connected electrically to the cable. The electrical connector has an electrical circuit having an electrically open and an electrically closed position. | 09-04-2008 |
20090211755 | SYSTEM AND METHOD FOR INJECTION INTO A WELL ZONE - A technique facilitates a water flood, e.g. dump flood, operation. A standard electric submersible pumping system is deployed in a wellbore to draw water from an aquifer or water source zone along the wellbore. A shroud and a crossover port are used in combination with the submersible pumping system to redirect pumped water downwardly along an isolated flow path. The downward flow of pumped water is directed along the wellbore and injected into a desired, injection zone to facilitate recovery of oil or to perform other types of water flood operations. | 08-27-2009 |
20100258306 | ELECTRICAL SUBMERSIBLE PUMPING SYSTEM WITH GAS SEPARATION AND GAS VENTING TO SURFACE IN SEPARATE CONDUITS - A technique enables independent lifting of fluids in a well. The technique utilizes an electric submersible pumping system which is disposed in a wellbore and encapsulated by an encapsulating structure. The encapsulating structure has an opening through which well fluid is drawn to an intake of the electric submersible pumping system. A dual path structure is positioned in cooperation with the electric submersible pumping system and the encapsulating structure to create independent flow paths for flow of a gas component and a remaining liquid component of the well fluid. The independent flow paths also are arranged to prevent contact between the well fluid components and a surrounding wellbore wall. | 10-14-2010 |
20130277042 | Deep Deployment System for Electric Submersible Pumps - A system for deep deployment of electric submersible pumps is described. In an implementation, an electric submersible pump (ESP) power cable has a strength member that enables the ESP power cable to support itself when lowered deep into a well inside a coiled tubing. The self-supporting ESP power cable frees the coiled tubing from having to carry the weight of the ESP power cable, thereby permitting longer runs of coiled tubing to be suspended into the well. The ESP power cable and the coiled tubing can be anchored independently to a wellhead, and a computing device can monitor the weight loads on the ESP power cable and on the coiled tubing. | 10-24-2013 |
