The tool has a plurality of metal arms capable of extending radially within a secondary well casing. Each of the metal arms includes an injection electrode, a bucking electrode, and first and second monitoring electrodes. An insulating member is mounted to each metal arm. The insulating member is arranged and designed to make contact with the casing and prevent the metal arm from directly contacting the casing. A switch is provided that is capable of being electrically connected to the plurality of electrodes of one metal arm at a time. A logging cable having a plurality of wires connected at one end to the switch and a second end to instrumentation at the ground surface.Type: ApplicationFiled: April 4, 2016Publication date: March 7, 2019Inventor: Rama Rau YELUNDUR

Publication number: 20190071959Abstract: A method of producing temperature and pressure conditioned fluids using a fuel cell. The fuel cell generates an anode exhaust stream of water vapour and carbon dioxide. The water in the exhaust stream is condensed and separated to produce a stream of water and a stream of carbon dioxide. A first portion of the stream of water is heated to produce a stream of steam, which is combined with the fuel to form the anode input stream. A stream of condensed carbon dioxide is obtained by condensing at least a portion of the carbon dioxide in the stream of carbon dioxide. At least one fluid is heated and compressed to a target temperature and pressure for each fluid, the at least one fluid comprising a second portion of the stream of water or at least a portion of the condensed carbon dioxide.Type: ApplicationFiled: November 4, 2015Publication date: March 7, 2019Inventors: Jose Lourenco, Mackenzie Millar

Publication number: 20190071960Abstract: Systems and method for injection a chemical into a wellbore. A chemical injection system may comprise a first valve, a chemical line, a pilot line, an injection line, and a backflow prevention valve disposable in the injection line. A production fluid recovery system may comprise a chemical injection system, a first valve, a pilot line, an injection line, a backflow prevention valve, a production tree, a wellhead, and production tubing. A method for actuating a valve in a chemical injection system may comprise pushing a fluid into a chemical line, pressurizing a pilot line to open a first valve, pushing the fluid through the first valve, increasing pressure in the pilot line to open a second valve, pushing the fluid through the second valve, pushing the fluid through a chemical line, and injecting fluid into a wellbore from the chemical line.Type: ApplicationFiled: June 21, 2017Publication date: March 7, 2019Applicant: Halliburton Energy Services, Inc.Inventors: Paul Gregory James, Ibrahim El Mallawany

Publication number: 20190071962Abstract: An apparatus for using acoustic energy to provide operational power to a sensor of a subsea installation, such as a subsea well installation, is provided. In one embodiment, the apparatus includes a subsea installation in a body of water, with the subsea installation including a sensor and an acoustic receiver. The apparatus also includes an acoustic transmitter for transmitting acoustic waves to the acoustic receiver using the body of water as a transmission medium. The acoustic receiver is coupled to the sensor so that the sensor can be powered with electricity generated from the acoustic waves received at the acoustic receiver from the acoustic transmitter. Additional systems, devices, and methods are also disclosed.Type: ApplicationFiled: September 6, 2017Publication date: March 7, 2019Inventors: Emanuel Gottlieb, Rolf Rustad, Alek Cywinski

Publication number: 20190071963Abstract: An interlock system for use in a wellbore and method of using same, including a plurality of sensors configured to detect physical conditions within a wellbore. The sensors may be absolute locational sensors or relative locational sensors. Electronic signals are generated when sensors detect corresponding physical conditions. A processor derives location information from the electronic signals, and verifies location by comparison to pre-programmed reference information for each sensor. A trigger signal is generated when at least two location information have been verified, which is used to activate a downhole event. A timer may also be set with a calculated time delay before the trigger signal is generated. The interlock system operates independent of connection to any device at the surface of a wellbore, and may be attached to any equipment for deployment down a wellbore.Type: ApplicationFiled: September 5, 2017Publication date: March 7, 2019Applicant: IdeasCo LLCInventor: Joseph Sites
