Method and apparatus to provide electrical connection in a wellhead for a downhole electrical device
Patent number: 7918271Abstract: Wellhead assembly and method for providing a power connection to a downhole electrical device, such as a heater. Pressure-containing wellhead body members enclose a vertical wellbore and support therein an isolated tubing hanger and a grounding tubing hanger. The isolated tubing hanger suspends a conducting tubing string, while the grounding tubing hanger suspends a grounding tubing string concentrically spaced from the conducting tubing string. The isolated tubing hanger has an outer housing, an inner electrically conducting portion supported by the outer housing operative to provide electrical connection with, and suspend, the conducting tubing string, and insulation between the housing and conducting portion to electrically isolate the housing portion. Hot electrical connection is made for electrical connection to the conducting portion of the isolated tubing hanger or the conducting tubing string.Type: GrantFiled: June 29, 2009Date of Patent: April 5, 2011Assignee: Stream-Flo Industries Ltd.Inventors: Abram Khazanovich, Irina Khazanovich, Nathan Kwasniewski -

Method and apparatus to provide electrical connection in a wellhead for a downhole electrical device
Patent number: 7410002Abstract: Wellhead assembly and method for providing power connection to downhole electrical device. Wellhead body members support vertically stacked isolated tubing hanger and grounding tubing hanger. The isolated tubing hanger suspends a conducting tubing string, while the grounding tubing hanger suspends a grounding tubing string concentrically spaced from the conducting tubing string. The isolated tubing hanger has an outer housing, an inner electrically conducting portion supported by the outer housing to provide electrical connection with, and suspend, the conducting tubing string, and insulation between the housing and conducting portion to electrically isolate the housing. Hot electrical connection is made through a conduit in the wellhead body member, for electrical connection to the conducting tubing string. Grounding connection is provided to the wellhead body members.Type: GrantFiled: August 5, 2004Date of Patent: August 12, 2008Assignee: Stream-Flo Industries, Ltd.Inventors: Abram Khazanovich, Irina Khazanovich, Nathan Kwasniewski -

Patent number: 7069987Abstract: The invention provides a casing adapter tool which connects and seals to a casing pipe at its lower end and to production or service equipment at its upper end, and is used with well servicing equipment, such as is involved in fracturing. The casing adapter tool includes a generally tubular casing adapter body having an upper end and a lower end, and is formed with a central bore extending therethrough. The central bore provides a profile which forms a casing seal chamber at the lower end, and a barrier seal chamber located thereabove. The barrier seal chamber is formed with a profile to accommodate and seal to a first removable pressure barrier on removal of any well servicing equipment. Most preferably, the barrier seal chamber has a profile sized to provide full bore access to the casing pipe and to accommodate and seal to the first removable pressure barrier which is of a threaded, latched or snap ring type check valve or plug.Type: GrantFiled: February 6, 2004Date of Patent: July 4, 2006Assignee: Stream-Flo Industries, Ltd.Inventors: Nathan Kwasniewski, Keith David Farquharson, Bob McGuire, John Henry Whelan

Method and apparatus to provide electrical connection in a wellhead for a downhole electrical device
Publication number: 20050051341Abstract: Wellhead assembly and method for providing a power connection to a downhole electrical device, such as a heater or pump. Pressure-containing wellhead body members enclose a vertical wellbore and support, in vertically stacked relationship, an isolated tubing hanger and a grounding tubing hanger. The isolated tubing hanger suspends a conducting tubing string, while the grounding tubing hanger suspends a grounding tubing string concentrically spaced from the conducting tubing string. The isolated tubing hanger has an outer housing, an inner electrically conducting portion supported by the outer housing operative to provide electrical connection with, and suspend, the conducting tubing string, and insulation between the housing and conducting portion to electrically isolate the housing portion. A conduit in a wellhead body member provides access to the vertical wellbore proximate the isolated tubing hanger.Type: ApplicationFiled: August 5, 2004Publication date: March 10, 2005Applicant: Stream-Flo Industries, Ltd.Inventors: Abram Khazanovich, Irina Khazanovich, Nathan Kwasniewski -
