Patent number: 8061419Abstract: A wellhead connection for connecting and sealing to a casing, including an upper head housing accommodating the upper end of the casing in its central bore, a stop shoulder in the central bore to allow the upper head housing to rest on the upper end of the casing, and a seal profile section formed at the lower end of the central bore below the stop shoulder. The wellhead connection is configured such that, first connecting the slip housing and bottom ring with a bottom connector energizes slip connectors into gripping engagement with the casing and locks the slip housing and bottom ring around the casing, while thereafter connecting the upper head housing and the bottom ring with a top connector energizes the metal seal ring so as to radially compress the metal seal ring against the casing to form a metal seal.Type: GrantFiled: November 13, 2008Date of Patent: November 22, 2011Assignee: Stream-Flo Industries Ltd.Inventors: Abram Khazanovich, Irina Khazanovich

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 -

Publication number: 20090223661Abstract: A casing cap to seal the annulus formed between an upper end of an outer casing and an inner casing. An annular casing cap housing is formed in split portions which when joined at their splits form the casing cap housing to cover and seal the annulus. The joined casing cap split portions form a side wall which surrounds the outer casing. The upper end forms an annular top section adapted to rest on the upper end of the outer casing, cover the annulus and form an upper annular seal to the inner casing. The lower end is adapted to form a mechanical connection, preferably non-welded, to the outer casing and to form an annular seal to the outer casing. Connectors between the casing cap split portions clamp together the sealing surfaces of the casing cap split portions with the sealing element to form pressure-containing, non-welded seals.Type: ApplicationFiled: March 6, 2009Publication date: September 10, 2009Applicant: Stream-Flo Industries Ltd.Inventors: Abram KHAZANOVICH, Irina Khazanovich

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: 6595278Abstract: The assembly functions to clamp onto and frictionally engage the polished rod of a well's rod string, with sufficient force to suspend the string from the wellhead. The assembly comprises an annular body forming opposed, radial, internally threaded side openings extending from its outer circumferential surface to its central vertical bore. An externally threaded locking member is positioned in each side opening and protrudes externally. The locking members can be manually threaded inwardly to engage the polished rod. An external leverage assembly is anchored to the body and engages one of the locking members. This leverage assembly can be manually turned to tighten the locking member against the polished rod with powerful axial force to provide enhanced gripping.Type: GrantFiled: January 17, 2002Date of Patent: July 22, 2003Assignee: Stream-Flo Industries Ltd.Inventors: Tony M. Lam, Abram Khazanovich, Irina Khazanovich
