Patent number: 7866392Abstract: A well casing cementing apparatus includes a housing and an inner assembly of movable parts. The housing includes a cementing port and a packer on its outer surface below the cementing port. The inner assembly includes three movable parts comprising a closing sleeve for closing the cementing port after a cementing operation, a closing sleeve seat for moving the closing sleeve and a packer setting sleeve for setting the packer. A rupture disk is provided closing the cementing port in a run in condition and is selected to have a rupture pressure at or above a pressure selected for setting the packer. An expandable collet on a lower end of the housing permits the closing sleeve and the setting sleeve to be pumped out the lower end of the housing, but prevents the pumped out parts from moving back into the housing, e.g. during production of fluids from the well.Type: GrantFiled: December 12, 2007Date of Patent: January 11, 2011Assignee: Halliburton Energy Services Inc.Inventors: Henry Rogers, Brett Fears

Publication number: 20100276204Abstract: A vibrating tool comprising a hammer and valve that oscillate axially inside a housing to produce vibrations solely in response to fluid flow through the tool at an operating flow rate. The valve is supported by a spring that resists compression until a minimum operating flow rate is achieved, and hammer is also spring-loaded. When the valve strokes down and engages the hammer, flow through the hammer is restricted. Increased fluid pressure pushes the hammer down away from the valve, resulting in a sudden decrease in pressure, allowing both the hammer and valve to rebound and create vibrational impacts. The cycle repeats continuously as long as an adequate flow rate is maintained.Type: ApplicationFiled: April 30, 2010Publication date: November 4, 2010Applicant: THRU TUBING SOLUTIONS, INC.Inventors: Michael L. Connell, Andrew M. Ferguson, Stanley W. Loving, Brett A. Fears, James L. Jobe

Patent number: 7322413Abstract: A method for controlling a fluid pressure applied to a cementing plug comprises disposing the cementing plug within a casing string to define a trapped volume of fluid within the casing string, isolating a portion of the trapped volume of fluid adjacent the cementing plug to define an isolated volume of fluid, and relieving the fluid pressure within the isolated volume of fluid at a first rate sufficient to prevent damage to or inadvertent release of the cementing plug. An apparatus for relieving fluid pressure within a casing string being run into a well bore comprises at least one equalizer valve connected to a work string extending into the casing string, and a sealing device disposed above the equalizer valve to seal an annular space formed between the work string and the casing string.Type: GrantFiled: July 15, 2005Date of Patent: January 29, 2008Assignee: Halliburton Energy Services, Inc.Inventors: Henry E. Rogers, David Durward Szarka, Brett A. Fears

Patent number: 7255162Abstract: The present invention relates to subterranean cementing operations, and more particularly to an apparatus useful in loading cementing plugs and darts into tubulars, and methods of using such apparatus in subterranean cementing operations. An example of a method of the present invention is a method of placing a compressible object having a cross-section within a tubular, including the steps of: reducing the cross-section of the compressible object; placing the compressible object with the reduced cross-section in a tubular; and releasing the compressible object within the tubular. Another example of a method of the present invention is a method of reducing the radial cross-section of a compressible object. Other examples of apparatus of the present invention include apparatus for placing a compressible object into a tubular.Type: GrantFiled: May 7, 2004Date of Patent: August 14, 2007Assignee: Halliburton Energy Services, Inc.Inventors: Michael D.
