Publication number: 20180320477Abstract: A tool for forming a valve seat within a well that is capable of catching an obstruction will prevent flow of fluid downstream of the seat. According to one embodiment of the invention, the seat is formed by expanding a sleeve with a ring positioned around its periphery or as a subsequent step in the process. As the sleeve is expanded over the ring, the seat is formed. Once the seat is formed, an obstruction in the form of a ball or dart is dropped down to the seat. In another embodiment, the sleeve acts as a stop for a secondary valve seat which catches the obstruction. In yet another embodiment, only a portion of the sleeve is expanded and an inlet portion of the sleeve includes a valve seat.Type: ApplicationFiled: July 6, 2018Publication date: November 8, 2018Applicant: Texian ResourcesInventor: Douglas N.

Patent number: 9163494Abstract: A method for treating a well includes positioning a seat within the well that is capable of catching an obstruction which will prevent flow of fluid downstream of the seat. The seat is formed by expanding a sleeve with a ring positioned around its periphery or as a subsequent step in the process. As the sleeve is expanded over the ring, the seat is formed. Once the seat is formed, an obstruction in the form of a ball or dart is dropped down to the seat. The sleeve may also act as a stop for a secondary valve seat which catches the obstruction. The casing uphole of the seat is perforated so that fluid under pressure will enter the formation surrounding the perforations. The process is particularly useful for fracing a formation in a horizontal well where numerous stages are required to complete the stimulation of the well. There is also potential application in vertical wells.Type: GrantFiled: September 6, 2012Date of Patent: October 20, 2015Assignee: Texian ResourcesInventor: Douglas N. Love

Publication number: 20140060837Abstract: A tool for forming an obstruction in the production casing of an oil or gas well includes a sleeve adapted to be secured to the casing and having an annular abutting surface that captures a body or a cage having a solid body within the casing thereby forming an obstruction. The tool may be secured within the well either by an expandable sleeve or a collet having resilient fingers. The tool may be used as a plug to prevent flow through the production casing of the well in a well treatment process such as fracing. A process for treating a well using the tool is also presented.Type: ApplicationFiled: August 30, 2013Publication date: March 6, 2014Applicant: Texian ResourcesInventor: Douglas N. Love

Publication number: 20120085541Abstract: A mobile plant for supplying hydraulic fracturing service to a well is provided. The plant is particularly useful for wells that require multi-stage fracturing treatments, where the surface equipment may not be moved for longer times than when supplying conventional treatments. Skid-mounted equipment is used, so that the transport vehicle for the equipment can be released after delivery of the equipment to a well site. A method for marketing and executing fracturing treatments is also provided, wherein a customer is provided price data for each item included in the total cost of a fracturing treatment, along with software for calculating the total cost of a treatment to be purchased. The customer may calculate the cost of a treatment from computer-readable storage or over the internet. The customer may also monitor the fracturing treatment remotely and obtain a post-treatment report.Type: ApplicationFiled: October 12, 2011Publication date: April 12, 2012Applicant: QIP HOLDINGS, LLCInventors: Douglas N. Love, Thomas G. Hill, JR.

Patent number: 6877558Abstract: An apparatus and method is provided for locating joints in coiled tubing operations. The apparatus is adapted for running into a well on coiled tubing and for use during reverse circulating and fracturing operations. The apparatus having a central passageway for fluids, a collar locator module, a one-way valve coupled to the central passageway to allow for the flow of fluids in one direction but not the other, a port coupled to the central passageway to allow fluids to exit when the one-way valve is functioning, a movable cover module to cover the port to build up pressure in the central passageway, and a flow diverting module for permanently diverting the flow of fluids from the port to the central passageway.Type: GrantFiled: July 31, 2003Date of Patent: April 12, 2005Assignee: Halliburton Energy Services, Inc.Inventors: Michael L. Connell, Robert G. Howard, James C. Tucker, Douglas N. Love
