Publication number: 20220154546Abstract: A method for permanently sealing or bridging perforations disposed in a wellbore that was previously subjected to various completion operations and comprises a plurality of perforated sections comprising a plurality of perforations. In one embodiment, the method comprises configuring a ball injector or multiple ball injectors at the surface of the wellbore, pumping non-degradable perforation ball sealers into the perforated sections via the ball injector, wherein the non-degradable perforation ball sealers permanently seal all perforated sections in the wellbore, and monitoring pressure within the wellbore during operation to determine a successful seal of all the perforated sections.Type: ApplicationFiled: November 19, 2020Publication date: May 19, 2022Applicant: Ely and Associates, LLCInventor: John W.

Patent number: 9771784Abstract: A method for re-fracturing of wells having perforated casing that were previously fractured is provided. The method employs degradable ball sealers having a density near that of the injection fluid such that high seating efficiency of balls on perforations is attained. The balls degrade at varying rates, so that some intervals are opened for fracturing while other intervals are still blocked by ball sealers. After fracturing of an interval, the interval may by shut-off by ball sealers that degrade at a much slower rate or that do not degrade. The method may be applied to proppant fracturing or acid fracturing.Type: GrantFiled: October 23, 2015Date of Patent: September 26, 2017Assignee: Ely and Associates Corp.Inventor: John W. Ely

Patent number: 6945327Abstract: Method is provided for increasing the productivity of gas wells producing from reservoirs where retrograde condensation occurs around the wells. An oil-wetting surfactant is injected in a solvent to oil wet the formation for a selected distance around a well or a hydraulic fracture intersecting the well. A pre-flush liquid, such as carbon dioxide, alcohol or similar products and mixtures thereof, may be used to reduce water saturation before injection of the surfactant. The method may also be applied to increase the productivity of oil wells producing from reservoirs where breakout of solution gas occurs near the well.Type: GrantFiled: February 11, 2003Date of Patent: September 20, 2005Assignee: Ely & Associates, Inc.Inventors: John W. Ely, Bradley C. Wolters, William D. McCain

Patent number: 4265311Abstract: A fracturing fluid composition consisting essentially of a viscous aqueous solution having a high concentration of cations, an anionic or nonionic viscosifier imparting a high viscosity to the composition, and an anionic, polymeric fluid loss material which is substantially insoluble in the aqueous solution, and is soluble in fresh water substantially free of the cations in the fracturing fluid.In the method of fracturing using the fracturing fluid compositions of the invention, the composition is injected into the fracture via the well bore to enlarge and/or extend the fracture. Completion of fracturing is followed by injection of fresh water into the fracture from the well bore to dissolve the anionic, polymeric fluid loss material, and displace the fracturing fluid composition into the formation upon continuation of a water flood operation.Type: GrantFiled: November 5, 1979Date of Patent: May 5, 1981Assignee: Halliburton CompanyInventor: John W.
