Patent number: 7353879Abstract: A disposable downhole tool or a component thereof comprises an effective amount of biodegradable material such that the tool or the component thereof desirably decomposes when exposed to a wellbore environment. In an embodiment, the biodegradable material comprises a degradable polymer. The biodegradable material may further comprise a hydrated organic or inorganic solid compound. The biodegradable material may also be selected to achieve a desired decomposition rate when the tool is exposed to the wellbore environment. In an embodiment, the disposable downhole tool further comprises an enclosure for storing a chemical solution that catalyzes decomposition. The tool may also comprise an activation mechanism for releasing the chemical solution from the enclosure. In various embodiments, the disposable downhole tool is a frac plug, a bridge plug, or a packer.Type: GrantFiled: March 18, 2004Date of Patent: April 8, 2008Assignee: Halliburton Energy Services, Inc.Inventors: Bradley L.

Patent number: 7093664Abstract: The present invention is directed to disposable composite downhole tool formed of a resin-coated fiber. The fiber is formed of a degradable polymer, such as a poly(lactide) or polyanhydride. The resin is formed of the same degradable polymer as the fiber. It chemically bonds to the fiber, thereby making a strong rigid structure once cured. The fiber may be formed into a fabric before being coated with the resin. Alternatively, the fiber is formed of a non-biodegradable material.Type: GrantFiled: March 18, 2004Date of Patent: August 22, 2006Assignee: Halliburton Energy Services, Inc.Inventors: Bradley L.

Patent number: 6666275Abstract: A retrievable bridge plug assembly having an internal “pump through” bypass passage and a wedge assembly, slips and seals disposed thereon. A retrieving tool is provided for running, setting, releasing and retrieving the bridge plug assembly. A tubing sensor is included to prevent setting of the bridge plug assembly in improper size tubing. When the bridge plug is properly located, the wedge assembly can actuated by manipulation of the retrieving tool to force the slips radially outward into gripping engagement with the well tubular and to force the seals into sealing engagement with the well tubular. A ball valve on the bridge plug assembly is movable to selectively open and close the bypass passage. The retrieving tool can maintain the valve and passageway open to facilitate circulation during run in and setting and also open during retrieving for pressure equalization. A service packer can be connected to and run with the bridge plug assembly.Type: GrantFiled: August 2, 2001Date of Patent: December 23, 2003Assignee: Halliburton Energy Services, Inc.Inventors: Kenneth G. Neal, Kevin T. Berscheidt, Don S. Folds, Ronald L. Hinkie, Loren C. Swor, Brian K. Wilkinson
