Methods And Apparatus For Wellbore Enhancement

View page
US Patent:
20100089574, Apr 15, 2010
Filed:
Oct 8, 2009
Appl. No.:
12/575857
Inventors:
Thomas W. Wideman - Milton MA, US
Jared M. Potter - Redwood City CA, US
Donald S. Dreesen - Los Alamos NM, US
Robert M. Potter - Rio Rancho NM, US
Assignee:
Potter Drilling, Inc. - Redwood City CA
International Classification:
E21B 43/24
E21B 43/00
E21B 43/267
E21B 43/26
US Classification:
1662721, 166313, 1662802, 1663081
Abstract:
Methods for enhancing existing wells, such as increasing the diameter of an existing well by hydrothermal spallation are provided. Such methods may include providing a housing comprising a reaction chamber and a catalyst element held within the reaction chamber, providing at least one jet nozzle, contacting one or more unreacted fluids or solids with the catalyst element, wherein the unreacted fluid or solid is adapted to react with the catalyst element, thus generating a reacted fluid, and emitting the reacted fluid through the at least one nozzle, wherein the at least one nozzle may be directed to a production zone of an internal wall of the existing well.

US Patent:
20100089576, Apr 15, 2010
Filed:
Oct 8, 2009
Appl. No.:
12/575839
Inventors:
THOMAS W. WIDEMAN - MILTON MA, US
JARED M. POTTER - REDWOOD CITY CA, US
DONALD S. DREESEN - LOS ALAMOS NM, US
ROBERT M. POTTER - RIO RANCHO NM, US
Assignee:
Potter Drilling, Inc. - Redwood City CA
International Classification:
E21B 43/241
E21B 7/14
US Classification:
1662726, 175 15
Abstract:
Methods and apparatus for spalling a geological formation, for example to thermally drill a wellhole, are provided. Such methods may include providing a housing comprising a reaction chamber and a catalyst element held within the reaction chamber, providing at least one jet nozzle, contacting one or more unreacted fluids or solids with the catalyst element, wherein the unreacted fluid or solid is adapted to react over the catalyst element, thus generating a reacted fluid, and emitting the reacted fluid through the at least one nozzle, wherein the at least one nozzle is directed to an excavation site within or on the geological rock formation, thereby creating spalls and/or a reacted rock region.

US Patent:
20100218993, Sep 2, 2010
Filed:
Oct 8, 2009
Appl. No.:
12/575823
Inventors:
Thomas W. Wideman - Milton MA, US
Jared M. Potter - Redwood City CA, US
Donald S. Dreesen - Los Alamos NM, US
Robert M. Potter - Rio Rancho NM, US
Jason Unzelman-Langsdorf - Redwood City CA, US
International Classification:
E21B 7/00
US Classification:
175 17
Abstract:
Methods and apparatus for excavation of a borehole in a geological formation are provided. Such methods may include providing a thermal system capable of providing substantially hot fluid, and comprising at least one jet nozzle, providing a mechanical drilling system comprising a drill bit, directing the substantially hot fluid through the jet nozzle towards the geological formation causing an altered portion of geological formation to form, and removing the altered portion using the drill bit, thereby creating cuttings and producing a borehole in the geological formation.

US Patent:
20130264118, Oct 10, 2013
Filed:
Nov 9, 2012
Appl. No.:
13/672842
Inventors:
Jared M. Potter - San Carlos CA, US
Donald S. Dreesen - Los Alamos NM, US
Robert M. Potter - Redwood City CA, US
Jason Unzelman-Langsdorf - Redwood City CA, US
International Classification:
E21B 10/60
US Classification:
175 17
Abstract:
Methods and apparatus for excavation of a borehole in a geological formation are provided. Such methods may include providing a thermal system capable of providing substantially hot fluid, and comprising at least one jet nozzle, providing a mechanical drilling system comprising a drill bit, directing the substantially hot fluid through the jet nozzle towards the geological formation causing an altered portion of geological formation to form, and removing the altered portion using the drill bit, thereby creating cuttings and producing a borehole in the geological formation.

US Patent:
8235140, Aug 7, 2012
Filed:
Oct 8, 2009
Appl. No.:
12/575852
Inventors:
Thomas W. Wideman - Milton MA, US
Jared M. Potter - Redwood City CA, US
Donald Dreesen - Los Alamos NM, US
Robert M. Potter - Rio Rancho NM, US
Assignee:
Potter Drilling, Inc. - Redwood City CA
International Classification:
E21B 7/00
US Classification:
175 11, 175 15
Abstract:
Methods and apparatus for spalling a material, for example to thermally drill a wellhole, are provided. Such methods may include directing a fluid having a temperature greater than about 500 C. above the ambient temperature of the material and less than about the temperature of the brittle-ductile transition temperature of the material to a target location on the surface of the material, wherein the fluid produces a heat flux of about 0. 1 to about 50 MW/mat an interface between the fluid and the target location, and thereby creating spalls of the material.
