International Classification:

E21B021/00
E21B021/01
E21B033/13
E21B036/00
US Classification:

175 17, 166288, 166300, 166302, 175 64, 175 72
Abstract:

A method and a system for minimizing circulating fluid return losses during drilling of a well bore are disclosed. Circulating fluid, or mud, is heated above conventional temperatures for circulating fluids. The heated circulating fluid then contacts a region of a formation, in which a well bore is to be drilled, maintaining the formation at a relative higher temperature than if no special sources of heat were used to add heat to the circulating fluid. The region, at the relatively higher temperature, has a tendency to expand and to be placed in a relatively higher compressive state as compared to a formation at a lower temperature. Consequently, the use of the heated circulating fluid minimizes fracture initiation and growth and circulation fluid losses into the formation.

US Patent:

20060144591, Jul 6, 2006
Filed:

Dec 30, 2004
Appl. No.:

11/027205
Inventors:

Manuel Gonzalez - Kingwood TX, US
Robert Carpenter - Sugar Land TX, US
Jack Fralick - Alvin TX, US
James Bloys - Katy TX, US
International Classification:

E21B 33/13
E21B 36/00
US Classification:

166277000, 166057000, 166285000
Abstract:

A method and apparatus are described for creating a fluid seal in a subterranean well structure having a fluid seal defect. The method comprises introducing a meltable repair material proximate a structure in a subterranean well which has a fluid seal defect or enhanced seal capacity is required or it is desired to temporarily or permanently hydraulically isolate a portion the well or strengthen the structural integrity of well tubulars or tubular hangers. Exothermic reactant materials are located proximate the meltable repair material. The exothermic reactant material is ignited or an exothermic reaction otherwise initiated which supplies heat to and melts the meltable repair material into a molten mass. The molten mass flows and solidifies across the structure and the fluid seal defect to effect a fluid seal in the subterranean well structure or the structural integrity is enhanced. Examples of preferred exothermic reactant materials include thermite, thermate, fusible chemical reactants such as ammonium chloride and sodium nitrate, and oxidizers and accompanying hydrocarbon based fuels. Examples of preferred meltable repair materials include solder or brazing materials and eutectic metals which expand upon cooling and solidifying from a molten state.
