Filed:

Dec 7, 2012

Appl. No.:

13/708206

Inventors:

David Kamensky - West Chester OH, US
John Andrew Westerheide - Houston TX, US
Christopher Edward Wolfe - Niskayuna NY, US

Assignee:

GENERAL ELECTRIC COMPANY - Schenectady NY

International Classification:

E21B 43/26

US Classification:

1663081

Abstract:

A fracturing system is described. The system includes an electric motor-driven pumping sub-system, configured to pump a pressurized fracturing fluid into at least one wellbore, under high pressure conditions sufficient to increase the downhole pressure of the wellbore, to exceed that of the fracture gradient of the solid matter surrounding the wellbore. The system also includes an electric power generation sub-system that provides energy to the pumping sub-system. The electric power generation sub-system includes a multitude of electric motors that are powered by a single electrical feed source. A related process for extracting hydrocarbons from a reservoir rock formation by the fracturing operation is also described.

Abstract:

A seal assembly for a rotary machine includes a seal bearing face that opposes a rotating component of the machine and a slide device coupled with the seal bearing face. The slide device axially moves toward the rotating component responsive to pressurization of the rotary machine. The slide device includes cross-over ports and the seal bearing includes feed ports. The feed ports extend through the seal bearing face to form aerostatic portions of a film bearing between the seal bearing face and the rotating component. The seal bearing face and/or the rotating component has a non-planar surface that, during rotating motion of the rotating component relative to the face of the seal bearing face, forms aerodynamic portions of the film bearing.

Abstract:

Coating systems for a cooled turbine blade tip, such as a metal turbine blade tip, are provided. The coating system includes an abrasive layer overlying the surface of the turbine blade tip. One or more buffer layers may additionally be disposed between an outer surface of the blade tip and the abrasive layer. The coated blade tip can be used with a ceramic matrix composite (CMC) shroud coated with an environmental barrier coating (EBC) to provide improved cooling to the tip so as to lengthen oxidation time of the abrasive layer and reduce blade tip wear. Methods are also provided for forming the cooled blade tip and applying the coating system onto the cooled turbine blade tip.
