摘要:
A method for increasing the permeability of a geologic formation by fracturing includes the step of pumping a solution of a borohydride into a well bore. The solution may also include a basic material such as sodium hydroxide. This step may be followed by pumping a second acidic solution into the well bore.

A hydrogen cooled generator having a system for diagnosing problems associated with a seal oil system. Included is a shaft having a turbine end and a collector end; a first shaft seal located about the shaft at the turbine end; a second shaft seal located about the shaft at the collector end; a first set of sensors for measuring seal oil pressure differentials across both shaft seals; a second set of sensors for measuring seal oil temperature differentials across both shaft seals; a third sensor for measuring a hydrogen side seal oil flow rate; and a system for analyzing data collected from at least two sensors to diagnose the shaft seals.

A carbon dioxide (CO2) purity sensor package includes a fiber core, a periodic refractive index modulated fiber grating structure within the fiber core and a fiber cladding. A thermally conductive sensing layer is positioned about a portion of the fiber cladding surrounding the periodic refractive index modulated fiber grating structure. A gas chamber encloses the fiber cladding with the thermally conductive sensing layer.

A method, device, and system for resetting snapshots are provided. The reset of a snapshot incorporates the traditional snapshot delete and snapshot create operations into a single operation. Additionally, a snapshot created under the reset operation may receive an array partition from a snapshot being deleted under the same snapshot reset operation thereby retaining its identifying characteristics.

A mounting plate having an orienting portion facilitates orienting the vacuum connection opening of the mounting plate with respect to an anticipated orientation of a receptacle and electrical box. The orienting portion is optionally releasably attachable to the main body of the mounting plate which main body comprises the vacuum connection opening. The mounting plate is mounted prior to installation of the electrical receptacle in the electrical box. The orienting portion of the mounting plate facilitates orienting the vacuum connection opening in a known orientation with respect to an anticipated orientation of the electrical receptacle when inserted in the electrical box. After installation of the inlet valve and the electrical receptacle, a hose cuff having standard electrical terminals oriented with respect to the vacuum connection of the hose cuff may be simultaneously inserted into the electrical receptacle and the vacuum connection opening. The electrical terminals in the hose cuff are oriented with respect to the vacuum connection in a second known orientation corresponding to the first known orientation such that the electrical terminals mate with the electrical receptacle which has been installed in the electrical box when the vacuum connection opening receives the vacuum connection. In this manner, a hose cuff utilizing standard electrical terminals may be mated with an electrical terminal without interfering with the electrical box. Furthermore, because the orienting portion is releasably attached to the main body, the orienting portion can be removed to avoid interference with other trades.

A system for assuring subsea hydrocarbon production flow in pipelines by chilling the hydrocarbon production flow in a heat exchanger and causing solids to form, periodically removing deposits and placing them in a slurry utilizing a closed loop pig launching and receiving systems.
摘要:
A method for modifying a sealing system of a hydrogen-cooled generator includes coupling to a sealing device of the generator a contacting seal comprising a plurality of non-metallic bristles projecting from an aluminum body with tips of the bristles engaging a rotor of the generator. Another method includes removing a portion of a non-contacting seal, providing a replacement sealing device comprising an aluminum body and a plurality of non-metallic bristles projecting therefrom, and replacing the removed portion of the non-contacting seal by coupling the aluminum body to the non-contacting seal such that tips of the bristles contact the rotor. Another method includes removing an original sealing device, providing a replacement sealing device comprising an aluminum body and a plurality of non-metallic bristles projecting therefrom, and inserting the replacement sealing device into the generator such that tips of the bristles contact a rotor of the generator.
