Filed:

Oct 24, 2012

Appl. No.:

13/659323

Inventors:

Michael L. FRIPP - Carrollton TX, US
Liang ZHAO - Carrollton TX, US
Frederic FELTEN - Corinth TX, US

Assignee:

HALLIBURTON ENERGY SERVICES, INC. - Houston TX

International Classification:

E21B 34/06

US Classification:

166373, 166316

Abstract:

A variable flow resistance system for use with a subterranean well can include a structure which displaces in response to a flow of a fluid composition, whereby a resistance to the flow of the fluid composition changes in response to a change in a ratio of desired to undesired fluid in the fluid composition. Another system can include a structure which rotates in response to flow of a fluid composition, and a fluid switch which deflects the fluid composition relative to at least two flow paths. A method of variably resisting flow in a subterranean well can include a structure displacing in response to a flow of a fluid composition, and a resistance to the flow of the fluid composition changing in response to a ratio of desired to undesired fluid in the fluid composition changing. Swellable materials and airfoils may be used in variable flow resistance systems.

International Classification:

E21B 34/08

US Classification:

166319

Abstract:

Fluid flow influencer devices capable of affecting fluid flow for fluid selection are described. Fluid flow influencer devices may affect fluid flowing into a turbulence, such as a vortex, having a structure that is usable to restrict fluid flow in a flow path of a chamber by different amounts based on at least one property of the fluid. The fluid flow control device may be in an autonomous fluid selector, such as a diverter, a vortex-causing device, or a whisker. Fluid properties based on which the flow influencer device can select fluid can include fluid density, fluid velocity, fluid viscosity, and Reynolds number of the fluid flow.

Assignee:

HALLIBURTON ENERGY SERVICES, INC. - HOUSTON TX

International Classification:

E21B 41/00

US Classification:

166228, 166227

Abstract:

Certain aspects and embodiments of the present invention are directed to a porous medium screen that can be disposed in a wellbore through a fluid-producing formation. The porous medium screen can include a porous medium and a retaining structure. The porous medium can be a material having one or more pores. The pores can be adapted to allow a fluid to flow through the porous medium and to prevent particles from flowing through the porous medium. The retaining structure can be adapted to retain the porous medium in a position circumferentially surrounding a section of a tubing string and to prevent expansion of the porous medium. The retaining structure can include a shroud and one or more stoppers. The shroud can be adapted to circumferentially surround the porous medium. Each stopper can be adapted to circumferentially surround the section of a tubing string at an edge of the porous medium.

Abstract:

Embodiments of the present disclosure describe a mixing nozzle, system implementing the mixing nozzle, and corresponding method of use. The mixing nozzle includes a housing defining a mixing chamber that has a sidewall separating a first end from a second end. A set of tangential feed conduits, which are oriented tangentially to the mixing chamber, extend outwardly from the mixing chamber, through the housing. An outlet orifice is located in the second end, which is one end of an exit channel extending through the housing.
