B29C 61/06

US Classification:

166381, 264230, 166101

Abstract:

An in situ method deploy and/or plasticize a shape-memory material in order to change the material's physical dimensions and/or mechanical properties, including a method for deploying a shape-memory polymer having a deformed or compressed shape in an environment at a first temperature, the shape memory polymer having a first glass transition temperature which is greater than the first temperature. The method also includes decreasing the glass transition temperature of shape memory polymer from the first glass transition temperature to a second glass transition temperature which is less than or equal to the first temperature; and expanding the shape memory polymer to deploy the shape memory polymer in a deployed shape.

Abstract:

A method of treating a subterranean formation penetrated by a wellbore comprises: introducing into the subterranean formation a treatment fluid comprising coated polymeric particles having a polymeric core and a curable thermoset coating disposed on the polymeric core; allowing the curable thermoset coating to cure under downhole conditions; and forming a fluid-permeable pack from the coated polymeric particles, the fluid-permeable pack reducing or substantially preventing the passage of formation particles from the subterranean formation into the wellbore while allowing passage of formation fluids from the subterranean formation into the wellbore.

Assignee:

Baker Hughes, a GE company, LLC - Houston TX

International Classification:

E21B 43/08

Abstract:

A selectively expandable screen system including a tubular having an outer surface and an inner surface defining a flow path. A screen assembly is mounted at the outer surface of the tubular. The screen assembly is formed from a compressible metal material. A selectively releasable compression device is coupled to the screen assembly. The selectively releasable compression device selectively maintains the compressible metal material in a compressed configuration.

International Classification:

E21B 43/08

Abstract:

An embodiment of a method of controlling fluid flow in a borehole in an earth formation includes: deploying a fluid flow apparatus in the borehole, the apparatus including a carrier and a shape memory component disposed at the carrier, the shape memory component including a shape memory material having a transition temperature, the shape memory material having a first shape; activating the shape memory material by causing the shape memory material to soften and change from the first shape to a second shape, the second shape configured to cause the shape memory material to control fluid flow; and deactivating the shape memory material by applying a deactivation fluid to the shape memory material, the deactivation fluid configured to cause the shape memory material to stiffen and maintain the second shape, and control fluid flow through the fluid flow apparatus.
