International Classification:

E21B 33/12

US Classification:

166387, 277336

Abstract:

A swell controlling arrangement includes a swellable member configured to swell upon exposure to a swell inducing fluid, and an acidic material that is configured to form an acidic environment. The swell controlling arrangement is configured to preferentially expose the swellable member to the acidic environment when the swellable member and the acidic material are exposed to the swell inducing fluid.

International Classification:

C09K 8/00
E21B 23/00

US Classification:

166381, 507219

Abstract:

A method for deploying a shape memory polymer includes disposing a shape memory polymer having a deformed 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.

US Classification:

95241, 96219, 977734, 977742

Abstract:

A system for separating fluids of a fluid mixture including a filter element operatively arranged for enabling a first component of a fluid mixture to flow therethrough while impeding flow of at least one other fluid component of the fluid mixture. An additive is configured to improve a first affinity of the filter element for the first component relative to a second affinity of the filter element for the at least one other fluid component of the fluid mixture. A method of separating fluids is also included.

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.

International Classification:

C09K 702

US Classification:

507140

Abstract:

A drilling fluid having a brine base fluid, aluminum chlorohydrate as a viscosifying agent, an alkoxylated surfactant, and an amphoteric polymer encapsulant has been found to have excellent viscoelasticity and suspension characteristics. Surprisingly, it has been discovered that a synergistic effect is present between the aluminum chlorohydrate and the surfactant such that less of each component is required when both are used together to suspend the same amount of solids, than if one or the other is used separately.
