20130035500 | METHOD OF PREPARING FUNCTIONALIZED GRAPHENE - A method of preparing functionalized graphene, comprises treating graphene with an alkali metal in the presence of an electron transfer agent and coordinating solvent, and adding a functionalizing compound. The method further includes quenching unreacted alkali metal by addition of a protic medium, and isolating the functionalized graphene. | 02-07-2013 |
20130048129 | METHOD AND APPARATUS FOR SELECTIVELY CONTROLLING FLUID FLOW - A flow control device and a method of controlling a flow, the flow control device including a flow path for a fluid therethrough and a material at least partially defining the flow path, the material operatively arranged with a surface energy less than that of the fluid for passively impeding an undesirable component of the fluid more than a desirable component of the fluid. | 02-28-2013 |
20130126184 | REACTIVE CHOKE FOR AUTOMATIC WELLBORE FLUID MANAGEMENT AND METHODS OF USING SAME - Fluid actuated chokes comprise an expandable material that expands due to an undesired fluid coming in contact with the choke. The choke includes one or more passageways through which desired fluids from a well flow unimpeded. The choke is disposed in a downhole tool as part of a downhole completion. When one or more undesired fluids enters a production stream flowing through the downhole completion and, thus, the downhole tool, and contacts the choke, the expandable material expands causing fluid flow through the passageway(s) to be restricted and, in some cases, completely closed off. Thus, the choke automatically detects and reacts, i.e., restricts fluid flow through the choke, when contacted by the undesired fluid(s). | 05-23-2013 |
20130146312 | SELF-INHIBITED SWELL PACKER COMPOUND - A downhole sealant includes a composition that includes a polymer; an absorbent material; a primary crosslink network including primary bonds between chains of the polymer; and a secondary crosslink network which is transient. A method of regulating the swell rate of the downhole sealant includes disposing a downhole sealant comprising a polymer and an absorbent material in a borehole; maintaining a primary crosslink network of the polymer; and decomposing a secondary crosslink network of the absorbent material in response to a condition to regulate the swell rate of the downhole sealant. | 06-13-2013 |
20140020910 | In Situ Plasticization of Polymers For Actuation or Mechanical Property Change - 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. | 01-23-2014 |

20150064032 | Thermoelectric Cooling Devices on Electrical Submersible Pump - An electric submersible well pump assembly includes a pump and an electrical motor filled with a dielectric lubricant. A capsule extends around a portion of the motor, defining a chamber between the capsule and the motor. A port through a side wall of the motor communicates the lubricant within the motor to the chamber. Thermoelectric devices are located within the chamber. Voltage supplied to the thermoelectric devices cools the lubricant. | 03-05-2015 |
