20080224413 | Sealing material to metal bonding compositions and methods for bonding a sealing material to a metal surface - A downhole well tool having a component with a metal surface to which a sealing material is adhered is disclosed. The sealing material is bonded to the metal surface through the use of an energetic material disposed between the sealing material and the metal surface. Upon activation or initiation of the energetic material, the sealing material becomes bonded to the metal surface. A plastic layer may be disposed between the sealing material and the metal surface to facilitate bonding sealing material to the metal surface. The energetic material is used to bond the plastic layer to the metal surface and may be used to bond the plastic layer to the sealing material. | 09-18-2008 |

A method of deploying an apparatus using such a composition may include placing the apparatus at a suitable location in a wellbore and exposing the composition to the selected energy to deploy the apparatus in the wellbore. | 12-04-2008 |
20090101341 | Water Control Device Using Electromagnetics - An apparatus for controlling a flow of fluid in a well includes a flow control device and a generator that generates electrical energy in response to a flow of an electrically conductive fluid. The flow control device may include an actuator receiving electrical energy from the generator, and a valve operably coupled to the actuator. The actuator may be configured to operate after a preset value for induced voltage is generated by the generator. The generator may use a pair of electrodes positioned along a flow path of the electrically conductive fluid to generate electrical energy. In one arrangement, one or more elements positioned proximate to the electrodes generate a magnetic field along the flow path of the electrically conductive fluid that causes the electrodes to generate a voltage. In another arrangement, the electrodes create an electrochemical potential in response to contact with the electrically conductive fluid. | 04-23-2009 |
