| 20090038799 | System, Method, and Apparatus for Combined Fracturing Treatment and Scale Inhibition - A treatment fluid for a subterranean formation includes a carrier fluid and an amount of particles including a granular scale inhibitor. The carrier fluid includes a hydratable gel fluid, a crosslinked gel fluid, an acid-based fluid, an oil-based fluid, and/or a visco-elastic surfactant. The particles include a proppant impregnated with the scale inhibitor, a solid particle formed largely from the scale inhibitor, or both. The proppant includes scale inhibitor adsorbed on porous surfaces within the proppant, and/or a porous proppant with scale inhibitor embedded in the bulk porosity of the proppant. The scale inhibitor is present in an amount between about 1% and 5% of a total weight of particles. The particles include scale inhibitor at a sufficient concentration and dissolution rate to provide acceptable scale inhibitor concentrations in produced fluids for production volumes exceeding 500 pore volumes. | 02-12-2009 |

| 20080287323 | Treatment and Reuse of Oilfield Produced Water - The invention discloses treatment and reuse of oilfield produced water. A method of inhibiting enzymes/bacteria in an aqueous medium for viscosification comprises contacting the aqueous medium with a denaturant and/or a bactericide and thereafter mixing a gelling agent in the aqueous medium. The viscosified fluid can be used as a well treating fluid for fracturing and other applications. A well treatment fluid comprises a metal denaturant and/or a bactericide and a gelling agent in an amount effective to viscosify the fluid. Also disclosed is oilfield produced water denatured with from 1 to 2000 ppm by weight of a zirconium compound. | 11-20-2008 |

| 20100272095 | Device and Method for Controlling the Creation of a User Channel Connection in a Communication System and Associated Communication System, Digital Storage Medium, Computer Program Product, and Computer Program - In order to be able to control the creation of a user channel connection in a communication system using wireless communication between at least one mobile part and one wired part in such a way that a user channel connection is established more quickly upon a connection request indicated by the mobile part or the wired part for the purpose of transmitting user data and, at the same time, due to market requirements, no synchronization pulses are sent by the wired part in the idle state, an initiating device of the communication system (for example, for an incoming call: base station; for an outgoing call: mobile part) sends, from an asynchronous idle state, synchronization pulses (SB) to all available physical resources. Due to the plurality of the sent, available synchronization pulses (SB), rapid synchronization is ensured because the probability is sufficiently increased thereby that a pulse will fall in the search window of a receiver. | 10-28-2010 |

| 20090326794 | Method for selecting elements in a driver information system or in a navigation system or in a mobile terminal - A method for destination selection in a navigation system in which each destination from a totality of all destinations is defined by destination parameters and a set of possible destinations from the totality of all destinations is limited step-wise due to the input of individual characters for one parameter. When inputting the characters, a switch may be made from one destination parameter to an input of a character for another parameter. | 12-31-2009 |
