    摘要: A thickened aqueous composition is delivered to a subterranean location accessible via a wellbore by steps of i. providing a biphasic aqueous mixture comprising two aqueous solutions which, at surface temperature and pressure, are able to co-exist as separate aqueous phases in contact with each other, ii. pumping said biphasic aqueous system down the wellbore to the subterranean location, and iii. converting the biphasic mixture below ground so that its phases combine into a single aqueous phase which is more viscous than the biphasic mixture. The two phases of the aqueous biphasic mixture contain dissolved solutes which segregate between the two phases such that at least one first solute is present at a greater concentration in the first aqueous phase than in the second aqueous phase while at least one second solute is present at a greater concentration in the second aqueous phase than in the first aqueous phase. The solute in the first phase may be a thickening polymer or other thickening material such as viscoelastic surfactant. The solute in the second phase may be a different polymer, surfactant or salt. Conversion to a single phase may be carried out in various ways including dilution, change in pH, change in salinity, increase in temperature and adsorption of one solute onto formation rock.

    摘要: A system for monitoring a sensor includes a GUI (Graphical User Interface) such as a WebPage embedded in the sensor. The GUI is configured to display information relating to the sensor from a user computer connectable to the sensor via an Ethernet connection and having an internet web browser for accessing the WebPage of the sensor. A computer-readable medium is embedded within the sensor and has stored therein computer-usable instructions for a processor. These instructions, when executed by the processor, cause the processor to generate the GUI.

    摘要: The present invention is a method for treating a subterranean wellbore. More specifically, the invention is a method for removing wellbore solids. A first, polymer containing fluid is placed in the solids bed. A second, viscosifying fluid is then placed into the solids bed thereby agitating the solids in the bed and causing the formation of a gel capsules when mixed with the biopolymer fluid. These gel capsules are capable of trapping or entraining the agitated solids. The gel capsules typically have a relatively high volume and a relatively low density, thereby making their removal from the wellbore easier.

    摘要: An ion implanter for low energy ion implantation includes an ion beam generator, a older for supporting a workpiece, such as a semiconductor wafer, and a voltage source electrically connected to the workpiece. The ion beam generator includes an ion source for generating ions and an extraction electrode having an extraction voltage applied thereto for accelerating the ions to form an ion beam. The voltage source applies to the workpiece a bias voltage that is of opposite polarity and smaller magnitude than the extraction voltage. The ions in the ion beam are implanted in the workpiece with an energy that is a function of the difference between the extraction voltage and the bias voltage.

    摘要: Tubewaves are used to transmit an indication of the depth at which a condition is detected in a well. In particular, the depth is calculated based on the difference in arrival time at the surface of a first tubewave which propagates directly upward in the borehole and a second tubewave which initially travels downward and is then reflected upward. The tubewaves may be generated by a canister designed to implode at a certain pressure. The canister is carried downhole by gravity and the fluid being pumped. At a depth at which its pressure tolerance is exceeded, it implodes and generates the tubewaves. An analyzer at the surface detects the tubewaves and generates a pressure versus depth profile of the well. Canisters may be acoustically tagged in order to generate tubewaves having particular frequency and amplitude characteristics. Canisters may also be configured to produce multiple implosions.
