Title: Producer well plugging for in situ combustion processes
Inventor: DREHER WAYNE REID JR
IPC: E21B33/13
Filed: 2009-11-13
Granted: 2011-05-03
Abstract: Methods and apparatus relate to controlling location of inflow into a production well during in situ combustion. The production well includes intervals closable to the inflow at identified times. Once a combustion front from the in situ combustion passes one of the intervals, a blockage conveyed from surface into the production well forms a barrier to the inflow at the interval that has been passed by the combustion front. An example of the blockage includes a cement plug delivered through coiled tubing into the production well, which may include production tubing that defines the intervals based on at least two consecutive alternating lengths of solid wall sections and slotted or perforated sections of the production tubing.

Granted: 2016-01-05
Abstract: For injecting e.g water into ground formation around a borehole, and for superimposing pulses onto the outflow of the injected water, it is important that the puses have a rapid rise-time. A piston is connected to a pulse-valve of the tool. A bias spring urges the piston towards its closed position. The piston is urged towards the open position by a differential PDAF between the supplied accumulator-pressure and the in-ground formation-pressure. When the pulse-valve is open, the PDAF is falling, until the force of the spring closes the pulse-valve.    Then the PDAF rises, but now the PDAF acts over only a small area of the piston. When the PDAF is high enough to ease the pulse-valve open, suddenly the whole area of the piston is exposed to the PDAF, whereby the pulse-valve opens violently.

Abstract: Techniques for hardware accelerated caret rendering are described in which a system based caret is emulated using hardware acceleration technology. The hardware accelerated caret can be rendered using dedicated graphics processing hardware to look and feel like a system caret. This can involve using pixel shaders to produce the hardware accelerated caret and a employing a back-up texture to remove the caret after it is drawn and cause the caret to blink. In addition, rendering of the caret can be coordinated with other animations and/or other presentations of a frame buffer to piggy back drawing of the caret onto other drawing operations. This can reduce the number of times the frame buffer is presented and therefore improve performance.

Abstract: A system and method for transforming a software application comprising binary code and optionally associated data, from an original form to a more secure form. The method includes performing a combination of binary transmutations to the application, and interlocking the transmutations by generating and placing interdependencies between the transmutations, wherein a transmutation is an irreversible change to the application. Different types of the transmutations are applied at varied granularities of the application. The transmutations are applied to the application code and the implanted code as well. The result is a transformed software application which is semantically equivalent to the original software application but is resistant to static and/or dynamic attacks.

Abstract: A method for overlapping a delivery of at least one independently measured material with a delivery of a main material from a source location to a target location during a material transfer process. This method includes the steps of inputting a target amount for a main material to be delivered from a source destination to a target destination, wherein the main material is delivered directly to the target location using a load-cell system, and wherein a final target batch weight is defined as the sum of a target amount for the main material and an aggregate sum of target amounts for the independently measured materials to be delivered. The final target batch weight is updated after the delivery of each independently measured material, while the main material is still being delivered, to reflect any delivery variation from the original independently measured material target amounts.

Abstract: Disclosed are charging algorithms implementable in an external charger for controlling the charging of both an external battery in the external charger and an implant battery in an implantable medical device. Because full-powered simultaneous charging of both batteries can generate excessive heat in the external charger, the various charging algorithms are designed to ensure that both batteries are ultimately charged, but in a manner considerate of heat generation. In some embodiments, the charging algorithms prevent simultaneous charging of both batteries by arbitrating which battery is given charging precedence at a given point in time. In other embodiments, the charging algorithms allow for simultaneous charging of both batteries, but with at least one of the batteries being only weakly charged at low power levels. In other embodiments, the temperature generated in the external charger is monitored and used to control the charging algorithm. In these embodiments, if a safe temperature is exceeded, then the charging algorithms change to new temperature-reducing schemes which still allow for both batteries to be ultimately charged.

Abstract: A method and apparatus for collecting ultrasonic test data from a railway wheel with an ultrasonic testing apparatus is described. The railway wheel is supported by two drive rollers, each having an indentation which engages with and rotates the wheel. An indexing transducer moves across the rotating wheel, collecting ultrasonic test data while a fixed transducer correlates a reference position on the wheel to the collected test data. To maintain the accuracy of the reference position to the collected test data, it is desirable to maintain the rotational stability of the wheel, minimizing any dynamic instability caused by dimensional tolerances in the wheel. To mitigate instabilities resulting from dimensional tolerances, the indentation of the drive rollers, which engage and drive the flange of the wheel, are variably spaced using a resilient member to maintain frictional contact between the wheel and the drive roller. This allows the indentation to accommodate the varying dimensional tolerances of the wheel flange, mitigating the possibility of dynamic instability resulting from departure of the wheel flange from the indentation.
