Abstract: An injection tip assembly 10 and methods for use more reliably provide for delivery of fluid substances, such as materials that promote removal, destruction, or isolation of contaminants, into targeted zones within soil or bedrock. The injection tip assembly 10 permits the application of pressurized fluid 163 so as to erode or cut a desired cavity or eroded volume 164 within the subsurface 14, allows for timely observation, adjustment, and control of pressure within the cavity, and directs the delivery of a second substance or fluid that may incorporate desired materials. The consequence of managed erosion and pressure control is to nucleate and propagate a hydraulic fracture of desirable form that optimally delivers remedial agents throughout the targeted formation.

Abstract: The present application discloses a technique for targeting therapeutic thermal energy to human tissue that is subject to displacement during a respiratory cycle using ARMA modeling. It discloses using an ARMA treatment of MRI tracking data of salient features of the tissue of interest to predict the spacial position of the portion of the tissue to be treated and using this prediction to guide the application of the thermal energy. It also discloses that this technique is particularly useful when the tissue of interest undergoes elastic deformation in a respiratory cycle and high energy focused ultrasound (HIFU) is used to ablate diseased tissue such as a cancerous tumor.

Abstract: A method of image reconstruction comprising: obtaining a Helmholtz reciprocal pair of images of an object, the images comprising a first image and a corresponding reciprocal image; determining an imaging geometry associated with the obtaining; selecting a plurality of points in the first image and identifying corresponding candidate points in the corresponding reciprocal image; matching a selected point of the plurality of points and a candidate point of the corresponding candidate points. A method of image registration with an object comprising: obtaining a Helmholtz reciprocal pair of images of an object, the Helmholtz reciprocal pair of images comprising a first image and a corresponding reciprocal image; estimating a pose for the object; predicting an estimated image corresponding to the pose and one image of the reciprocal pair of images; comparing the estimated image with a corresponding actual image from the pair of images; and refining the estimating a pose based on the comparing.

Abstract: Electrical generating apparatus is provided which connects to the production tubing. In a preferred embodiment, this apparatus includes a housing having a primary flow passageway in communication with the production tubing. The housing also includes a laterally displaced side passageway communicating with the primary flow passageway such that production fluid passes upwardly towards the surface through the primary and side passageways. A flow diverter may be positioned in the housing to divert a variable amount of production fluid from the production tubing and into the side passageway. In accordance with an important feature of this invention, an electrical generator is located at least partially in or along the side passageway. The electrical generator generates electricity through the interaction of the flowing production fluid.

Abstract: A downhole multilateral completion tool is disclosed which includes a premachined window joint and a production tube adapted to be moved downhole through the window joint and kicked off into the pre-drilled lateral. A flange and seal form a part of the uphole end of the production tube and provide a 3500 psi seal after the production tube is placed in the lateral. The invention, moreover, includes an energizing sleeve which biases the flange into a sealed position and a packer which by pulling the production tube, enhances the seal of the flange.
