Abstract: Structure for deep MWD resistivity measurements suitable for both geo-steering and measurements ahead of the drill bit is disclosed. Alternating current is transmitted through a loop and an induction signal is measured by a two-coil bucking receiving system placed at some distance from the transmitter. To further reduce a parasitic effect of the currents in the pipe, a conductive copper shield wrapping around the pipe is used. The length of the shield is about one and one-half to two times longer than the longest transmitter/receiver spacing of the structure. The transmitter/receiver system is located in the center of the described electromagnetic shield.

In at least one example of the invention, a method of retrieval of material (e.g., a tubing string) having broken control or monitoring lines from a cased well is provided. The method comprises: isolating, from the well casing, broken lines above the material to be retrieved, thereby creating a substantially axial work passage; grasping the material to be removed through the substantially axial work passage; and pulling the material to be retrieved and the restrained lines from the well. Example shrouds, probes and other members are also described.

Abstract: A source roll having a first layer of liner paper and a second roll of two-sided adhesive is fed through a pair of rollers having six aligned rotary die cutters sized to cut through only the adhesive layer. The excess adhesive web is peeling off and removed from the process. The liner paper with spaced apart sets of six aligned adhesive dots is then laminated with a clear plastic having two sides, one uncoated and one coated, to allow the clear plastic to be easily rolled up and then unrolled, and the liner paper is peeled off and removed from the process. The material remaining having the adhesive circular dots is cut into six long strips each having six adhesive dots which can be used to display small discrete packages.

Abstract: A method, system, and apparatus are provided for focused ultrasonic acoustic imaging of objects within a body of water. Echo soundings are collected, produced by an ultrasonic transmitter and detected by an ultrasonic receiver. Spatial location information of the transmitter and receiver is collected and associated with each echo sounding. A focused signal spatial location is selected at a desired output location. One or more of the collected soundings are selected. An echo signal from each selected sounding is selected. The signal selection is determined by a calculation of which signal from the selected sounding scattered from an object at the selected focused signal spatial location. A focused echo signal is formed by combining the selected signals for the selected focused signal location. The focused signals are graphed, based on their respective selected focused signal spatial locations, producing a focused image.

In at least one example, the desired property is gas oil ratio. In another example, the desired property is gas brine ratio.

In at least one example, the system comprises a means for receiving a set of records, and the set of records includes at least one representing a treatment prescribed by the first care-giver, and at least one representing at least one patient characteristic. There is also a means for determining, from the set of records, independently of records relating to effectiveness of the treatment prescribed for the patient, and based on a predetermined set of screening criteria, whether a different treatment is appropriate. Further, a means is provided for generating, based on the screening, an eligibility tag associated with the patient for providing notice to the patient associated with the eligibility tag of the different treatment availability at no cost to the patient and of a financial consequence of receipt of the treatment.

Abstract: A method and system for measuring formation resisitivity is achieved by introducing one or more continuous phase modulated electrical signals into the formation, each signal introduced at a different location. The current of each introduced electrical signal is then sensed, producing an analog voltage signal as a measurement of the formation. Each introduced electrical signal is compared with its respective measured signal of the formation. Each comparison is made in a quadrature demodulation device, producing an in-phase demodulated signal. A quasi-direct-current signal is extracted from each in-phase demodulated signal, producing an analog measurement related to the resistivity of the formation. Each analog measurement is converted into a digital value for further processing. Successive measurements are digitally summed and averaged to increase the signal to noise ratio.

Abstract: A casing running tool comprising an integral elevation module and make-up/torque module. In accordance with one aspect or the invention, the tool is adapted to automatically engage a collared end of a tubular structure such as a casing string segment. The integral make-up/torque module is actuated by hydraulic control lines to exert compression force upon the outer diameter of a tubular, such as a casing string segment. This compression force is sufficient to enable torque to be applied to the tubular without slippage. In one embodiment, the make-up/torque module comprises an outer body carrying a plurality of hydraulically-actuable pistons, such that the tool is actuable from the rig floor to grasp the tubular with sufficient force that rotational force (torque) supplied via a drive motor in a top-drive rig. In accordance with another embodiment, the multifunction tool further includes an internal ball valve assembly for selectively allowing or restricting fluid flow through the tool.

The drill string includes a flow control device to block flow in the drill string passage or in the annulus formed between the drill string and the wellbore inner wall from lowing into the bit when flow is reduced or stopped. The flow can take place due to fluid density differences resulting from impactors being in suspension in the fluid. The flow control device includes a selectively openable and closable valve. Valve embodiments include valves having flapper elements, a plurality of cables suspended in an annular configuration, and whisker elements.

Abstract: The present invention provides a method of installing an environmental control system so as to allow for separate sizing of treatment and bypass capacity while also offering the ability to make or change either treatment or bypass capacities at different times. This is accomplished by containing the treatment and bypass functions in separate chambers, using screen, baffle, or coalescing media pack to further refine effectiveness and capacity of each structure independently. The control structure and interceptor structure may be pre-engineered to a variety of sizes, capacities, or other specifications. This allows simple selection of a specific control structure and a specific interceptor structure from a variety of combinations, eliminating the need for custom engineering for each installation.

Abstract: An oral medicine dispenser for administering liquid medicine to a child includes: a cup having a cap and nozzle with a medicine compartment located therein. When a child sucks the nozzle, the medicine flows from the medicine container into the nozzle. The nozzle has two separate chambers. One chamber of the nozzle delivers the medicine from the medicine compartment to the back of the child's mouth. The other chamber delivers a fluid such as juice from the cup to the front of the child's mouth so as to taste more appealing to the child.
