Abstract: A region of a borehole with one or more openings to be sealed off, such as one or more fractures, voids, and or pores, may or may not be sealed off around a tubular string with a borehole seal such as a packer or plug. A carrying fluid may be utilized to transport a filtration material into the opening to create a bridge, which at least partially seals the opening, but still provides a flow path that permits fluid flow therethrough. A solid material and/or settable material may then utilize the fluid flow subsequently or be simultaneously spotted with or behind the filtration material to thereby form compositions which effectively seals off the flow path into the one or more openings.

In one embodiment, the road grader weighs ten to twenty tons, has articulating tandem rear wheels, front steering wheels, and hydraulic vertical and horizontal angle blade adjusters, whereby the disc tillers may be oriented in a manner for tilling at a desired depth and orientation, and the road grader features can be adjusted to counteract forces produced by the gang of discs. Mud scrapers are preferably provided for individual discs on an opposite side of the gang of discs with respect to the grader blade. In one embodiment, a hitch mechanism with stop surfaces is provided behind the grader blade for mounting and/or removal of the gang of discs to the grader blade within minutes without need of special tools.

Abstract: The present invention discloses apparatus and methods for a lightweight subsea intervention package that may be installed using vessels with a smaller lifting capacity than semi-submersible platforms so that the subsea intervention package can be transported, installed, and removed from a subsea well in less time and with less cost. In one embodiment, the present invention comprises a lower riser package for controlling the subsea well which utilizes two hydraulically activated gate valves. An emergency disconnect package is secured to the lower riser package utilizing a disconnect mechanism. The emergency disconnect package is operable to seal the bottom of a riser if the disconnect mechanism is activated to thereby minimize environmental leakage of fluid from the riser.

Abstract: A temporary or portable traffic signal can be utilized to regulate traffic during power outages. However, when power is restored and the normal operation of the permanently installed traffic signal resumes, then a method of interconnecting the permanent and temporary systems ensures that the operation of the two system are synchronized in predetermined and/or selectable modes of operation. Whenever power is available, an interface detects operation of the permanently installed main system and produces signals that can be used in one mode of operation to direct the portable system to ignore its internal timing sequences and synchronize with the main system, or in another mode of operation to cease its operation.

Abstract: A digital motor control system utilizes time duration electric pulses generated by digital logic to control the motor speed and direction of rotation of a D.C. or A.C. motor. The digital logic produces width modulated pulses that can be connected to large or small electric motors by mechanical or electrical relays or switches to provide efficient motor control with little control circuit power loss. The mechanical or electrical switches are responsive to the digital logic to change motor direction or remove power from the motor windings. A variable control element such as a computer joystick can be utilized to control both direction and speed of the motor. The system can be configured as an open loop system or as a closed loop servo with a feed back element to control the rotational position of the motor.

Abstract: Autonomous non-destructive inspection equipment provides automatic and/or continuous inspection and evaluation of a material under inspection. The inspection equipment preferably comprises at least one detection sensor and at least one detection sensor interface for a computer. The autonomous non-destructive inspection system may also be retrofitted into conventional inspection systems by extracting pertinent features through spectral frequency analysis and sensor compensation and utilizing those features in the autonomous non-destructive inspection system.

Abstract: A pulse production interval measurement module (or temporal reconciliation module) for preferred use with a computational flowmeter and/or non-computational flowmeters to thereby temporally reconcile or time shift flowmeter output produced by a volume of fluid flow through the computational flowmeter with the start and stop times of the flow of a calibrated fluid volume through a prover. The pulse production interval measurement module may be implemented with software and/or hardware and operate on stored data or real time or near real time measurements.

Abstract: The present invention provides drilling assembles and methods that are especially useful for a bottom hole drilling assembly for drilling/reaming/or other operations related to drilling a borehole through an earth formation. In one embodiment, the drilling assembly utilizes standard drill collars which are modified to accept force transfer sections. In another embodiment, the drilling assembly comprises a tension inducing sub which creates a force that may be used to place the bottom hole assembly or portions thereof in tension. In another embodiment, a reaming assembly is held in tension to provide a stiffer reaming assembly.

Abstract: A method of seismic analysis is disclosed for extracting information relating to lithology, porosity, fluids, and AVO types and/or displaying the extracted information. In one possible embodiment, AVO points are plotted and a distance and/or angle is utilized for extracting this information. Various portrayals of the extracted information displays may be produced including displays wherein the extracted information is then displayed in terms of colors for respective x, y, z locations. The AVO points may or may not be normalized based on a shape of a cluster of the AVO points prior to extraction of the information.

Abstract: A more computationally efficient and scalable systolic architecture is provided for computing the discrete Fourier transform. The systolic architecture also provides a method for reducing the array area by limiting the number of complex multipliers.

The resulting design provides an array comprised of a plurality of smaller base-4 matrices that can simply be added or removed to provide scalability of the design for applications involving different transform lengths to be calculated. In this embodiment, the systolic array size provides greater flexibility because it can be applied for use with any transform length which is an integer multiple of sixteen.
