  • Patent number: 5343440
    Abstract: Seismic data is combined with well log data to generate a two-dimensional geopressure prediction display; this permits deviated and horizontal well planning plus lithology detection. Shale fraction analysis, compaction trend, and seismic velocity may be automatically or interactively generated on a computer work station with graphics displays to avoid anomalous results. Corrections to velocity predictions by check shots or VSP, and translation of trend curves for laterally offset areas increases accuracy of the geopressure predictions. Multiple wells' logs in a basin permits analysis fluid migrations.

  • Patent number: 5296711
    Abstract: A method and apparatus for remote detection of an oil slick at or near the surface of the water using a combination of two or more ultraviolet lasers and comparing the relative magnitude of the received Raman backscattering signal magnitudes to determine the existence of the oil slick. The use of two different laser frequencies provides for elimination of atmospheric transmission variations and wave modulation.

  • Patent number: 5224105
    Abstract: A system is provided for communicating high bandwidth data from a remotely operated semi-submersible vehicle to a mothership surface vessel. The data transmitted from the remotely operated vehicle is blocked and coded to improve the accuracy of the transmission. The remotely operated vehicle contains a large buffer for temporarily storing hydrophone data until it has been transmitted and acknowledged by the mothership. Each transmitted block is acknowledged by the mothership when it has been correctly received. Incorrect or missing acknowledgment signals indicate that some type of interference or outage has occurred in the communications channel. In such an event, the remotely operated vehicle can continually resend the recently transmitted data until receipt of correct acknowledgment signals indicates that the communications channel has been restored.

  • Patent number: 5204673
    Abstract: A method and an apparatus for recording the depth of a well logging apparatus is provided. The method and apparatus include the direct acquisition of broad depth information from the logging system conversion of the broad depth information to an acceptable digital signal and recording that signal on the audio track of a video cassette recorder. A microcontroller is used to convert broad depth information from either the logging system or the video cassette recorder (in the playback mode) to actual depth and depth rate for use by other displays and plotters.

  • Patent number: 5166910
    Abstract: A portable device for accurately measuring acoustic velocities in solids. This portable hand-held device (100) uses dual receiving transducer tips (110, 112) to allow differential measurement of acoustic velocity in a solid. A body having a handle uses a transmitting transducer tip (108) to transmit acoustic energy to a solid. The first receiving transducer tip (110) is used in conjunction with a second receiving transducer tip (112) mounted on the body a fixed distance from the first (110). The device (100) uses the differences in the time of arrival of the wavefront at the first and second transducers to calculate the acoustic velocity in a given solid. This differential measurement method reduces acoustic velocity measurement inaccuracies.

  • Patent number: 4891499
    Abstract: A silicon semiconductor wafer (26) is placed in a vacuum chamber (12) device side (28) facedown. Laser beams of equal power are directed at an edge point (72) and a center point (74) of the wafer (26). The laser beams are reflected from the edge point (72) and the center point (74) into first and second infrared photo-detectors (40-42). A differential amplifier (44) evaluates the reflected laser beams for a power difference and signals a current source (82). Current source (82) heats a quartz ring (46) which surrounds the wafer (26). The quartz ring (46) passes the heat to the wafer (26) until the amplifier (44) no longer senses a power difference, which is indicative of an equal wafer surface temperature.

  • Patent number: H1273
    Abstract: A method for training technicians to diagnose certain induced electronic faults using an internal combustion on a test stand engine capable of having faults inserted into electronic circuits. The faults are inserted into the engine by the instructor using switches concealed from the trainee. While the engine is operating the trainee, using diagnostic equipment, the trainee attempts to locate the electrical fault using a combination of observing symptoms and signal tracing.
