  • Patent number: 7539577
    Abstract: A method of data acquisition during survey of buried linear conductors. A first step involves passing a dynamic data stream of data from survey instruments through a filtering software adapted to reduce the volume of data being processed. A second step involves setting a survey interval within the software, the survey interval being a selected distance between survey points in order to provide a desired survey point density. A third step involves setting a geographic activation buffer within the software in relation to the survey interval. The filtering software is programmed to process data within the activation buffer separately from the dynamic data stream.

  • Patent number: 7424365
    Abstract: A data compression technique for MWD applications uses feature detection, extraction, followed by image compression for only the region(s) of interest. The detection approach processes data in real time. It triggers on the start and end of a feature without processing any further features. This provides feature detection with zero latency. Compressing only the region of interest provides data compression with both higher resolution and higher compression ratio.

  • Patent number: 7421346
    Abstract: A method of matching the impulse response of a hydrophone and the impulse of a geophone accelerometer comprises performing a calculus operation upon the response of one of the hydrophone and the accelerometer. A filter is then derived from the output of the calculus operation and the response of the other of the hydrophone and the accelerometer. The filter may then be used to match seismic data acquired by the one of the hydrophone and the accelerometer to seismic data acquired by the other of the hydrophone and the accelerometer. The calculus operation may comprise differentiating the hydrophone response, or integrating the accelerometer impulse response.

  • Patent number: 7398159
    Abstract: Methods and systems are provided for downhole analysis of formation fluids by deriving differential fluid properties and associated uncertainty in the predicted fluid properties based on downhole data less sensitive to systematic errors in measurements, and generating answer products of interest based on the differences in the fluid properties. Measured data are used to compute levels of contamination in downhole fluids using, for example, an oil-base mud contamination monitoring (OCM) algorithm. Fluid properties are predicted for the fluids and uncertainties in predicted fluid properties are derived. A statistical framework is provided for comparing the fluids to generate robust, real-time answer products relating to the formation fluids and reservoirs thereof. Systematic errors in measured data are reduced or eliminated by preferred sampling procedures.

  • Patent number: 7392136
    Abstract: The invention allows construction of the architecture of sedimentary layers deposited on a topographic surface as a result of the passage of sedimentary currents, using cellular automata. The topographic surface is discretized into a set of cellular automata. Then, for each current and each automaton, a stationary physical state resulting from an iterative process wherein intermediate physical states are constructed by material and energy exchanges between the automata is determined. These automata are thus constructed so as to be representative of the action of the sedimentary currents on the construction of the sedimentary architecture. A set of geologic variables allowing the architecture of the sedimentary layers to be reconstructed is thus deduced from these stationary physical states. Preferred fields of application of the method are oil exploration and production and reservoir characterization.

  • Patent number: 7389185
    Abstract: Methods and systems are provided for evaluating subsurface earth oil and gas formations. More particularly, methods and systems are provided for determining reservoir properties such as reservoir transmissibilities and average reservoir pressures of formation layer(s) using quantitative refracture-candidate diagnostic methods. The methods herein may use pressure falloff data from the introduction of an injection fluid at a pressure above the formation fracture pressure to analyze reservoir properties. The model recognizes that a new induced fracture creates additional storage volume in the formation and that a quantitative refracture-candidate diagnostic test in a layer may exhibit variable storage during the pressure falloff, and a change in storage may be observed at hydraulic fracture closure.

  • Patent number: 7379817
    Abstract: Methods and articles of manufacture for providing an indication or representation that describes the state of weather over a period in the past for a particular location. Observation data for the location is accumulated and stored over the period. Because forecast engines exist and can be adapted for use in determining the indication of weather, the observation data is converted into a format of forecast data. The data is then grouped into subsets and processed as forecast data. For each subset, a representation of weather is determined. The representations of weather for each subset are then processed to determine the representation of weather for the period of time.

  • Patent number: 7376515
    Abstract: There is provided herein a system and method of collecting, EM data in the context(s) of hydrocarbon exploration, appraisal, development, and surveillance, which provides improved ground coupling between the electrodes and the earth or surface ice and, as a consequence, a higher quality transmitted and received signal is obtained thereby. Where the surface of the ground is saturated and frozen (e.g., in the case of a survey conducted on sea ice or frozen tundra), the survey instruments (sources and receivers) may be coupled more faithfully to the surface by drilling or melting holes into the ice (or frozen tundra) and inserting electrodes into the resulting holes. Each hole may (or may not) be lined with material to retard the loss of water therefrom. Preferably, each of the holes (source and receiver) will be filled with water (fresh or salt) before data collection begins.

  • Patent number: 7376517
    Abstract: The present invention includes a method for determining interval values of seismic quality factor, Q, from seismic data. Seismic data is recorded and preprocessed as necessary. Estimates of amplitude spectra are determined from the seismic data. Logarithms are taken of the amplitude spectra and weights derived from the amplitude spectra. Interval values of seismic quality factor, Q, are determined by performing a weighted fit to the log-amplitude spectra with a function that is parameterized by an initial wavelet, an attenuation profile (1/Q) and an absolute-scaling profile.
