  • Patent number: 7031840
    Abstract: A method to create a drilling performance assessment ratio. The ratio includes the steps of establishing a technical minimum time limit standard for each of multiple sequential steps required for a drilling operation. Actual time performance for each of the multiple steps is measured for an actual drilling operation.

  • Patent number: 7027929
    Abstract: Seismic traces of 3D surveys are interpolated using polynomials in 4D space from a less densely sampled real data set of source points S(x,y) and receiver points R(x,y). Input seismic traces should be pre-processed by normal move out (NMO) and static corrections. Input traces contributing to each single interpolated trace are chosen from a selected number of traces closest to each interpolated trace in 4D space. The methodology in accordance with the invention is designed to minimize computational load. The amplitude of an interpolated trace is modeled with a two-term Amplitude vs. Offset (AVO) formulation.

  • Patent number: 7027928
    Abstract: A method for determining a parameter of interest of a formation fluid, comprises moving a tool attached to a tubular member along a borehole in a subterranean formation. The tool is used to determine a formation fluid pressure and a formation fluid temperature at predetermined locations along the borehole and calculating a formation fluid density along the borehole therefrom. A density of a reference fluid is determined along the borehole and is related to the formation fluid pressure and the formation fluid temperature. The parameter of interest of the formation fluid is determined at a predetermined location from a comparison of the corresponding formation fluid density and the reference fluid density at the predetermined location.

  • Patent number: 7020558
    Abstract: A Method of measuring local similarities between seismic trace cubes (3D survey) obtained from a volume of an underground zone, corresponding to prestack data or to repeated seismic surveys (4D survey). For each point of the volume considered, the method comprises a) extracting, from each seismic trace cube, a volume neighborhood centered on a point, referred to as current point, and consisting of a set of seismic traces in limited number; b) applying an analysis technique referred to as (GPCA) allowing defining synthetic variables; and c) determining a coherence value from the synthetic extracted variables measuring the local similarity between the seismic trace cubes extracted from the volume neighborhood of the current point. The coherence value thus calculated is assigned to the current point. The coherence values of all of the current points form a coherence cube. An application is finer monitoring of the evolution with time of a reservoir under development.

  • Patent number: 7016784
    Abstract: A method of generating short-, medium-range and seasonal-timescale weather or climate forecasts by running an ensemble of computer models on a distributed computing system or network. Individual model integrations are interrogated to select those that most closely ressemble observed conditions in the present and recent past and the forecast based on a weighted average of future predictions based on this subset of the ensemble. The selection criteria determining which models are deemed to fit the observations most closely may be adjusted to optimize the use of observations in forecasting specific climate variables or geographic regions in order to develop forcasts tailored to particular applications.

  • Patent number: 7010429
    Abstract: A system and method of correcting skin effect of conductivity measurements made by electromagnetic induction well logging instruments. A limited number of measurements using different frequencies may be used. The skin effect correction system and method is capable of processing a complex signal waveform but only requires the in-phase signal measurements which are then corrected for the skin effect value and the geometric factors of the apparent conductivity measurements, thus making the corrected measurements suitable for advanced processing with modern array-type induction logging tools.

  • Patent number: 7006919
    Abstract: Methods and apparatus for continuous real-time measurement of bulk material using gamma irradiation and neutron irradiation. A DGA device monitors bulk material flow and produces a spectrum that is compared to a baseline spectrum to produce a relative weight/impurity ratio. A PGNAA device monitors the same bulk material flow and produces a spectrum that is compared to a library of spectrums to produce a relative component ratio. The relative component ratio is processed with the relative weight/impurity ratio to produce an absolute weight and impurity value, which is then processed with the relative component ratio to produce absolute component, or analyte, values.

  • Patent number: 7006920
    Abstract: The present invention is directed to incrementing a well service rig in such a manner that activity-based and/or time-based data for the well site is recorded. The acquired data can be transmitted via wired, wireless, satellite or physical to a data center preferably controlled by the work-over rig owner, but alternately controlled by the well owner or another. The data can thereafter be used to provide the customer a detailed invoice or a searchable, secure web-based database. With such information, the customer can schedule other services at the well site. Further, the customer will have access to detailed data on the actual service performed. The present invention fosters a synergistic relationship among the customer and the service companies that promotes a safe environment by monitoring crew work activities and equipment speeds; improving productivity; reducing operation expenses through improved job processes; and better data management and reduced operational failures.
