摘要： Advanced remote self-contained chromatographic systems and techniques for analyzing a mixture comprising components having a wide range of boiling points. The chromatographic systems and techniques can utilize components and techniques that allow staged, simultaneous, and/or sequential vaporization of an analyte to facilitate rapid analysis. The chromatographic systems and techniques can also utilize components and techniques that focus eluents from a first separation stage prior to reduce characterization time in subsequent stages.

摘要： The operation, analysis and interpretation of a chromatographic system can be significantly enhanced by coupling therewith one or more fluid property measurements that provides an initial indication of the fluid type, the presence of any contamination, an estimate of the hydrocarbon composition (C1, C2-C5 and C6+), gas/oil ratio, color and/or fluorescence measurements. Other measurements that can be used in the initial stage can include density, viscosity, phase transition determinations. These measurements may be used to enhance, in real-time, the GC sampling protocol, the analysis protocol and also improve the robustness of the interpretation of the chromatogram.

摘要： In accordance with an embodiment of the present invention, a method of processing large volumes of data to allow for real-time reservoir management is disclosed, comprising: a) acquiring a first data series from a first reservoir sensor; b) establishing a set of criteria based on reservoir management objectives, sensor characteristics, sensor location, nature of the reservoir, and data storage optimization, etc.; c) identifying one or more subsets of the first data series meeting at least one of the criteria; and optionally d) generating one or more second data series based on at least one of the subsets. This methodology may be repeated for numerous reservoir sensors. This methodology allows for intelligent evaluation of sensor data by using carefully established criteria to intelligently select one or more subsets of data. In an alternative embodiment, sensor data from one or more sensors may be evaluated while processing data from a different sensor.

摘要： Earth formations are characterized by using an array of electrodes which can measure streaming potentials in the formation, and by interpreting the data obtained by the electrodes. The electrodes are placed on a wireline tool, a LWD tool, or in a fixed manner about a completed wellbore. The measured streaming potentials are generated by drilling with an overbearing pressure, slitting the mudcake in a borehole, acid injection, or any of various other manners which causes fluid movement. The data obtained is interpreted to locate fractures, measure formation permeability, estimate formation pressure, monitor drilling fluid loss, detect abnormal pressure, etc. Particularly, a streaming potential voltage transient having a double peak profile signifies the presence of a formation fracture.

摘要： It is shown that a pressure pulse originating in a well is correlated to a pulse observed at a distant well with a characteristic time. The correlation time is directly related to the diffusion time scale arising out of the pressure diffusion equation. The relationship is affected by the source-observer or observer-observer distance but the correction is small for large distances. In practice, further corrections have to be included for finite width pulses. For these pulses, a practical scheme for continuous permeability monitoring is presented.
