    摘要： A microfluidic system for performing fluid analysis is described having: (a) a submersible housing having a fluid analysis means and a power supply to provide power to said system; and (b) a substrate for receiving a fluid sample, having embedded therein a fluid sample inlet, a reagent inlet, a fluid sample outlet, and a mixing region in fluid communication with the fluid sample inlet, the reagent inlet, and the fluid sample outlet, and wherein the substrate includes a fluid drive means for moving the fluid sample through the substrate, and wherein the substrate interconnects with the housing. At least a portion of the fluid analysis means may be embedded in the substrate.

    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： 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.

    摘要： Methods of assuring that a representative formation and/or fluid sample of a subterranean reservoir is obtained are provided. One method of validating a reservoir fluid sample obtained from a wellbore includes the steps of acquiring a reservoir fluid sample in the wellbore; measuring a property of the fluid sample downhole with a technique to obtain a measured downhole fluid property; replicating the measuring technique used to obtain the measured downhole fluid property to obtain at a remote location from the wellbore with a technique to obtain at least one measured remote location fluid property; validating the fluid sample through comparison of the measured downhole fluid property and the at least one measured remote location fluid property.
