摘要： A pulsed neutron source irradiates an earth formation. The irradiation produces N16 from O16 in a fluid in the borehole, and the gamma rays produced by the subsequent decay of N16 are detected by a plurality of spaced apart detectors. The count rates of the detectors are accumulated over a time sampling interval to produce temporal signals. Processing of the temporal signals using correlation, differentiation and/or semblance techniques is used for determination of the flow velocity of one or more fluids in the borehole.

摘要： Data from a string of multiple formation evaluation data sensor are evaluated by an expert system. Based on the analysis, the logging speed is increased if all the sensors justify it, and is reduced if any of the sensors require a reduced logging speed. Alternatively, the sensitive volume of a NMR sensor is altered based on a determination of a fraction of the sensitive volume that includes a borehole fluid.

摘要： This disclosure provides a method for measuring the velocities of water volumes flowing co-directionally in separate conduits nested such as in injection or production well-bores. The method allows an oxygen activation measurement of the velocity of the water flow in the tubing-casing annulus in the presence of water flowing in the tubing string in the same direction. The method allows continuous logging at variable or constant cable velocities or stationary logging. Based on the method of velocity gauging, the method isolates the signal from the annular flow and can produce a continuous log of linear and volumetric annular flow rates with depth.

摘要： A method, apparatus, and machine-readable medium for evaluating an earth formation having a fluid mixture including oil and water therein. The earth formation is irradiated with a source and radiation resulting from interaction of the radiation with nuclei is measured at at least two detectors. A fluid zone parameter (FZP) indicative of oil saturation is determined and values of the FZP are established for at least two different values of oil saturation. A value of the oil saturation is estimated using the determined value of the FZP and established values of the FZP. The process may be repeated at a plurality of depths and the determined value of the FZP is displayed at the plurality of depths.
