    • Logging systems and methods to provide azimuthally-sensitive saturation logs. In some embodiments a processor operates on formation porosity and resistivity measurements from an azimuthally-sensitive logging tool assembly to derive a saturation log having a dependence on tool position and rotation angle, and possibly on radial distance as well. The processor may provide the log to a user via a screen, printer, or some other display mechanism. The logging tool assembly includes at least one tool to measure formation porosity. Suitable tools include a gamma density tool, a neutron density tool, a nuclear magnetic resonance tool, and an acoustic tool. The tool assembly further includes at least one tool to measure formation resistivity. Suitable tools include a laterolog tool, an induction tool, and a propagation resistivity tool. The tool assembly can be a wireline sonde, a tubing-conveyed logging assembly, or a logging while drilling tool assembly.
    • 记录系统和方法以提供方位角敏感的饱和日志。 在一些实施例中,处理器对来自方位敏感测井工具组件的地层孔隙度和电阻率测量结果进行操作,以导出与工具位置和旋转角度有关的饱和度测井值,以及可能的径向距离。 处理器可以经由屏幕,打印机或某些其他显示机构向用户提供日志。 测井工具组件包括至少一个测量地层孔隙度的工具。 合适的工具包括伽马密度工具,中子密度工具,核磁共振工具和声学工具。 工具组件还包括至少一个测量地层电阻率的工具。 合适的工具包括后工具,感应工具和传播电阻率工具。 工具组件可以是有线探头,管道输送测井组件或钻井工具组件中的测井。
