Fluid-Capacitance Tool


Provides qualitative fluid identification data


Applications

  • Fluid identification
  • Fluid holdup


Features and Benefits

  • Combinable with all high-speed digital (HD) telemetry tools for comprehensive evaluation
  • Compact, versatile, and robust


Tool Description

The Weatherford fluid-capacitance tool provides an indication of fluid type surrounding the sensor by measuring the dielectric constant of the fluid between the sensor and tool body. Used in combination with other sensors, it provides qualitative fluid identification data.

The oscillator electronics are on the sensor circuit board and not in the sensor section, reducing complexity and simplifying maintenance.

The fluid-capacitance tool provides useful qualitative analysis in high gas/oil ratio (GOR) wells.
