Description
Water Holdup Tool (Capacitance Tool)
The Water Holdup Tool (WHT) is an advanced downhole sensor designed for measuring the percentage of water holdup during Production Logging Operations. The tool operates by utilizing a cylindrical capacitor, in which the incoming fluid (a mixture of water, hydrocarbon, and gas) serves as the dielectric material. By determining the dielectric constant of the fluid, the WHT can accurately calculate the water holdup percentage.
The WHT is a versatile tool that can be integrated as part of the ENG+RD Production Logging Tool. For faster and more efficient data transmission, the WHT can be connected to the Fast Hybrid Telemetry Tool (FHT). Additionally, the tool features a memory mode, which allows for offline data analysis and interpretation.
