WellWatcher Quartz Extend

AC- or DC-powered high-resolution dual-sensor PT gauge

Simplify multizone monitoring and reduce wellhead and packer penetrations

The WellWatcher Quartz Extend AC- or DC-powered high-resolution dual-sensor PT gauge provides continuous, repeatable, and reliable pressure and temperature data as well as—using the ΔP method—downhole flow rate measurements. This makes it possible to characterize production and reservoir behavior in real time. In addition, it can be used to optimize flow control valve positions to maximize productivity or injection throughout the life of a well.

Monitor one zone or many, with power and telemetry in a single permanent cable

For completions that do require multizone monitoring, WellWatcher Quartz Extend gauges can be installed in each of the zones. Power and telemetry are provided by a single permanent cable. This configuration optimizes the completion architecture by simplifying installation and decreasing the number of wellhead and packer penetrations.
