A pressure and temperature gauge for Side Pocket Mandrel applications.
The ALS SPM Internal Gauge is a dual function Piezo Gauge assembly designed with seal stacks for plugging off an industry-standard 1.5" Side Pocket Mandrel. The gauge is fully automatic, capable of recording accurate real-time internal tubing pressure and temperature. With the SPM Internal Gauge located in place, full bore access is gained into the well. Unlike conventional Gauge Carriers, the SPM Internal Gauge can be recovered without pulling the completion.
The gauge is supplied in monitor mode and will record data at a pre-set sampling interval to memory when a user-programmed pressure or temperature threshold has been exceeded. The gauge reverts to monitor mode and stops recording data when the well pressure and temperature fall below both threshold values. Data is captured for the entire operation with no operator input required.
This low power gauge uses a single AA size battery which has no dangerous goods shipping restrictions. A built in real time clock ensures accurate data is stored with real time values and the data from each survey is stored individually in its large memory for easy download and analysis.
Our Windows-based Memory Gauge software is easy to operate, even for the beginner, and simple communication steps to download data from the gauge will provide a graphical plot display. For the more advanced user, features such as plot manipulation tools, data export options and Gradient Survey/Report generation tools, are available.
