Downhole Gauges
Litewell's permanent Sapphire and Quartz pressure gauges use proprietary technology to record pressure and temperature data downhole, before transmitting this data to the surface via a high speed telemetry link. We currently offer a range of pressure/temperature sensors to suit all well specifications and budgets.
Our range of permanent gauges have a fully welded corrosive-resistant alloy design based on material selection, as well as a redundant pressure testable metal-to-metal cable head. This makes them ideal for providing long-term data quality and reliability.
Using digital data transmission and subsurface signal processing they eliminate the effects of noise from signal transmission, maximizing accuracy and stability of measurement.
Multi-drop Permanent Downhole Monitoring
Litewell’s multi-drop permanent downhole monitoring system provides the ability to install multiple sensors on a single Tubing Encapsulated Conductor Cable (TEC cable). This provides a cost-effective solution when multiple sensors are required. Each gauge configuration is connected to the wellhead electrical outlet through a monoconductor tube wire strapped to the tubing, thus allowing real-time continuous readout of the reservoir parameters without production shut-in, under dynamic well conditions
This downhole network supports bi-directional communication, delivers the ability to remove a sensor or gauge from the line, and enables monitoring of multiple zones. This assists with redundancy and integration, without the cost and risk associated with running multiple lines.
