TORNADO-27 permanent gauges and monitoring equipment have multiple levels of gauges and surface data acquisition systems to choose from, making these systems work for diverse applications from low pressure CBM wells to extremely corrosive wells with high concentration carbon dioxide [CO2] and/or hydrogen sulphide [H2S].
Customers can also choose from single to multi-drop permanent gauge completions with an option of gauge reading tubing pressure or annulus pressure. All of TORNADO’s state-of-the-art downhole tools incorporate industry leading sensors, innovative electronic components, and an electron beam welded housing design.
The link between the user and the downhole gauges is created by the Surface Data Acquisition Unit (SDAU). There are multiple configurations to choose from, including SmartWatcher Touch (for TORNADO27-PCP gauges) that provides instant data trending and charting to SmartWatcher II which makes it possible to connect up to four wells— with a maximum of four gauges per well—and therefore a total of 16 gauges communicating to the surface unit.
The SDAU can be powered by AC/DC power, or optional solar panel/battery power. TORNADO SmartWatcher software is used to configure the SDAU and download data to a computer via USB port. Customers can also connect to the SDAU using its Modbus (RS232/485 or fibre optic) interface.
TORNADO can also provide all the accessories necessary for intelligent well completions. This includes gauge carriers, downhole cable, cable protectors, cable head and wellhead outlets.
