Job Monitoring System for Coiled Tubing Units

The Rapidlogger for coiled tubing is a compact, cost-effective data acquisition and job recording system for coiled tubing units. It records depth, speed, tubing weight, circulating pressure, wellhead pressure, pump rate and pump volume, shows them on a backlit display in the cab, and can stop the injector when the weight limits are exceeded. It is available in regular and hazardous-area configurations and needs no PC to run a job.
Who uses it
Coiled tubing contractors fitting new units or retrofitting older control cabs, nitrogen and fluid pumping crews working with CT units, and operators who want a complete depth and weight record of every run. The package is small enough to retrofit into an existing control cab, and the same unit can be switched to the cementing or slickline mode for other work.
What it measures
- Depth and speed from one or two quadrature encoders on the injector friction wheel. With two encoders the unit runs a fastest-wheel algorithm that ignores a slipping wheel and gives a more accurate depth. Depth can be zeroed or set to a tagged reference from the keypad.
- Tubing weight (hanging weight) from the injector load cell, with the lever ratio of the injector head entered once. Over-pull and snub limits can trip the unit's relay output.
- Circulating pressure and wellhead pressure from wing-union or flange-mounted transducers
- Pump rate and total volume from a stroke counter or flowmeter
- Spare analog and frequency inputs for fluid temperature, tank level or a second pump
The Rapidlogger weight calibrator verifies the injector load cell against a NIST-traceable reference on site.
How it works
The system is simple to use and an equipment operator can run it without training. Job data is recorded on removable MMC/SD flash memory cards and can be downloaded to a USB flash drive on the unit or over the network. The large internal memory holds dozens of jobs. The unit can be programmed to stop the CT unit if the hanging weight limits are exceeded, avoiding pipe parting incidents; Tech Note 68 describes the over-pull safety valve wiring. For hazardous areas the Rapidlogger ExD can be mounted at the injector as an explosion-proof remote device, reading the encoders and wellhead pressure and sending the data to the cab over CAN bus, MODBUS or armoured Ethernet.
Software
RapidVu is the software for graphing and preparing quick job reports on a PC. It is not required to run and record a job, but it can acquire data from the Rapidlogger in real time, play back a previously recorded job from a USB stick and output WITS data to the customer's system.
