Applications

Rapidlogger is a self contained, state-of-the-art system for job monitoring and recording on slickline, wireline, (cementing, fracturing, mud, & nitrogen) pumping, coiled tubing rigs and wellhead monitoring. The Rapidlogger can record, monitor, display and report depth, speed, weight, wellhead pressure, pump-strokes, pump-totals, flow rates and other rig parameters.

Highlights

The Rapidlogger is oilfield rugged, compact, and cost-effective.  It is the most efficient system available in the market today.  The system is simple to use and an equipment operator can use the system without any training.  Job data can be recorded on removable and upgradeable MMC/SD flash memory cards.

The standard system has four analog data channels, 2 frequency channels, two encoder channel (for depth measurement).  The system is expandable and more data acquisition channels can be added as required.  The system runs on 12 to 24 Volts DC power (which is available on most oilfield units).  In the basic configuration the system can record more than 200 hours of job data.  This job memory can easily be increased with a higher capacity flash card.

The Rapidlogger is a stand-alone unit that does not require a PC for operation, display or recording of data.  However it can transmit its data to a PC if needed both in real-time and after the job to transfer data etc.

Features

The package is very compact and suitable for panel mounting in the control cab of oilfield trucks.  Rapidlogger has been specifically designed from the ground up for use in harsh and hazardous environment.  The maintenance free NEMA 4 enclosure houses the embedded computer, acquisition hardware, display, keypad and the flash memory.

A powerful PC application that runs on any Windows based PC is used to download the data in realtime or after the job to prepare a job report for the customer.

Slickline Mode:  When used in the slickline mode, the system measures, displays and records:  depth, line tension, wellhead pressure, and other parameters that the operator may choose.  The system can also correct the depth for line stretch and thermal expansion.  It can also shutdown the slickline winch with a solenoid valve based on a line over-pull condition.

Production Monitoring Mode:  When used in the production monitoring mode the system measures, displays and records: wellhead pressure, production flowrate, pumpjack speed, storage tank level and temperature. If needed it can also control the pump jack motor speed. Additional parameters can be selected, monitored and recorded. The unit can be networked on an Ethernet network for centralized monitoring and control.

Coiled Tubing Mode:  When used in the coiled tubing mode, the system measures, displays and records:  depth, speed, weight, wellhead pressure, circulating pressure, pump rate and other parameters that the operator may choose.  It can also trigger a solenoid valve to stop the unit if hanging weight or depth limits are exceeded.

Pump truck Mode:   When used in the pump truck mode, on a cementing, fracturing, Nitrogen or acid pump, the system measures, displays and records:  pump pressure, pump rate, pump volume, inlet pressure and other parameters that the operator may choose.  It can also trip the pump if the pressure exceeds a high limit preset by the operator.

Hardware

The basic Rapidlogger system is capable of acquiring four analog, two depth and two frequency channels.  It can also control one PWM high current digital output channel.  Additional channel inputs can be added to the base system as options.  The system operates from 12-24VDC or 110-240VAC.  The system can be retrofitted in existing units or incorporated into new service units.  The system has been designed for continuous operation in harsh environments. The unit can be custom configured for difficult or nonstandard applications.  Contact us with your specific requirements. 

 

Software    

The Rapidlogger software panel runs a real-time embedded operating system on its rugged high-speed microprocessor.  The real-time operating system allows the system to turn on instantly and be crash proof. 

The Rapidlogger-PC is the optional laptop software for generating job reports and downloading data to the PC runs under Windows (95/98/NT/2000).  The laptop and the PC software is not needed for operation or job recording.  It is only required for generating job reports or setting up enhanced data displays from the Rapidlogger system.

Rapidlogger is also available for Windows CE based pocket PCs.  This version can communicate with the Rapidlogger hardware over an optional WiFi interface and provide data anywhere on the wellsite within WiFi range.
