1    Introduction

The Rapidlogger is a rugged and compact job monitoring system for the oilfield.  The unit is specially designed for use in the rough oilfield environment.  The unit powers the sensors, displays their data, run calculations, and records job information. In addition, the sensor data can be transmitted to a PC in real-time or after the completion of the job.  The Rapidlogger panel has been designed to be installed and used in harsh environments.  The unit will operate well in direct sunlight, rain, and salt water spray, however protecting it from the elements will extend its life and maintain its appearance.  The display on the unit is suitable for viewing in the direct sunlight and is equipped with a backlight for night time use.


The Rapidlogger is a rugged and compact job monitoring system for the oilfield.

The unit records data to the internal SD memory card any time it is powered on.  The user does not have to take any action to start job recording.  The job recording capacity varies based on the number of parameters being recorded and the size of the memory card installed.  But for reference, if eight parameters are being recorded at a one second interval to a 1 GB memory card then the unit can record continuously for more than two months.  An internal battery backed clock maintains job date and time.  The clock can be set from the front panel or remotely synchronized to the PC over Ethernet.  The standard Rapidlogger can be interfaced with up four milli-ampere sensors, two depth encoders, and two frequency sensors.  Additional sensors can be added via an expansion board. 

Internally the Rapidlogger unit is powered by 24 Volts DC.  However, based on the installation, the unit may be externally powered from a 110/240VAC power supply.  The standard Rapidlogger power supply is shown below.  The supply has internal over current protection.  A green LED on the power supply indicates the presence of power.  The Rapidlogger unit is internally protected by a 1 Amp fuse.  This fuse is field replaceable but it should only be replaced by an electronic technician or an advanced user.  The Rapidlogger is available in two installation configurations.  The first is the unit by itself.  This is a weatherproof unit suitable for installation on oilfield equipment.  In the second configuration the Rapidlogger unit is mounted inside a secondary polycarbonate enclosure.  This is the more common configuration.  It provides an even greater degree of protection from the elements and is suitable for the very rough duty in extreme weather conditions.  The clear front allows for viewing the screen while providing a secondary barrier to ice, rain, sand, and chemicals.

The Rapid VU software for the PC can be used to display the job data in real-time or playback a previously recorded job, and the data downloaded from the Rapidlogger unit is stored in Comma Separated Value (CSV) format for advanced plotting and analysis in programs such as Microsoft Excel It can also be used to prepare a job report for the client if needed.

The Rapidlogger has five different operation modes for the different job types that the system is meant to be used on.  These are the cementing, slickline, N2 and Fracturing pumping, and coiled tubing modes.  Different sensors are used in each of these services and the Rapidlogger accommodates the use of all of these sensors. The menu options on the front panel and internal calculations also differ based on the operating mode.  In all of the modes the operator has the option to run the Rapidlogger in a standalone manner or with a PC running Rapid VU software.  Basic sensor configuration for each operation mode is preprogrammed in to the unit.  This sensor configuration allows the Rapidlogger to know about each of the different sensors that is attached.  It consists of information about the type of sensor, its range, offset, pulse count, etc.  The sensor configuration can be modified in the field from the front panel.  More extensive changes to the sensor setup can be done in the field by using the Rapidlogger Utility program.  This program allows an electronic technician or an advanced user to add new sensors, edit the sensor parameters, change configuration, save and load complete configuration settings from configuration backup files, change the time on the unit clock, calibrate the analog inputs and test network connectivity.

1.1   System Certifications

The ATEX Hazardous area certified version of the Rapidlogger System carries an Ex rating as detailed below.  Note that the units that carry the certification are identified with ATEX labels.

The barrier enclosures is marked:  Description: Ex-Hexagon  II 3(1)(2) G Ex e nA nC [ia] [ib] IIB T4 -20°C ≤ Ta ≤ +60°C.  The maximum temperature is based on testing but cannot be greater than +60°C.  See certificate in Appendix A.  Note that while the system may continue to operate at temperatures exceeding +60C but the certification is only valid for the stated temperature ranges.

All of the the sensors accompanying an ATEX certified Rapidlogger System are marked: see their certificate in Appendix A.

1.3   Monitoring and Recording Data

Upon power up the Rapidlogger unit automatically starts acquiring data from the attached sensors.  The data is also recorded automatically on the internal SD memory card.  This means that no user input or intervention is required for a simple job.  The job data will be automatically displayed and recorded. 

Once the Rapidlogger has been powered up, its screen displays job information in the following format.  While the system only shows up to 6 parameters on the LCD panel, many more parameters can be recorded to the SD memory card and transmitted to the PC over the network.

Monitoring and Recording Data MENU_ROOT

Here each of the displayed parameters has its name and units shown above the data.  On the bottom left of the screen there are three status indicator icons.  The left most icon flashes every time data has been read or acquired from the sensors.  The middle icon flashes to indicate that data has been transmitted over the network to the PC, while the rightmost icon indicates proper data recording activity.  If data is being successfully recorded this icon shows a check mark.  In case the SD flash memory card is full, missing or not operational the check mark is replaced by an 'X'.  The menu indicator on the bottom right shows that the user can to press the F6 key below the legend "Menu" to activate the user menus.

Job data can be downloaded during the job in realtime using the Rapid VU program.  This program can be used to display job data, plot graphs, and generate job files.  The Rapidlogger PC program can also be used to play back previously recorded jobs that have been downloaded from the SD Memory card or those that have been recorded on the PC.  The Rapidlogger records data to its internal memory card in plain text format.  This Rapid VU program records the data in the same format but also creates a copy of every job file it plays back in CSV format and stores it in the same folder on the PC as the other job files.  The CSV format is text files that has comma separated values which can be directly imported into excel for advanced plotting and analysis.

Note:  In Windows 7, XP, 2000, and Vista it is possible to change the “List Separator” character from a comma to another character, this will cause problems in reading the CSV files generate by Rapidlogger.  For example if the Windows operating system is configured for the Latin America region the “List Separator” is configured to be a Semi-Colon.   In this case for the CSV import to work properly the user would have to change the list separator back to a Comma.  This is done from the Windows control panel’s region and language settings.

The Rapid VU program


If needed the job data can be downloaded after the job via an Ethernet cable by using the Rapidlogger Hardware menu in the Rapid VU program.   After the data has been downloaded, the internal SD card should be periodically erased to keep space available for new job recordings.  In general the SD Memory card should be erased with this program or from the front panel menus at least once every 10-20 jobs.  Doing so ensures sufficient space on the SD memory card and prevents data corruption or loss.
