WELLOG IS IN THE BUSINESS OF SENSING, ACQUISITION, LOGGING AND PRESENTATION OF DATA.

 

WELLOG DESIGNS MANY TYPES OF DIGITAL DATA LOGGING SYSTEMS. THESE SYSTEMS MEASURE ANALOG SIGNALS AND CONVERT THEM INTO A BINARY (DIGITAL) FORM. THE LOGGING SYSTEM STORES DATA ON MEMORY STICK, HARD-DRIVE, CD ROM OR FLOPPY DISK AS REQUIRED BY THE END USER.

 

WIRELINE WELL LOGGING:

 

[WIRELINE DEPTH INDICATOR]           

 

BRIGHT “DAYLIGHT” DISPLAY. THIS DEPTH INDICATOR USES A STATE-OF THE ART MICROCONTROLLER THAT DECODES STANDARD QUADRATURE ENCODER SIGNALS INTO A FOUR TO EIGHT DIGIT DEPTH DISPLAY.  THE DEPTH CAN BE LOGGED WITH TIME STAMP FOR MEMORY TOOL LOGGING APPLICATIONS.

 

DEPTH DISPLAY 00000.00 TO 99999.99 FEET.

 

OPTIONS INCLUDE UP/DOWN DEPTH OUTPUT FOR INTERFACING TO ACQUISITION SYSTEMS AND DEPTH ALARM FOR INDICATION OF TOOL APPROACHING THE SURFACE WHEN LOGGING.  DEPTH INDICATORS ARE AVAILABLE WITH DOT MATRIX LED AND LCD WITH BACKLIGHT.

 

USER SELECTS DISPLAY OF FEET IN INCREMENTS OF .2 FEET, .1 FEET OR .01 FEET.  WELLOG HAS VIRTUAL DEPTH COUNTERS TOO!

 

VIRTUAL PANELS. YOU CAN SEE THEM BUT THEY AREN’T REALLY THERE!

 

[WIRELINE WEIGHT INDICATOR]         

 

BRIGHT “DAYLIGHT” DISPLAY. THIS WEIGHT INDICATOR INTERFACES DIRECTLY WITH STANDARD POTENTIOMETRIC WEIGHT SENSORS GIVING AN IMMEDIATE INDICATION OF WIRELINE WEIGHT.

 

WELLOG HAS VIRTUAL WIRELINE WEIGHT INDICATORS.

 

WELLOG CCL BEEPER:

 

WELLOG HAS DEVELOPED A HANDY AUDIBLE CASING COLLAR LOCATOR (CCL) BEEPER.

 

ASK ABOUT THE “VIRTUAL” CCL BEEPER. YOU CAN’T SEE IT AND IT ISN’T REALLY THERE! YES, ASK WELLOG!

 

WELLOG  LOGGERS:

 

[V20 LOGGER]              [V30 LOGGER]              [V40 LOGGER]

 

 

WELLOG IS CONTINUALLY IMPROVING LOW COST – HIGH PERFORMANCE LOGGING SYSTEMS BASED ON SINGLE CHIP MICROCONTROLLER AND DSP DESIGNS.

FOR REMOTE LOCATIONS, YOU CAN FLY IT IN OR EVEN BACK PACK IT IN.

 

THE LOGGERS OPERATE WITH OR WITHOUT A SIGNAL CONDITIONING MODULE TO PROVIDE A COMPLETE EIGHT TO THIRTY TWO CHANNEL DIGITAL LOGGING PACKAGE. THE SYSTEM SENDS LOG DATA PACKETS VIA HIGH SPEED SERIAL/USB CONNECTION TO A DESKTOP OR LAPTOP PC FOR DATA STORAGE IN STANDARD LAS FORMAT OR ANY OTHER SPECIFIED FORMAT.

SEISMIC LOGGER:

 

WELLOG INTRODUCES A NEW MULTI-CHANNEL SEISMIC LOGGER. CAPTURES SINGLE OR MULTI-CHANNEL GEOPHONE DATA, STORES IT IN MEMORY AND DOWNLOADS TO PC. THE 4K to 400K SAMPLE PER SECOND SAMPLE RATE WITH 16K SAMPLE MEMORY AND START – STOP TIME STAMP OFFERS A QUICK SOLUTION TO SEISMIC ACQUISITION REQUIREMENTS.

 

THE WELLOG 3 AXIS SEISMIC LOGGER IS AVAILABLE NOW!  THREE CHANNELS ARE ACQUIRED AT 100K SAMPLES PER SECOND. TIME STAMP FOR START AND STOP TIIMES IS STORED WITH EACH SCAN. DATA IS STORED ON PC HARD DRIVE.

 

ACQUISITION IS INITIATED BY CONTACT CLOSURE AT INSTANT OF SHOT-SOURCE IMPACT.

 

WAVEFORM DATA MAY BE PRESENTED IN GRAPHIC FORM USING READILY AVAILABLE METHODS.

 

THE WELLOG SEISMIC LOGGER PROVIDES DEPTH TO WATER TABLE, DEPTH TO BEDROCK AND OTHER DATA.

 

DIGITAL LOGGING TOOLS:

 

WELLOG IS COMPLIMENTING SURFACE ACQUISITION SYSTEMS WITH SLIMHOLE LOGGING TOOLS. WELLOG LOGGING TOOLS USE STATE-OF THE-ART SENSORS AND MICROPROCESSOR TECHNOLOGY.

 

LOGGING TOOLS ARE SLIMHOLE 0.50”, 1.10”, 1.375”, 1.625”, 2.00” DIAMETER.

 

OUR SMALL DIAMETER FLUID RESISTIVITY LOGGING TOOL IS ONLY 20 INCHES LONG, 1.10 INCHES IN DIAMETER.

 

TOOLS OPERATE IN DEPTH REFERENCE OR MEMORY (TIME) LOGGING MODE

 

PROTOCOL CONVERSION:

 

WELLOG CAN CONVERT ANY PROTOCOL YOUR TOOL PROVIDES INTO A HIGH SPEED SERIAL DATA STREAM THAT IS PC COMPATIBLE.  FILE MANAGEMENT IS DONE IN LAS FORMAT FOR EASY EXPORT TO MS-EXCEL OR OTHER OFFICE PRESENTATION PACKAGES.

 

PROTOCOL TYPES:

 

ANALOG TO RS-232

ANALOG TO RS-422

ANALOG TO RS-485

ANALOG TO PULSE FREQUENCY

ANALOG TO FSK

ANALOG TO PSK

ANALOG TO QPSK

ANALOG TO BIPOLAR PULSE

 

 

BACK PACK LOGGER:

 

GEOPHYSICAL LOGS ARE SOMETIMES NEEDED IN AREAS HAVING LIMITED ACCESS.  WELLOG IS MEETING THE CHALLENGE WITH A 1000 FT. SELF-CONTAINED DSP-LOGGER SYSTEM THAT WEIGHS LESS THAN 50 LBS. DEEPER SYSTEMS ARE AVAILABLE TO MEET ALMOST ANY SPECIFICATION.

 

HARDWARE:

 

MANY TIMES IN HYDROLOGY, GEOLOGY, MINING, ENVIRONMENTAL AND OTHER DISCIPLINES, SPECIALIZED HARDWARE, INSTRUMENTATION, OR SENSORS ARE NEEDED. FOR EXAMPLE; IP, SP, E-LOG, GAMMA, SEISMIC, ACOUSTIC, PRESSURE, TEMPERATURE, FLOW, DEVIATION, AND OTHERS!

 

 DO YOU NEED A DEDICATED STAND-ALONE DATA ACQUISITION (DAQ) AND LOGGING SYSTEM?

 

WELLOG HAS MICROPROCESSOR BASED, LOW COST, HIGH PERFORMACE LOGGING SYSTEMS.

 

WELLOG LOGGERS ARE PORTABLE EIGHT CHANNEL LOGGERS WITH 10 OR 12 BIT RESOLUTION. THEY CAN ACQUIRE 5 SAMPLES PER FT. AT UP TO 600 FEET PER MINUTE OR 10 SAMPLES PER FT. AT SPEEDS UP TO 300 FT. PER MINUTE.

 

THE WELLOG LOGGERS ACQUIRE ANALOG DATA, CONVERT TO DIGITAL LAS FORMAT AND SENDS THE DATA TO A LAPTOP OR OTHER COMPUTER FOR STORAGE AND PRESENTATION.

 

WELLOG LOGGERS CAN DO ACOUSTIC VDL LOGGING.

 

IT IS A HIGH-SPEED DSP BASED LOGGING SYSTEM THAT MAINTAINS PORTABILITY AND LOW COST WITH ADDED PERFORMANCE.

 

MEMORY LOGGER:

 

WELLOG HAS COMBINED DATA ACQUISITION WITH TIMEKEEPER ™ TECHNOLOGY. THE WIRELESS MEMORY LOGGER CAN ACQUIRE SINGLE OR MULTICHANNEL DATA AT 1 TO 500000 SAMPLES PER SECOND, STORE IN MEMORY WITH TIME STAMP AND RETAIN DATA UNTIL DOWN LOADED TO YOUR PC. FOR APPLICATIONS THAT REQUIRE LONGER SAMPLE PERIODS, THE MEMORY LOGGER CAN LOG ANY INTERVAL OVER TWENTY YEARS! IT USES MANUAL TRIGGER, TIME TRIGGER OR EXTERNAL (EVENT) TRIGGER.

 

CUSTOM DESIGN:

 

IF YOU CAN’T FIND WHAT YOU NEED, WELLOG CAN PERFORM MICROPROCESSOR/MICROCONTROLLER/ DSP DESIGN & DEVELOPMENT FOR CUSTOM SMART SENSOR LOGGING APPLICATIONS INCLUDING DOWNHOLE MEMORY LOGGING.

 

SOFTWARE:

 

WELLOG CAN BACK UP THE HARDWARE WITH SOFTWARE!

 

WELLOG IS CAPABLE OF DEVELOPING LOW LEVEL MICROCONTROLLER/DSP, MIDDLE-LEVEL DOS AND HIGH LEVEL LABVIEW OR WINDOWS XP SOFTWARE FOR YOUR LOGGING APPLICATION.

 

LOW LEVEL:

 

THE LOWEST LEVEL SOFTWARE OPERATING AT THE MICROPROCESSOR LEVEL IS FAST AND EFFICIENT. SOFTWARE DEVELOPMENT IS DONE ‘IN HOUSE’ SO WE KNOW WHAT THE SOFTWARE IS DOING AND WHEN UPGRADES OR ADDITIONAL FEATURES ARE REQUIRED, WE CAN MAKE CHANGES QUICKLY AND EASILY.

 

MIDDLE LEVEL:

 

SOFTWARE DEVELOPED IN AN MS-DOS ENVIRONMENT ALLOWS COMPACT EXECUTABLE SOFTWARE TO BE PRODUCED THAT IS COPIED ON DISK AND REQUIRES NO INSTALLATION.  MS-DOS EXECUTABLE SOFTWARE IS FAST, EFFICIENT AND RELIABLE. NO UNEXPECTED WINDOWS SHUTDOWNS.  MS-DOS SOFTWARE CAN BOOT DIRECTLY ON POWER-UP.  NO OTHER SUPPORT SOFTWARE OR OPERATING SYSTEM IS NEEDED. THE WELLOG “DAS GUI” IS A DATA ACQUISITION SYSTEM GRAPHIC USER INTERFACE (30k bytes executable) THAT GIVES THE LOOK AND FEEL OF A “REAL” CONTROL PANEL USING “VIRTUAL” PANELS THAT RESIDE ON SCREEN. THE USER NAVIGATES USING CURSOR CONTROL KEYS TO SELECT AND CHANGE CONTROL SETTINGS ON THE VIRTUAL PANEL. A FIXED OPERATING SYSTEM HAS ADVANTAGES. WHEN OTHER OPERATING SYSTEMS ARE UPGRADING, INCOMPATIBILITIES MAY OCCUR BETWEEN PROGRAMS AND THE NEW OPERATING SYSTEM.

 

HIGH LEVEL:

 

FOR THOSE WHO PREFER A WINDOWS ENVIRONMENT, WINDOWS SOFTWARE GIVES A COMPLETE USER FRIENDLY PACKAGE. WELLOG WINDOWS VIRTUAL PANELS. ASK ABOUT OUR NEW WINDOWS XP (45K bytes executable) WELL LOGGING SOFTWARE!

 

 VIRTUAL PANELS:

 

TEMP_PANEL    ELOG PANEL     CALIPER PANEL            GAMMA RAY PANEL   

 

VIRTUAL PANELS ARE LAUNCHED JUST LIKE ANY OTHER WINDOWS APPLICATION. PANELS MAY BE MOVED AROUND, MINIMIZED WHILE OPERATING IN A REAL TIME LOGGING ENVIRONMENT.  VIEW ONE PANEL OR TEN PANELS.  WINDOWS VIRTUAL PANELS OPERATE THE SURFACE AND TOOL ELECTRONICS. DATA IS STORED FOR PLOTTING IN THE USUAL LOG PRESENTATION.

 

REAL TIME:

 

THE BEST OF BOTH WORLDS IS AN APPLICATION THAT TAKES ADVANTAGE OF THE HIGH SPEED ‘REAL TIME’ ACQUISITION CAPABILITY OF A MICROPROCESSOR AND ALSO HAS THE USER-FRIENDLY INTERFACE OF A WINDOWS OPERATING SYSTEM, DAS GUI, OR VIRTUAL PANEL.  REAL TIME OPERATING SYSTEMS (RTOS) CAN MEASURE HIGH SPEED EVENTS WITHOUT INTERRUPTION AND COMMUNICATE WITH A HIGH LEVEL OPERATING SYSTEM.  HIGH LEVEL OPERATING SYSTEMS ARE OFTEN NOT ABLE TO DO THE FAST EVENT CAPTURE THAT A REAL TIME OPERATING SYSTEM CAN.

 

WELLOG SOFTWARE CAN OUTPUT DATA IN ANY FILE FORMAT FOR EASY EXPORT TO MOST PRESENTATION PACKAGES.
