System Overview
The Warrior Well Logging System consists of a tool interface and power supply panel, a computer, a printer and optional depth, line speed, line weight panel, and perforating power supply. The software supports most cased hole logging tools from a wide selection of tool manufacturers.
The tool interface panel contains the necessary circuits to interface to most cased hole tools, both analog and digital. The depth encoder and line weight interfaces are built into the panel, as is the down hole tool power supply. All functions are digitally controlled from the software, with the power supply having a manual control mode. The panel incorporates data acquisition functions primary DSP based, that interface to the host computer through the industry standard Universal Serial Bus (USB). A seven port USB hub is also incorporated inside the panel allowing a single cable connection to the host computer.
The computer can be almost any machine running Windows 2000, XP, Vista, and Windows 7 32 Bit with a USB port, i.e. rack mount or notebook computers may be used. A second monitor may usually be attached to provide a hoistman's or client's display. The system supports most thermalwell log plotters and a selection of color printers. An optional depth, line speed and line weight panel is available. This panel provides 12 vdc powered, independent depth measurement. It connects to the host computer through the USB and can be synchronized from the host depth or the host depth may be read from the depth panel. An optional perforating power supply is available. The software provides all the usual well logging functions and supports tools from a wide selection of manufacturers.

•The warrior logging
system’s hardware/software architecture make it very flexible and
easy to adapt to different tool/manufacturer’s equipment.
•The hardware is tied into the
software through a script, making it easy to change to match to
different timing and telemetry protocols, without having to do a
multitude of hardware changes, but instead minor software script
modifications.
•These can be done by the user’s themselves,
or if help is needed, can be done by other personnel and easily
e-mailed and installed.
•This makes remote support and tool
additions easy to do without the need to send equipment or staff
away, thus interrupting business operations.
•The Warrior system has all of the
preliminary work done to interface to most tools existing for sale to the independent market.
•Warrior doesn’t build any equipment but
logging systems, so there is no conflict of interest with tool
manufacturers, thus making it everyone’s priority that things work
well for the customer.
•Warrior has and can interface to proprietary
equipment, and will ensure the customer’s best interest and
confidentiality is kept intact.
• Pulse tools, such as GR, Temperature,
Pressure, CNL, etc.
Pulse tools can be measured as ratemeter, or period inputs, polarity
specific.
• Bond tools - Standard bond, radial,
analog/digital combinations
• CNL –telemetry, or multiple pulse
heights - tools have user selectable algorithm files as provided
from the tool manufacturer.
• PL - Lee telemetry, Spartek, CBG, flexstack, Sondex first generation, Sondex ultralink
(*with the addition of sondex hardware), Geofizika, XIPE, Madden, Maxim, Panex, Probe, GO MUXB,etc.
• Multifinger calipers, casing
inspection - XIPE,
Sondex (*with the addition of sondex hardware).
• Hotwell PNN
• Noise tools - all analog tools (have wave file recording capability)
• Freepoint – motorized, spring type,
signal attenuation, pulse outputs, etc.
General Warrior Logging Software Overview
•The
main software acquisition window is setup so that all services
available are put into a list. When picking the service from the list, the tool string is
loaded, a diagram depicting the string comes up, showing the tool
serial number and depth offsets so that the operator can see what it
is that he is running.
After this the tool is powered up and once a database has been
opened, we are ready to log. The steps are essentially the same for all tool combinations. Within the acquisition window there are numerous
parameters/functions that are available for viewing to assist the
operator in the running of the logs.
•Calibrations, sensor data, output(calibrated data), filters, devices.
•Depth shifting(during or after
recording).
•Scale/track, presentation changes.
•Annotations(during or after
recording)
•Hoistman’s display(can put on a
second monitor if desired)
•Gauges – histograms, bar, circular,
semi circular.
•Correlation curves – can be added
from base log.
•Bond/pulse/telemetry windows.

Calibrations / Recalculation
•Calibrations are easily
viewed and modified in acquisition. By looking at the sensors, then the outputs, you can see the
corrections being done.
Eg. If you have a GR
with a gain of 2 you would see the raw count of 10 on the sensors,
on outputs 20, as for all other parameters. This makes troubleshooting easy to see how the raw data is
calculating into what is on paper.
•Filters – are also easy to
understand, eg. Gaussian filter is a depth domain averaging filter,
if the filter length is 0, no filter is applied, as you increase the
length the filter increases. Same for all curves (also have triangular, square options.)
•The CCL also has a threshold that can be
used to minimize noise, it is also a number related to the output. Eg. If you had noise of .5 divisions on a scale of 1 volt/
division, set the threshold to .6, and the noise would be gone.
•Calibrations and thresholds can be played
with live or on recalc, filters only on recalc, or changed before a
log pass.
•Sensors – depth offsets can also be
change/recalculated if somehow a mistake was made.
Bond log / Recalculation
•Bond logs can
be recalculated to change parameters such as gains, gates, travel
time thresholds, ccl noise thresholds.
•Raw data is not overwritten, changes
are made to the pass being created.
•Radial bond normalization – There is
a routine in the recalc module, that can be used to renormalize the
log. It will scan the
hi’s, lo values automatically and adjust the amplitudes to
calibrated values, respectively. Or you can manually pick the spots on the log where you want
to normalize to.
•Calibrations – The warrior system
saves the calibrations specific to the tool serial number, so if 2
calibrations were desired, you could name them independently. There are wellsite zero cals, shop zero, freepipe, and
wellsite internal cals, all available.
•Gates – gates are saved independently
from the cals, so different gate settings can be saved for different
pipe sizes, fluids, etc. and are viewable during the log in real
time.
Multitasking /
Other functions
•While logging,
a multitude of other
tasks can all be performed without halting the progressing of the
present log.
•Heading editor, format editor,
merging, plotting, well sketches, recalculation, plotting,
assembling another log, annotations, can all be performed.
•Merge, splice, TVD – powerful utility
that allows to put logs together, apply TVD corrections by manually
or importing directional data. Depth correction of individual curves, passes, splicing, etc.
over 1 or multiple tie in points.
•Interactive plot/format editor – allows
custom grids, tracks, layouts, colors, trace types to be made/stored
as templates. These
templates can be modified for individual passes, without changing
the masters.
•Well sketch – graphics can be added to the
presentations, as desired.
•Correlation curves – can be added so
that a base log can be displayed while doing subsequent runs, can be
shown only on screen, or saved to the plot.
•Add headings, cal reports, log
passes, diagrams, tracer shot tables reports and so on.
•Add external bitmaps, jpegs, prn
files, metafiles, tiffs, and other utility reports.

Plotting /
Transmission
•Logs can be
plotted to most continuous black and white printers
•Color plotters will plot through
windows to all other regular style printers setup through windows,
but not real time.
•Plot through USB, or parallel port.
•Can plot directly to PDF or TIFF files with
different compressions for data transmission efficiency.
•Databases can be transmitted directly
if not too big, other files are handled as any other PDF or TIFF
file for e-mail, FTP, etc.
•Logs can be recorded in meters,
plotted in feet, or vica versa if need be, with just changing a
units toggle.
Headers /
Utilities
•Headers are easily built and changed
to different sizes, formats, etc. through notepad, similar to an
HTML page.
•LAS import/export capability
•LIS import/export capability
•ODBC import/export.
•Tool
and service editor, to customize tools and services to be used.
•Database export utilities.
•Interpretation tools, Mathpack where you can
apply formulas of your own to data, pipe tally, other utilities for
well properties.
•Printer grid calibrations.
•Depth shifting
•Data management, curve editing, etc.
•Unicode capability being implemented,
for international language translation.

Configuration /
Backup / Updating
•There is an easy way to clone
computer settings from one system to another.If you use the configuration backup utility, it will default
and backup all of the user configurable files that warrior uses. These includes tools, services, gates, calibrations,
presentations, headers, units, pictures, logos, scripts, etc. This
file is roughly around 3-4 MB so is easily transferred, e-mailed,
etc. To clone, simply go to another system, and use the restore
utility, and it will transfer all the configurable files onto that
one. This is an
excellent utility, for use as there can be one person making
changes, and e-mailing them out to the field stations when ready to
implement.
•Software updates – Generally there
are 2-3 new software updates/ year being done. They are downloadable off of the net. To implement, go to the software and go update. This will update the new working files but leave your
configured parameters alone, and will also backup everything with
the old version at that point.
•There is also a real time backup utility,
that allows you to make a second copy of the database, which updates
everytime you stop a pass, in the event that your original database
has a problem, the real time backup is the same data.
Documentation /
Manuals / Training Aids
•Warrior has very extensive documentation,
consisting of over 500
pages of written material in the software manual, some interactive
videos tied into the manual. The hardware documentation and various
small documents aimed at questions asked over the years are on the
distribution CD.
•The Field ops manual, is automatically
loaded with the software, and comes up as an icon in the main
warrior logging screen, handy right there for the users.
•With the installation CD (or off the
web), there are also a lot of extra drivers, etc. for different
plotters, all available in a locale easy to access.
•The
warrior software is available to the general public off of their
website. It is the same software as the acquisition, but without the
authorizing code, does not allow to import/export/gather data. It is meant as a training tool, setup tool, and allows the
user to plot 200 feet of data.
•A tool simulator is also available, which
can be run off of software files, to generate signals to test
hardware, or use as a training device. Any tool can be recorded and made into a simulator file.
Conclusion
This is just a brief overview of the warrior
system, with a lot of other features too numerous to mention. It offers unparalleled flexibility and versatility on tool
choices, with
architecture to handle the simplest to the most complex. It also
