Software Overview

The goal of our software is to help a user complete a task as fast as possible while maintaining
high quality output and flexible formatting. Our software’s graphical user interface, simplified
file system, and drawing tools make it more user-friendly than competing software. The
following is a list of our products:

QuickLog

QuickLog greatly speeds and simplifies the process of creating boring log/well construction
diagrams. Featuring a point and click graphical interface, it's intended for use by geologists or
data entry staff members to create diagrams without the need for a CAD system. Hundreds of
different formats can be created without programming or lengthy formatting.




QuickCross/Fence

The QuickCross and QuickFence modules use data already entered in QuickLog to create 2-D
cross sections and 3-D fence diagrams. Using the drawing tools, you can edit the drawings
right on the preview screen.




QuickGIS - QuickSoil

QuickGIS enables you to organize the lithology data for a set of borings into a table of X, Y, Z
coordinates so that it fits the formats needed for exporting to most 3-D modeling programs
such as ArcView and EVS. QuickSoil produces a soil analysis table that shows soil sample test
results for a set of parameters. Each sample is placed at its correct depth and shaded
according to the value of each parameter tested. It makes it easy to see the areas of
contamination throughout the different layers of soil.




GW Assist - ChemGraph

Groundwater Assist extracts pertinent groundwater data from raw lab data files and adds it to
historical data in Excel tables or other types of databases. Thus, each time you sample, you
avoid tedious data entry. ChemGraph is an Access database and report writer. It enables you
to quickly produce groundwater tables, graphs, and maps.

of our users.

License Options

Stand-Alone - The program is registered via the Internet to work on one computer only.

Hardware Key - You are given a hardware key which plugs into the USB port. Multiple users
from the same physical office may share the key.

Network - Users share a license that is stored on M-Tech's Internet server -- therefore, no
network setup is needed, just an Internet connection. When the program is run, the license
server is checked to verify that one user is logged on per license purchased. All users must be
in the same physical office.

Pay-As-You-Go Network - You may install the software to as many computers as you like and
have multiple users in any number of locations. You are billed per hour of usage. When a user
logs into the program, he or she enters a username, password, and other parameters such as
"Job No." This way, usage can be tracked by project and re-billed to your clients. Billing is
done very precisely in 6 second increments, and the program can be paused anytime. If a user
leaves the program running, it automatically pauses after 2 minutes of inactivity.

Cost Analysis

QuickLog

Depending on your current method of creating boring logs, you should save 15 minutes to 1
hour for each log you create. Below is a cost analysis table of savings based on the number of
logs you do with an employee hourly rate of $25 per hour:

Logs/Month      Hours Saved/Month          $ Saved/Month         $ Saved/Year
5               1.25 to 5                  $31.25 to $125        $375 to $1500
10              2.5 to 10                  $62.50 to $250        $750 to $3000
20              5 to 20                    $125 to $500          $1500 to $6000


QuickCross/Fence

By importing QuickLog data and placing the borings to scale, QuickCross/Fence immediately
saves about 2 hours per cross section. If you are creating more complex cross sections, you'll
save even more time with its drawing tools (nodes between layers, lens fill, etc.) that are
more efficient than AutoCAD (and similar programs) for this specific task. For the table below,
we'll estimate that 4 hours are saved for each drawing and use an hourly rate of $40 (since a
draftsperson or geologist would be doing this task):

Cross Sections/Year       Hours Saved/Year        $ Saved/Year
5                         20                      $800
10                        40                      $1600
20                        80                      $3200


Pay-As-You-Go License

With this option, the software is installed on everyone's computer. So, the licensing system,
alone, should increase your efficiency -- no waiting for software on a dedicated computer to
become available, no looking for hardware keys, no handing off logs/cross-sections to a
draftsperson, no managing licenses by IT staff. The cost is $10/hour.

For the table below, we’ll estimate that a $25/hr QuickLog user can save 30 minutes to an
hour per log. Similarly, we’ll estimate that a $40/hr Quick/Cross Fence user can reduce the
drawing time from 6 hours to 2 hours:

Quickog Features


Create Log Format Quickly, Without Programming

To create the header and footer, you choose the paper size and then "drag and drop"
elements:




You can completely customize the header and footer. Below are some samples:
The body of the log is created "on the fly" by listing the column types to be shown from left to
right. You can add, delete, or re-order these columns any time, even after you have entered
data. Perhaps, you decide to add a lab test months after you have finished a set of logs --
inserting another column is no problem! Other logging programs, on the other hand, require
the format to be pre-programmed before data can be entered.




The resulting columns on the log are shown below:




Export Logs to Other Graphics Programs & CAD, if Necessary

After you've completed your log, you can simply print it, or you can export it to one of the
following graphic formats: DXF, BMP, WMF, EMF.


Easy to Use File Format, Export Log Data to Other Databases and Modeling Programs

When you save a log, its data is saved in a single file (ending in ".BOR"). This method makes
it easy to share logs with clients and colleagues (just email the .BOR files). However, if
needed, QuickLog also features database import capability. You can select multiple .BOR files
to be condensed into one file which can be read by a database. Conversely, a database can
export its data into one file containing data for multiple borings. QuickLog can parse this file
into multiple .BOR files, ready to be viewed and/or printed.

Using QuickGIS, you can also export QuickLog data into other modeling programs such as
EVS, GMS, and Arcview.
QuickLog - Data Entry

QuickLog's "point and click" interface makes data entry a breeze! When you open a log, it is
shown on the preview screen. Just click wherever you would like to add or edit data:




A data entry editor then "pops up" pertaining to the area clicked. In the editor, you enter new
data, make changes, and click "OK." The log is then updated on the screen. This simple
interface makes the program easy to learn, and it makes it easy for those who do not use it
regularly to "remember" how to use it when the time comes:
To speed entering soil and rock descriptions, you may set-up lists of often used description
phrases (ex. "SAND, Poorly Graded," "yellowish brown," "traces of silt," etc). Then, you simply
click on these phrases to have them placed in the description text box, above. Also, you can
use this method to standardize description entry so that your logs become more consistent.




Drawing Tools

QuickLog features a rich set of drawing tools that enable you to add lines, text, and objects
using the mouse, directly on the preview screen. Need to add a special feature that is not pre-
programmed in the software? You can do it quickly using the drawing tools.
Create Custom Fill Patterns using any Paint Program

The program includes 65 fill patterns. Each fill pattern is a BMP file which you can open and
modify using any paint program. This format enables us (and you) to create a wider variety of
fill patterns than a CAD program can offer (since CAD can only use vector fill patterns). Any
BMP file can be used as a fill pattern -- you could even take digital photos of your soil samples
and use them as fill patterns. Below is the dolomite .BMP file in a paint program:




Grain Size Analysis

QuickLog is the only logging program (that we know of) to offer the highly specialized grain
size analysis graphic column. Below is an example featuring Grain Size Analysis, Porosity,
Depositional Environment, Sedimentary Structures, Facies, and Oil Stain.
QuickCross/Fence Features

The data from QuickLog is easily imported into QuickCross and QuickFence. Below is the cross
section data for 4 borings:




 Below is a cross section generated from the list above. Each geological layer is marked with
its fill pattern abbreviation (ex. SM). In minutes, you have a basic cross section drawn
perfectly to scale. Accomplishing this task in CAD would take hours.
In addition to labeling the layers, you may choose to have them filled with a fill pattern inside
the representation of the borehole:




You also have the option of letting the program connect the geological layers using its artificial
intelligence:
Drawing Tools

What really makes QuickCross/Fence outshine its competition are its drawing tools which
enable you to manipulate the drawing right on the preview screen. Geological layers are often
tricky and require a human touch to accurately recreate them. With QuickCross/Fence, you
can quickly add layers, lenses, lines, text, and symbols. You can start by having the program
connect the layers automatically, and then you can "clean them up," if needed.

Other cross section programs generate a basic cross section then require you to import it into
a CAD program to finish it. Not only does QuickCross/Fence save you from this extra step, but
it has some important advantages over using CAD. First of all, QuickCross/Fence has tools
specifically designed for creating cross sections more quickly. For example, it places nodes at
each contact point between the geologic layers. To add a new layer, you simply connect
nodes. You can add your own nodes to control how layers pinch out between borings, and you
can use the lens tool.




Sample logs, cross sections, and fence diagrams are shown on the pages that follow. The fill
patterns, when printed, are better quality than those shown here due to the conversion to PDF
format.
