                          Auto-Log
             Copyright (c) 1993 Andrew L. Harrover

      Auto-Log is an AutoLisp program which allows the user to
interactively build well diagrams.  The program draws well
construction details and the well on one side of the sheet
and builds the lithology on the other side.
      This project started when my company was pricing other programs
and was disappointed by the nature of the programs we found.  Most of
the programs could be divided into two classes - one was the very
expensive, million function software with a steep learning curve and
the other was reasonably priced software which produced unsatisfactory
output.  There was no mean between the extremes.  The whole purpose of
this software is that it should facilitate the easy production of
decent looking well logs with a minimum effort by our field people.
This is how AutoLog was started.  I admit that AutoCAD is not a
program that people associate ease of use with, although AutoLog asks
all of the questions.  The only thing left to the operator is to input
the data correctly, plot out the finished diagram and then save it.
There is the possibility that some basic editing might have to be
performed but this could be learned very quickly by a novice or passed
to the CAD staff for a quick polishing and output.  AutoLog was
developed using AutoCAD release 12.

                            SHAREWARE

     This program is not free!  If you try AutoLog and don't find it
acceptable, trash it.  If you try it, like it, and intend to use it,
then PLEASE register the code.  The registration fee is $25.00 for every
copy that you intend to use. I feel this is very reasonable.  When you
register the code, I will send you the latest version and a laser printed
manual.  Registration will also entitle you to future upgrades at a VERY
modest price.

          Please mail your check or cash to:

  I know that getting a check cut for $25.00 by your company can be
inconvenient, but I'm sure your company can make an exception.
Remember - I'm not trying to make a lot of money by writing these
sorts of things but I don't mind a little compensation for all of
the late nights and AutoLisp headaches.  If you pass AutoLog along
to one of your friends then PLEASE pass the entire, unmodified code
and documentation.  Registered users may contact me with questions via
U.S. mail or FAX [phone].

                          LEGAL STUFF

     AutoLog has been tested by me and others and I am almost positive
that there are no bugs in the code.  I have tried to trap as many
errors as possible but I make no guarantee that it will work on your
machine.  Just remember that you use this program at your own risk!!! I am
in no way, shape or form liable for anything that happens as a result of using
this code.

         AutoCAD is a registered trade mark of AutoDesk, Inc.

                            THANKS

     Thanks to GeoTrans, Inc. for providing a machine to work on,
supplies, and a few unlucky souls to debug the code.

                     Items that Deserve Mention



1.   AutoLog draws all items to scale.  The construction details and
     are illustrated inside of an 8" x 2" area.  The user is
     asked to input a total well depth which is divided by eight and
     the resulting figure is the scale.  AutoLog will however,
     continue to ask for depths to all features so that the user can
     format his labels however he pleases.

2.   AutoLog features are illustrated starting from the bottom of the
     well.  The deepest features, which are the well construction
     details, are drawn first and then AutoLog works its way up.  The
     lithology is added next in the same order.

3.   AutoLog makes certain assumptions about well construction
     details.  These are that you have some sandpack, the next layer
     will be the bentonite and the final layer will be grouting which
     will fill the rest of the borehole.  Fill at the bottom of the
     well can be included if desired.  The labels for these items
     are entirely user-supplied and multiple lines of text are allowed
     so there is a good deal of flexibility built in.  In the event
     that one of these layers is missing, a zero (0) can be placed for
     the layer thickness and the tick (') which is placed at the top
     of each layer can be erased.

4.   AutoLog uses a standard AutoCAD font called "romans" so that the
     output is standardized and is very presentable.

5.   AutoLog supports all standard AutoCAD hatch patterns, but more
     can easily be added to the code.

6.   AutoLog hatches all patterns with an angle of "0".

7.   AutoLog lithology and construction labels look best when they are
     kept under fifteen characters.  The max is twenty.

8.   AutoLog version 2.01 only does above-ground well diagrams.  Flush
     installations are planned for future releases.

9.   When AutoLog prompts Y or N for additional lines of text any
     answer except Y will advance the user to the next step.

10.  When AutoLog prompts the user for stratigraphic data it also
     checks to make sure that the sum of the stratigraphic units does
     not exceed the total well depth.

11.  AutoLog works in decimal feet.  Any data which is input in feet
     and inches will be incorrectly interpreted.

12.  The version of AutoLog that has been released is not "crippled"
     in any way.  This is the full, unmodified code.  The idea behind
     AutoLisp is customization of AutoCAD, and I welcome people to
     modify my code.  Please don't send me questions about a modified
     version.  I am, however, open to suggestions and ideas about
     future releases.

                          How To Use AutoLog

1.   Load the code by typing (load "AutoLog").

2.   Execute the program by typing "AutoLog".

3.   The program will begin execution and prompt you for
     information regarding the details of the well construction.  The
     first will be any backfill which may be at the bottom of the
     well.  This is an optional step.  The backfill can be omitted
     altogether by answering "N" to the backfill prompt.  The second
     will be the sandpack section of the well.  The third will be the
     screen attributes.  The fourth, the bentonite seal, and the
     last, the grout from the top of the bentonite.  All of the
     labels can be more than one line.  Remember that AutoLog does not
     add the tick (') after the depth number - this must be added
     manually.

4.   The next section of AutoLog will be the lithology.  The program
     will prompt for the lithology thickness, hatch and depth.  After
     the first layer is complete the user will be prompted for
     subsequent layers.  Entering a thickness which would make the
     unit protrude above the ground surface is prevented.  If the
     user enters a number which would make the unit protrude he is
     asked whether he wants to try again or have AutoLog round it.  If
     the user selects auto rounding, AutoLog uses the remaining
     area for the last section of lithology.  AutoLog also provides
     the user a good deal of flexibility when labeling the lithology.
     AutoLog allows multiple lines of text when labeling the
     lithology.  This allows items such as sample interval and rock
     descriptions to be entered.  The number of lines of text is
     limited only by the thickness of the unit.  If too many lines of
     text are entered, they can overlap the text for the layer
     below.  Remember that AutoLog does not add the tick (') after the
     depth number - this must be added manually.

5.   The next step in AutoLog is to label the drilling method,
     driller, date, who logged the well, ground elevation, top of
     casing elevation, borehole, width, and casing type.  All of
     these fields are prompted and composed of one line each.
