were made. It is important that personnel are told that genuine mis-
takes will not be a cause for punishment as long as they admit to them
and learned from them. Note: Do not just concentrate on negative
points. Where the job was well planned and executed and performance
was good, show this was the case.
Most final well reports are useless for future well planning. Bulky
printoffs showing operations every 15 minutes are really just
“padding.” Information that is of little or no interest in the future is
readily available from the well files and serves only to make the report
look comprehensive when it may be inadequate. A proper final well
report takes time and effort to produce but looks good and is useful.
Following is a suggested format for a final well report.

3.8.1. Suggested Final Well Report Format

1. Title page with the name of the well and of the report author
2. Table of contents
3. General information
a) Well and rig summary information, plus the date that the well
was spudded and abandoned, suspended, and handed over to
production.
b) Well schematic showing final well status.
c) Time vs. depth graph, showing planned vs. actual performance.
d) Final cost breakdown showing planned vs. actual costs by
category.
e) A summary of good points from drilling the well.
f) A summary of areas of concern or problems encountered while
drilling the well.
4. Drilling operations
a) Description by hole section (text); use the drilling supervi-
sor’s daily diary notes as the basis, along with daily drilling
reports, etc. Write out a description of events. Note especial-
ly information on how best to drill each formation encoun-
tered; include suggested bits, parameters, mud properties,
drilling practices, etc.
b) Bit performance analysis; planned vs. actual performance, con-
straints on bit performance, notes on how the bit and BHA
selection and parameters could be improved.
