Out-going
Presidents
Message
As the new CWLS Past-President, this is my last column. I am
very pleased with this years executive committee, together we
have achieved a good deal. It is with some sadness that I pass
the gavel on to the new President, Peter Kubica. It has been a
very rewarding experience and one that Id do again!
In this column, Id like to take this opportunity to thank Ken
Faurschou for organizing a successful AGM on February 8.
I think all who attended enjoyed Dr. Patrick Moores talk. The
talk was both entertaining and informative. Dr. Moore skill-
fully navigated the boundary between Industrial and
Greenpeace debates by giving good factual information and
letting the listeners judge for themselves. Thanks Patrick!
Other highlights were honorary member, Ted Connolly who
provided an entertaining experience for the membership whilst
giving an overview of the 50 years of the Canadian Well
Logging Society thanks Ted!
Worth noting here are the award recipients, Robert Hawkes of
BJ Services who received the $1000 Presidents award for best
overall talk for his outstanding lunch talk last year! In addition
the Vice Presidents award of $500 for best local oil company
paper was given to Peter Kubica of PetroCanada 2 in a row
for PetroCanada, can they make it 3 in a row in 2006?
Once again, thanks go out to all our lunchtime speakers, your
efforts are much appreciated by the society!
So finally, let me introduce your new President, Dr Peter
Kubica.
Peter Kubica is the team leader of the Petrophysical group in
Petro-Canada. He holds a PEng degree in Electrical
Engineering from Slovak Technical University in Bratislava, as
well as an MSc and a PhD in physics from Queens University,
Kingston, Ontario. He started his oilfield experience in 1977 as
a field engineer with
Schlumberger of Canada
in Western Canada and in
the Beaufort Sea. He
joined Petro-Canada in
1980 where he is working
on exploration and devel-
opment projects in
Western Canada and on
the East Coast. He is a
longtime member of the
CWLS, he was a VP in
1995 and participated in
organizing numerous
CWLS conferences. Most
recently he was a chair-
man of the CWLS scholarship committee that made the first
student awards in 2004. He is also a member of APEGGA and
SPWLA.
I congratulate Peter and his new committee and wish them
all the best for 2006!

Editors Note
Welcome to the first InSite publication for 2006! As this is my
first time being exposed to this publication from the inside out,
I would like to say first and foremost thank you very much to
Robert Bercha and Ben Urlwin for their continuing efforts
with respect to putting together such a high quality publication
every quarter of this past year. This magazine takes quite a bit
of effort from a lot of people and between the past executive
and the new executive; I believe we will have our work cut out
for us. I hope I speak for all in saying that we are very excited
and challenged to uphold the standards these professionals
have shown in prior years and look forward to another great
year for the 51st year of the CWLS.
Next, I would like to take this opportunity to welcome the new
and existing membership and sponsorship to the CWLS for
2006. It is great to see the membership numbers continue to
rise as they have. The CWLS has within its membership many
years of experience. It has also proved to be a great continuous
learning environment. The various functions that have been
sponsored by our society allow for a wonderful opportunity to
network and gain valuable friendships in the industry.
As the end of February approaches we are coming to the con-
clusion of what is proving to be the busiest as well as the most
confusing winter drilling season Canada has ever seen. At the
moment there are upwards of 600 rigs currently operating in
Western Canada. The confusing part of course is the weather,
that has not been cooperating to its full potential (i.e. coldness).
Hopefully if the weather holds and begins to get even a little
colder, we will still have a lot of work ahead of us before
breakup. Here is to keeping our fingers crossed for a continued
safe work environment as well as many more wells to be drilled.
This edition of the InSite is once again full of many interesting
topics and discussions. We have two technical papers, the first
of which comes to us from Steve Cuddy on the topic of Fuzzy
Logic. Mr. Cuddy, if you remember gave us a technical lunch-
eon presentation in April, 2005 on the application of novel
techniques to Complex Tight Gas Reservoirs. He first intro-
duced us to the use of fuzzy logic as a petrophysical character-
ization tool in his discussion and has presented his paper here
as a follow up. The second paper also focuses on reservoir char-
acterization using petrophysical analysis. This paper entitled
Petrophysical Analysis in Reservoir Characterization is pre-
sented by R. Baouche and A. Nedjari from the gas fields of
Algeria. Both papers provide some very interesting reading and
we are very happy to make them available to all our member-
ship. In addition to these two papers, our Tech Corner column
provides a review of Coal Bed thickness determination and this
is brought to us by Fred Hyland. Finally we have another great
segment of As the Winch Turns entitled Too Long in the
Bush as well as a the third installment of the Petrophysical
Myth series from long standing member Ross Crain. As is al-
ways mentioned, InSite is continually looking for more mate-
rial and papers to publish. If you have a short paper you wish to
submit, or some new technology and/or analysis that you think
would be beneficial to the membership, contact information for
submittal can be found throughout the magazine, or on the
CWLS website (www.cwls.org).
Enjoy the InSite.
