F R E Q U E N T L Y A S K E D Q U E S T I O N S
The following questions and answers are those we have been asked in the
past, together with those we'd like to see someone answering if we were
looking for Petrophysical expertise:
What Should I look for in a Petrophysicist?
Most Operators look at price. Because they think that all
Petrophysicists are the same, the cheapest one will do. Of course, this
is a BIG mistake, being how many "discoveries" are overlooked, then
"found" again years later in the files! It is how companies end up
testing water productive zones, or how they end up on the losing end of
a reserves or equity review.
The best way to choose your Petrophysicist is by their track record.
Have they solved problems, or created them? Do they bring knowledge
with them, or get it all from you? Check their CV, looking for
significant contributions made, or new insights that have added value
somewhere.
A good Petrophysicist will cost more in day rate than a bad one, but
they will take less time to do the job, getting it right first time. A
good Petrophysicist will save you a multiple of their cost. A poor
Petrophysicist will lose you a multiple of their's.
Is Your Principal Petrophysicist the Co-Author of the Shell Manual on Capillary Pressure & Saturation-height Functions?
Yes, our Stephen Adams
is the one who wrote the practical (last) half of the above manual.
Since that book was completed in 1993, Steve has increased his
knowledge in the areas of saturation-height modelling significantly. In
fact, a new manual dealing with these issues is in preparation. This
new manual is NOT a Shell document, nor is it based on the existing
Shell manual. It will be available to all to purchase. Current
anticipated publication date is Q4 2007.
Which Companies Have You Worked For?
Clients have included Beach Petroleum, Cairn Energy, Gaffney,
Cline and Associates, Genesis Energy, Inpex, L&M Petroleum,
Methanex, NewField, New Zealand
Government, OMV Australia and New Zealand, Oil Search, Pogo Producing,
ROC Oil, SANTOS, Shell
(various OpCos), Todd Petroleum and Woodside. Repeat business has been
dominant,
suggesting a high level of satisfaction with work delivered.
How Much Do You Cost?
Costs range from US$1600 to $2000 per day (excluding travel,
accommodation & expenses) for consulting, depending on the location
and the work required. The lower end of the range is for New Zealand
based work. Fixed charges can be set for WellEval.com products and can be negotiated for some other services.
Do You Work On-Site?
Yes, we will work in your office if required. Our personnel are
experienced at integrating into a variety of team and cultural office
environments.
We try to encourage clients to give us as much work as possible at our
New Zealand base in an effort to keep costs down. As an incentive, our
lower rates are for N.Z. based work.
What Software Can You Use?
We have experience with a range of petrophysical evaluation systems
used throughout the industry, including Paradigm's GEOLOG, Landmark's
PetroWorks, Terrascience's TLOG and Shell's LOGIC.
Any Examples of Work Done?
This link will take you to some abstracts for published and submitted papers.
Some specific examples that we are able to mention are:
1. Discovery of Mangahewa Gas Field, N.Z.
2. Increased gas reserves in Sangu Field, Bangladesh.
3. Reduced residual gas saturations in Maui Field, N.Z.
4. First Use (Anywhere) of a Borehole Gravimeter for gas saturation, Natih Field, Oman. more
What's Your View on Sustainability?
Our staff hold the view that the dominant Western way of life is unable
to be supported in a sustainable fashion without significant cultural
change or a technological revolution. We are realistic enough to know
that there is little we can do to impact on the cultural element. What
we CAN do is ensure that development of hydrocarbon resources is done
in as efficient a way as possible. We can impact on this efficiency by
ensuring we do our job properly, so that mistakes are not made and
energy is not wasted.
If You're Any Good, Why IS Your Principal Petrophysicist Based in New Zealand?
The photographs at this link answer this question pretty well. They are all taken from within 90 minutes drive of our base.
