INTEGRATED
SERVICES
We pioneered integrated petrophysics as early as 1973, when we
combined commercial service bureau log analysis with core data and
production test results.
We specialize in petrophysics for reservoir description
(reservoir characterization), in support of field, pool, and basin
studies, and in productivity analysis from logs and cores in support
of reservoir simulations. These analyses require accurate and
calibrated values for shale, porosity, lithology, saturation,
permeability, and fracture intensity, controlled by sample, core,
test, and production history data.
EXPERIENCE
COUNTS:
We have a successful 45+ year consulting track record worldwide,
and offer our services to many oil companies, government agencies,
and consulting firms to augment their expertise. Our experience
covers most active exploration and development areas in the
world. Being an independent
contractor, we can often bring fresh insight and solutions to
difficult problems, with excellent management control to provide
high quality results, on time and within budget.
MILD
MANNERED
MENTORING
We provide mentoring services during projects and instruction in
log analysis and calibration of logs to core and production
data. We have solved in-house workflow and technical problems
for numerous consultants, government agencies, and petroleum
companies.
EASY
EDUCATION
We have taught more than 1000 students in the last 10 years,
in classes ranging from 7 to 25 participants. Courses are based
on
"Crain's Petrophysical Handbook – 3rd Millennium Edition"
by E. R. (Ross) Crain, P.Eng. Extensive customized course notes
and work sessions are provided to suit the needs of the audience,
with patient and personal attention to each student. We have
taught through translators in several languages. Distant learning,
eLearning, and home study materials are available.
FORENSIC
ANALYSIS:
Forensic
petrophysics consists of a review of previous reservoir studies or drilling programs
to find out what went wrong and what went right. This is especially
helpful in horizontal wells that perform differently than expected,
or in simulation studies that are difficult to history-match.
The service has proved to be very beneficial when a consultant
and a client disagree on the petrophysical parameters, results,
or methods used on a project.
SOFTWARE
SIMPLICITY
We pioneered the use of desktop personal computers for
petrophysical analysis in 1976, 5 years before IBM ?"invented"
the PC.
Using our META/LOG petrophysical analysis script, we have recently completed the
analysis of many well known fields around the world. Projects
have ranged in size from a few to 750 wells, spanning up to 700,000
borehole feet in several projects. We mentor clients on
appropriate equations to add to the User Defined Equation sets
embedded in commercial petrophysical packages. Recent jobs
included tar sand evaluation, stress analysis, and elastic
properties.
SOFTWARE DEVELOPMENT:
We
have assisted numerous clients in their petrophysical software
development efforts, and offer advice on coding customized algorithms
into any commercial petrophysical package. Here is a list of
some of the more important projects:
