Kok harinya Jumat, rek ?
Apa gak sebaiknya diundur/majuken sehari biar tidak kepotong jumatan bagi
yang muslim ?
Thanks atas pemberitahuan disc menarik ini.
Soenoe.

"GEOSTATISTICS FOR SEISMIC DATA INTEGRATION IN EARTH MODELS"
Abstract
In recent years, the use of geostatistics has spread from the world
of reservoir characterisation to that of velocity analysis, time-to-depth
conversion, seismic inversion, uncertainty quantification, and more
generally to that of seismic data integration in earth models. Nevertheless,
many geoscientists still regard geostatistics as little more than a
statistical black-box. By explaining the concepts and applications, the goal
of this course is to clarify the benefits of geostatistics and help
spread its use.
The course will cover the use of geostatistics for interpolation
(kriging...), heterogeneity modelling, uncertainty quantification
(simulation...), and data integration (cokriging, external drift,
geostatistical inversion...). A variety of applications and examples will be
presented, including velocity mapping, time-to-depth conversion,
heterogeneity modelling, and seismic data integration in stochastic earth
models. The relationships between geostatistics and approaches more
familiar to geophysicists, such as filtering or bayesian methods, will also
be discussed, without entering into mathematical details. A number of case
studies will be presented, covering examples from various parts of the
world. This will be a lively course, illustrated by examples, exercises and
discussion sessions.
The short-course presentation, limited to one-day, will provide an
overview of basic concepts and applications. The course document will
provide a support to the course, and further extend some of the more
technical considerations.
As a result of following this course, geoscientists, and more
specifically geophysicists will better understand how geostatistics fits
into their workflow, what tools and techniques they should use depending on
the problem at hand, and what added-value may result from its use.
O. Dubrule has significant teaching experience, through his AAPG
sponsored course « Geostatistics in Petroleum Geology » and through courses
he has
given internally at TotalFinaElf, at the Geological Society (through
Japec) and at academic institutions such as Imperial College (London) and
Ecole des
Mines (France).
This course comes at a time when the use of geostatistics is
spreading in geophysics, as shown by the increase in the number of
geostatistics papers
submitted to Geophysics or Geophysical Prospecting. It should raise
significant interest among both SEG and EAGE members.
WHO SHOULD ATTEND ?
This is a great opportunity for those interested in solving
practical
problems involving data interpolation, earth modelling,
multidisciplinary
data integration or uncertainty quantification
BIOGRAPHY
Dr. Dubrule obtained a PhD Degree in Petroleum Geostatistics at
Ecole des
Mines de Paris in 1981. He then worked for Sohio Petroleum Company
in the
USA (1982-1986), Shell International in The Netherlands (1986-1991)
and,
since 1991, he has been with Elf and TotalFinaElf, working in France
and in
the UK. During his career, he has held a variety of staff and
management
positions where he developed and applied new techniques for
reservoir
characterisation, earth modelling, risk analysis and uncertainty
quantification. After leading the « Earth Modelling and Uncertainty
Quantification » group at TotalFinaElf, Dr. Dubrule recently became
manager
of Geoscience Training and Communication.
Dr. Dubrule has authored more than twenty papers in the field of
geostatistics and earth modelling. In 1991, he received the
President's
prize of the International Association of Mathematical Geology, for
"Outstanding Contribution to Mathematical Geology by an individual
35 years
or younger". In the last decade, he organised and chaired a number
of
events organised by SPE, EAGE, SEG or AAPG. Dr. Dubrule is the
author of
AAPG Course Notes Series #38 "Geostatistics in Petroleum Geology",
and
editor (with E. Damsleth) of "Petroleum Geostatistics" a Special
Issue of
EAGE's Petroleum Geoscience Journal, published in 2001.
