Dear Explorationist,

Considering so many enthusiastic response from previous participants of
the course in 2001, 2002, 2003 we will be organizing the Fieldtrip and
Workshop :

"MARINE CLASTIC RESERVOIR
SEDIMENTOLOGY WORKSHOP"
on June 14 - 17, 2004

Attached to this mail, we include the complete information about the
course. Please have a look, and thanks for your attention. For whom
interested in this course, please do not hesitate to contact us via this

COURSE OVERVIEW

     Understanding sedimentology is one of the basic requirements to a
success in oil & gas exploration.  Although it is hardly noticed,
explorationists use lots of sedimentological principles and concepts in
their daily exploration activity, i.e.: describing outcrop/core,
interpreting logs and seismic, drawing reservoir maps and coal
distributions, and ultimately calculating reserves of hydrocarbons and
coals. This course is aimed to refresh the knowledge of basic clastic
sedimentology with special reference to marine setting; the environment of
which are associated with significant occurences of Indonesian hydrocarbons.
     Back to basic - Look at the rock: is the basic philosophy of the
course. No matter how sophisticated the tools that help us (loggings,
seismic, interpretation software, etc), the success of exploration is still
depend on the geologist (and geology concepts) behind the tools.
Understanding sedimentology gained from this course will hopefully recharge
the explorationist battery to keep on generating prospects (or at least new
ideas) in dealing with the materials (cuttings, core, logs, seismic) and the
tools (software's, etc).
     For new recruits, this course will certainly equip them with necessary
focus on selected sedimentology knowledge to be used in the future works;
while for experience explorationists, this will refresh lots of their
understanding about sedimentology, which probably already built-in
intuitively (sometimes becomes obsolute) in their mind.
     This is the sixth time that a course of this kind (classroom, outcrop
and resort combination) is conducted by GDA. The previous five courses on
August, October 2001 and March, September 2002 , and April 2003 were
conducted at Gunung Walat Sukabumi with a subject on Fluvial-Deltaic
sedimentology. They received many interests and good comments (see: comments
at the end of this letter *). For this marine clastic sedimentology
workshop, the venue will be in Bogor, which will be a combination between
classroom lecturing and exercises, and field-outcrop-description at
Cileungsi dan Cipamingkis Rivers.

Several comments from participants :

..."very good course and field trip".....
..."the topic are very good and meet with
our  expectation"..
...." need more time to classroom and field course"....
.." It's great course!, it's ready good to be back
on the field,  make me  fresh again, because I see
logs too much"...
..."I am recommended to continue the course topic
to the other geologist".
..."need continue this course, karena bagi Geoscience yang tidak  sempat ke
Delta Mahakam bisa ekskursi di Gunung Walat. I  will promote in my company".
..."ada kesempatan banyak untuk lebih mendalami endapan-endapan delta
ditinjau dari sudut pandang field orientation"..
