SUBJECT :
PETROLOGY OF THE TERTIARY AGE BASEMENT RESERVOIR ROCKS IN INDONESIA
SPEAKER :
DR. Y. SUYATNO YUWONO
(Faculty of Earth Sciences and Mineral Technology, ITB Bandung)
OVERVIEW
Deal with fractured-reservoir rocks is totally realized very difficult in order
to predict, evaluate, and to solve the relationships of the majortectonic
trends with the detail fracture fabrics, which provide the majority of the
porosity and permeability preservation for fluids or gas to flow. Basement rock
is one of the sweet candidates as the potential fractured reservoir in oil and
gas industries. Several well-known fractured reservoirs are being the primary
target in some companies such as in the Corridor Block South Sumatra (Gulf
Indonesia), Oseil Seram (Kufpec), Cuu Long sub basin in southern Vietnam
region. Therefore, it is very honor forIAGI to invite Pak Yatno to give short
presentation on his expertise in the basement rock petrology.
ABSTRACT
It is understandable that having a drilling program to penetrate the basement
sometime requires more budgets, especially if the primary objective of the well
is much shallower than the basement level. In this case, it is very reasonable
if we have to take benefits of the samples taken from the basement (mostly
crystalline rocks) by evaluating them properly. The more advanced such studies
include petrography, radiometric dating, rock chemistry as well as isotopic
analysis etc. That will provide powerful tools to interpret their petrogenetic
significance of the basement. Subsequently, the tectonic environment can be
interpreted in more accurate ways. The common basement rocks within the
Tertiary Basins in Indonesia can be grouped into two general rock assemblages:
igneous rocks (included volcanic rocks) and the metamorphic rocks. Those two
kinds of rock association need different approaches to study. The igneous rock
assemblage has to be focused intensely in chemistry and mineralogy approaches,
while the metamorphic is needs to be stressed intensely in their mineralogy and
textural aspects. The crystalline rocks emplaced at such tectonic environment
and have distinct petrological characteristics. It is very possible to trace
their tectonic position in time of emplacement if all required-petrogenetic
data are available. In some cases, the knowledge of the petrology of the
basement reservoir rocks may lead us to dissolve the problem of the reservoir
geometry and to identify their geological behavior and nature. In this Luncheon
Talk, some examples will be discussed, especially the igneous ones.
