KARAKTERISTIK GELOMBANG STONELEY DALAM MENENTUKAN PERMEABILITAS RESERVOIR SUMUR PEMBORAN
Abstract: In-situ permeability
is an important factor in determining whether an economical drilling oil wells to
be mined. Therefore, the calculation in determining the true value of
permeability with an attempt to take a further
decision, whether the
industry is continued
or not. Research
through study literature
is obtained a mathematical modeling
from Matheu and
Toksoz's work which
contains the components
of acoustic waves attenuation factor and rock
permeability factor. Furthermore, by combining some of the concepts and
theories, mathematical models are
used for acoustic
field data logs
and other data
which are required
to get permeability. Data from
the acoustic log is analyzed to determine the time delay for P, S and Stoneley
waves, then determination of
the speed, frequency
and attenuation factor,
especially for wave
Stoneley. In this permeability calculations, it is assumed
that the condition of the rock formations in the area of measurement is a permeable
rock and contains
fractures. The results
show that the
permeability in measurement
area at a depth position indicates suitable with the
data of rock state.
