| Summary: | Rock is a porous medium which composed of solid matrix, as well as empty spaces
between solids known as pores. To understand its physical properties, in this final
project research, a digital characterization approach (digital image analysis) is
applied on the digital representation of sandstones generated from modeling. One
of the parameters in the modeling used is the implementation of the compaction
factor in the form of degrees of overlap. Models that explicitly implement this
parameter is then referred to as partially penetrated random models. The modeling
has been carried out and the image data has been characterized and analyzed using
a statistical approach. In addition, comparisons to a fully penetrated random
modeling method are also carried out. This study aims to determine the distribution
pattern of the porosity to the degree of overlap and to analyze the characteristics of
several parameters of the porous media structure generated through partial and fully
penetrated random grain deposition-based models. In this study, the characteristics
of the models are then compared with the characteristics of the digital image of the
real sandstone samples obtained from scanning process. The resulting distribution
pattern on the parameter of degree of overlap with porosity shows that the data
obtained through modeling has a quite good precision. Meanwhile, the
characteristics generated by the two types of modeling show a similar trend. The
results of the comparison of the characteristics of the modeling results with the
characteristics of the original sandstone samples show differences. This is because
the grain shape of the model used is still perfectly round. The research can then be
continued by using a more realistic polygon grain shape. |
