| Abstrak/Abstract |
Rock typing is a technique of grouping rocks that have similar properties, which
properties can be in the form of sedimentary, petrophysical, and reservoir parameters.
Classification based on sedimentary parameters is called sedimentary rock type (SRT), while
grouping based on petrophysical parameters is called petrophysical rock type (PRT). The
purpose of this study is to determine the relationship between SRT and PRT in the research
area. The method used to determine sedimentary rock type is to use the facies concept
approach, while the method used to determine petrophysical rock type is the Hydraulic Flow
Unit Method, Global Hydraulic Element, Winland R35, and Pore Geometry Structure. In this
study, determined the relationship between sedimentary rock type with petrophysical rock type,
where some facies that have certain characteristics will have a certain type of petrophysical
rock type pattern. Thoroughly bioturbated mudstone facies which have low porosity and
permeability have two petrophysical rock types with initial sequence (RT 1 and RT 2) with the
HFU, GHE, and Winland R35 methods, while with the PGS method there are RT 4 to RT 7.
These facies have low rock type variations, it can be concluded that these facies are
homogeneous |
