With the application of modified equation a new permeability equation is developed from porosity and irreducible water saturation. Sedimentary rocks are often tested for their correlation between porosity, (Ø), and permeability, (K). A general trend of increase in permeability with porosity can be expected. Different affections such as, grain size, packing, compaction, and solution or dissolution can influence the relationship between porosity and permeability. The prediction of permeability in heterogeneous carbonate reservoir from well log data is not very accurate. When using conventional core analysis (RCA) and special core analysis (SCAL) a new modified equation becomes present. The empirical equation is used as a base model, evaluated by Wyllie and Rose (1950) which is related to permeability, porosity, and irreducible water saturation. Various empirical models such as, Timur 1968, Tixier 1949 are used to predict permeability from log data for sandstone reservoirs worldwide. In addition to existent proposed equations, we propose an additional equation that also uses laboratory data.
