Summary:
Research area shows 3 distinct rock types, RT 1, RT 2, and RT 3 (lacks of data). RT 1 has the highest permeability, compared to RT 2, and RT 3 (lowest). The permeability is very dependent on pores, which has strong relations to diagenetic environment. Diagenetic processes have implications on pores and cement forming. Cement formed by diagenetic process are bladed isopachous (calcite), formed in fresh water phreatic environment and fibrous isopachous (aragonite), formed in marine phreatic environment. Pore formed by dissolution shows vadose zone
