Relationships between porosity and permeability of calcarenite rocks based on laboratory measurements

Fluid transport into porous materials is an area of study relevant to many scientific and engineering fields such as hydrogeology,geoenvironmental engineering,petroleum engineering,chemical engineering and physics. permeability and porosity are two of the primary properties that control the movement and storage of fluids in rocks. they represent important characteristics of materials. in the present study,basic petrophysical properties of calcarenite rocks were measured,and their relationships are discussed. permeability and mercury intrusion porosity,and pore size distribution were determined. furthermore,bulk and particle densities of rocks were determined. permeability and porosity are closely related to each other in very good direct proportional relationship,i.e.,with increasing porosity,permeability increases as well. this relationship is influenced by other rock properties,such as the amount of open and closed pores within the rock sample,as well as pore size,and distribution. from this point of view,it is necessary to study these petrophysical properties of calcarenite rocks that are commonly used for historical monuments,because this enables an overall analysis of rocks and its possible use for engineering constructions and renovation of historical monuments.
