Abstraksi:Ductile components including rock fragments, clay, and matrix material are often con¬sidered as the most important factors that control quality of shaly sandstones, which are usually characterized by low porosity and permeability. In presence of ductile compo¬nents, the degree of quality reduction is affected mainly by distribution, occurences, and amounts of the ductile components. Therefore, the presence of ductile components affects rock petrophysics, and consequently has effect on fluid movements in reservoir during production. This paper presents results of the study on plug samples taken from five wells from various fields in Cooper Basin (Tirrawarra Sand), South Australia. The samples were stud¬ied petrographically using x-ray diffraction, optical petrography, and scanning electrone microscope. The results were integrated with routine and special core analysis data. The overall results show that the distribution and the amount of ductile components have sig¬nificant~v reduced porosity, hence the quality of the reservoilc However, the effect is differ¬ent for different types of porosity, and this certainly is valuable addition to our under¬standing over permeability behavior of shaly sandstones.
