Digital Sedimentology – a new tool for increasing the value of the pétrographie study

Abstract

Petrographic analysis for a long time has been one of the most demanded methods for determination of material-structural properties of hydrocarbon reservoirs rocks. However, the absence of the governmental regulation of the lithology-petrographic study of reservoir rocks led to variety of the methodological approaches for such studies. Often oil companies have result of multiple petrographic studies of one formation, performed by different contractors, but cannot summarize properly the data. It occurs due both to different methodological approaches of quantitative evaluation of grain size, mineralogy, amount and type of cement, grain contacts, and to different qualification and experience of specialists. Consequently, the question of unification of petrographic data is raised.
