Prospectivity analysis of oil shales in Kazakhstan

Abstract

Oil shales in Kazakhstan have been studied to some degree but have not reached the operational stage. This study conducts a prospectivity analysis using data from more than 12 deposits. Relationships between ash content and calorific value, as well as oil content and calorific value, were determined. Prospectivity criteria considering the type and quality of oil shales, tonnages of mineable reserves, and excavation depths were proposed, offering useful insights for estimating quality characteristics and potential utilization areas of oil shales in Kazakhstan.,
