Abstract Geochemical analyses were used to classify 39 Zechstein (Late Permian Lopingian) Main Dolomite (Ca2) crude oil samples from fields in the eastern and southern sector of the Southern Permian Basin (SPB) of Europe and to provide new insights into the origin of the oil. Geochemical data indicate that Ca2 oils were generated in the early-to-late oil window and are mostly non-waxy oils.

The kinetics of dissolution of dolomite in CO2-H2O systems

Weight loss measurements at different T and PCO2 during experimental investigations of the dissolution kinetics of eight samples of dolomite permitted recognition of a two-stage process. During the first stage which is brief the surface composition of the dolomite becomes enriched with the MgCO3 component and the CaCO3 component dissolves faster.
