Abstract

Isolated carbonate banks in starved basins are very attractive targets for hydrocarbon prospecting. In the Zechstein (Late Permian) Main Dolomite (Ca2) Basin of Western Poland. six such banks or isolated platforms have been penetrated by wells, and gas and/or oil has been found in all of them. The largest is the Chartow Platform, which lies a few tens of kilometres from the edge of the carbonate shelf; and shows well defined facies zonation. Three shallowing-upward cycles may be distinguished in the bank-edge sands, while the central (lagoonal) region and lower slope show a single deepening-upward sequence. Local rapid subsidence, usually Previous HitbalancedNext Hit by the rate of deposition, is inferred for the edge of the Chartow Platform, this subsidence was not Previous HitbalancedTop in other zones.
