Exploration of Zechstein Limestone Reefs – Gas Reservoir in the Area of Wolsztyn Ridge

P243 EXPLORATION OF ZECHSTEIN LIMESTONE REEFS – GAS RESERVOIR IN THE AREA OF WOLSZTYN RIDGE Summary 1 In this paper authors will present how difficult task was to reveal and outline the reef bodies within Base Zechstein Limestone formation (Ca1) in the area of Wolsztyn Ridge. Generally over the most of the Basin area Ca1 is deposited as a thick and thin limestone with only a few meters thickness but at offshore zone and on some elevated places over the area of Wolsztyn Ridge forms carbonate organogenic buildups with high porosity (over 20%) and the thickness above 80 m.
