Shale gas potential assessments completed in 2010 for the Baltic Basin (BB) were very optimistic. They placed most of the central part of the BB in the gas window, indicating high prospectiveness of the most of Ordovician, Llandovery and Wenlock deposits. The paper presents results of multicomponent spatial geomodelling, which strongly modify this concept. The model covers area located in the central part of the BB, comprising Kartuzy Szemud and Stara Kiszewa concession blocks. Its area is about 300 km2 and it inc...

Proper estimation of geomechanical parameters of the shale gas reservoir has a crucial influence on the stimulation treatments designing and therefore on hydrocarbon production from unconventional reservoir. The brittleness is the most commonly used parameter for locating the geomechanical hotspots in the reservoir. This parameter can be estimated using elastic, dynamic rock properties such as Poisson Ratio and Young Modulus obtained from sonic logs. The seismic waves velocities recorded by the sonic logging tool ...
