Abstract
Relationships between petrophysical parameters were the basis to construct the petrophysical model of the Silurian and Ordovician shale gas rocks in north Poland. The most important was the discussion about relationships between density, i.e. bulk density, skeletal density, grain density determined from various experiments. The differences between density values correlated with TOC and volume of kerogen. Similarly, porosity from different laboratory experiments revealed differences which show the place of kerogen and gas in pore space and skeleton. Including physical adsorption of nitrogen results into Hg porosimetry outcomes enabled extension of pore diameter range into extremely small values. Adsorption of nitrogen method also contributed to porosity values adding notable volume of the smallest pores. The results from NMR experiment confirmed complicated porous space structure and showed that total surface area from adsorption of nitrogen method together with pore space area from Hg porosimetry well correlate with the irreducible water saturation. These results are confirmed by mineral composition and illite/smectite presence. Discussion on density and porosity from laboratory methods of different physical basis is important because these two parameters, apart from mineral or elemental composition are crucial in well logging quantitative interpretation.
