The analysis of petrophysical characteristics for different types and subtypes of reservoir rocks of WOGR, in particular, clay limestones, consolidated deep-lying, porous, compacted and dense clay sandstones is carried out. Optimized empirical relations with a multiplicative component for pressure and porosity are constructed for them. A method for supplementing the parametric base of compressibility according to the data on body waves velocities and a method for estimation of fracturing and permeability of rocks in the interlayers of well sections have been developed. Additional (within the framework of the previously created predictive method) methods of distinguishing oil and water in the rocks of well sections by rock compressibility and by the density of fluid – pore filler have been developed. The use of these developments significantly increases the reliability of predicting the oil and gas potential of well sections, in particular, in low-porosity (including shale) reservoirs.
