    The influence of pore media distribution on the elastic parameters of rocks in Miocene sediments (Carpathian Foredeep, Poland, B deposit)
    (Wydawnictwa AGH, 2015) Bała, Maria
    This paper presents the results of modelling compressional and shear wave velocities and elastic moduli, as well as Poisson’s coefficient changes in sandstone-shale rocks, based on the distribution of media reservoir (water, gas) in the pore space. Modelling was performed using the Estymacja-TP computer program and theoretical Kuster–Toksöz and Biot–Gassmann relationships. Phase distribution of saturating pores (ellipsoidal shapes) in several ways was assumed. Calculations were made of elastic parameters in the deposits of the autochthonous Miocene Sarmatian in the borehole B-4. Using a method similar to the so-called »fluid substitution« velocity of compressional and shear waves, elastic moduli, Poisson’s ratio and bulk density, under various conditions of water and gas saturation, were calculated. The assumed change in water saturation ranged from S$_{w}$ = 0% to 100%.

    The object of research - the wells of Malohorozhansk Gas Field. The purpose of study – to design the complex of the geophysical explorations, which will be able to give more accurate to solve geological problems. The methods of research and apparatus - the complex of methods to determine the calculation parameters, Computers. To effectively solve the geological problems is proposed improvement of complex of the geophysical studies to include complex acoustic- pulsed neutronneutron logging, which has several advantages over other. Namely, to clearly define the GWK, WOK, and Cp, Cog. Based on data obtained using a volumetric method can calculate reserves for Malohorozhanskomu field. Also reviewed geological and geophysical features Malohorozhanskoho gas field, the calculations of profitability geophysical surveys and analyzes potential hazards in the workplace, labor protection during exploration.
