    Compressional ($V_{p}$) and shear ($V_{s}$) elastic waves velocities were determined from logging measurements using FWS tool and acoustic full wavetrains processing using FalaFWS application in GeoWin system. Estymacja program was used to calculate both types of wave velocities ($V_{p}$, $V_{s}$) and bulk density theoretical formulas, which combine quantities dependent on mineral composition, porosity, water saturation and type of medium in the rock. The results were compared with respect to P and S waves slowless, bulk density and dynamic elastic moduli: Young modulus, bulk modulus, shear modulus and Poisson ratio. It was determined that in the absence of $V_{p}$ and $V_{s}$ with a lack of acoustic full wavetrains registration, only the Estymacja program provides the expected results. The FalaFWS application broadens the range of results compared to logging results in depth sections where velocity of mud is higher than the velocity of S wave in formation.

    The purpose of the M.Sc. thesis is a determination and analysis of elastic parameters of rocks based on acoustic full waveforms logs recorded by Full Wave Sonic tool, HalliburtonEnergyServices, in two wells in the Fore-Sudetic Monocline. Elastic parameters were calculated for the Rotliegend sandstones. As a result, the velocity of P, S and Stoneley waves, Vp/Vs ratio, Poissons ratio, as well as Young’s, shear and bulk moduli were obtained. The calculations were made with the use of the FalaFWS application of the GeoWin computer software. Analysis of acoustic full waveforms enabled to specify the elastic parameters of rocks in situ. This paper also includes analysis of relations between calculated elastic parameters and reservoir parameters (porosity and water saturation).
