The loss of elastic energy to the medium can be quantified by the quality factor Q. Acoustic full waveforms log from Winna Góra1 borehole were used to estimate P-wave quality factor. Data used in this paper were analyzed with usage of GeoWin software. Interpretation of acoustic full waveforms was performed for the one pair of waveforms. The most important part in the interpretation of data is manual picking of P wave arrival, calculation of semblance function, and picking anomalies of P wave on amplitude spectrum. Using data from interpretation of acoustic full waveforms, we calculated quality factor. Based on provided analysis it is concluded that the highest attenuation ( so the lowest Q) is observed in Rotliegend strata.

: The study area in geological sense is located on the Grotów peninsula within Gorzów Block in north-western part of Poland, on the border of Fore-Sudetic monocline and Szczeci ń ska Through. In that area two generalized sedimentary zones were recognized: carbonate platform (barrier and platform plain) and slope of the carbonate platform (edge of the slope with bay plain). The aim of this study is the analysis of the relationships between petrophysical parameters of the carbonate reservoir rocks. This research was conducted on the base of mercury porosimetry for 318 rock samples. The analysis showed that not all pore space is available for the accumulation of hydrocarbons. Availability of pore space for accumulation strongly depends on the average capillary, and the amount of pores with diameter higher than 1 μ m. In general, slope of the carbonate platform has better conditions for accumulation of hydrocarbons.

The Tamazert-Jijel kaolin deposit is located in eastern Algeria, It was formed during a process of hydrothermal alteration of feldspars rich in potassium. Kaolin, obtained at the mine, mainly contains varying amounts of impurities such as iron oxide (Fe2O3) and anatase (TiO2). These components negatively affect the quality of the commercial product. This research was performed to improve the quality of kaolin to be used in the paper industry with the goal of reducing the impurities of iron and titanium oxides. Different sized fractions of the original sample were analyzed by XRD. The results obtained showed that the mineralogical composition is: quartz, muscovite, kaolinite, dolomite, albite and orthoclase. Kaolin, like all clays, has a thin dissemination of minerals throughout it. After processing kaolin, the particle size fraction of less than 45μm, corresponding to the liberation mesh size, was retained for purification by chemical treatment with different acids of different concentrations (hydrochloric acid, sulfuric acid, acetic acid), heated to boiling point temperatures. The kaolin samples treated with the various acids above were analyzed by X-ray fluorescence and by XRD. The results obtained from the sample treated with hydrochloric acid show that the iron oxide content of acid is reduced by 1.65% to 0.88%. Meanwhile, the brightness of the sample reached 90% under the effect of the treatment with hydrochloric acid at concentration of 2 mole/dm.
