Opis:
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 Szczecińska 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 μm. In general, slope of the carbonate platform has better conditions for accumulation of hydrocarbons.

Opis:
The article presents usage of microseismic monitoring for location of microseismic events in polish geological conditions. For location of one synthetic microseismic event, two methods of acquisition were applied: surface and downhole monitoring array. Downhole microseismic monitoring is a technique of recording induced seismicity using receivers placed in the monitoring well near to the treatment well. In case of surface monitoring receivers are placed at the surface. For determination of hypocenter location probability density function was used. Based on provided analysis it is concluded that for polish conditions it is better to use downhole microseismic monitoring. Event located with usage of this technique was located correctly and uncertainty of this location was lower.

Opis:
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.
