Spectrometric gamma radiation of shale cores applied to sweet spot discrimination in Eastern Pomerania, Poland

This paper describes the application and calculation of hydrocarbon anomalies in two different boreholes located in Eastern Pomerania (northern Poland). Spectrometric data from borehole geophysical probe (borehole 1) and portable gamma logger (borehole 2) were used to analyze shale formations. The results from borehole 1 presented a statistically significant, moderate correlation between calculated hydrocarbon anomalies and hydrocarbon saturation data obtained from well log interpretation. Borehole 2 has been analyzed focusing on the gamma radiation of the core samples, and the positive results of borehole 1. Hydrocarbon anomalies calculated from spectral gamma radiation are reliable indicators of sweet spots, based solely on a cursory evaluation of core measurements. These preliminary information acquired from gamma-ray measurements could help increase sampling precision of further geochemical analysis.

Few medieval swords have been found in Eastern Pomerania, in comparison with other areas of the old Polish state. No sword has been found which dates to the earlier part of the Middle Ages. The 6 oldest swords, dated to the 11th and 12th centuries, were discovered in graves. Some are beautifully decorated. Suggestions about where they were produced are not convincing. Analogies are known from Western Europe, Scandinavia and the Baltic states, which were inhabited in the early Middle Ages by the Prussians. 5 swords from the 13th to the 15th centuries are random finds. Two of them bear the mark of a "running wolf". On one there is an inscription which has been differently read by different researchers. There is no analogy so far. Also discovered were 5 scabbard chapes. In three cases the technology employed in producing these swords was examined. One of them turned out to be a 19th century copy. The two authentic ones were made by bonding soft and hard iron rods. Finds of swords are concentrated in three parts of Eastern Pomerania, the three most important regions of settlement in this part of Poland.
