• Seismic interpretation of stratigraphic traps in the central part of the Rotliegend Basin – Golce High
  Seismic data acquired along the experimental profile AGH17511, which crosses the Golce High in the central part of the Mid-Polish Trough, revealed amplitude anomalies related to fluvial sandstone intercalation found within playa deposits, deep below the Zechstein base. The origin of these anomalies was explained using seismic stratigraphic modelling and a porosity model of the Upper Rotliegend deposits, obtained through seismic inversion. The analyses indicate the potential occurence of structural-stratigraphic traps in the southwestern marginal zone of the Golce High, where the reservoir rock is laterally sealed by Zechstein evaporites and top-sealed by playa claystones, as well as stratigraphic traps, associated with sandy lithosomes within the Drawa Formation deposits... dalej
• Chemicals used in industries that carry out work with drilling fluids in the light of the changing business environment
  The end of 2020 and the first quarter of this year brought a gradual increase in the prices of raw materials chemical substances used in production. This is due to their limited availability, resulting from significantly increased demand in China, where the economy has started at full capacity. The disruption of supply chains as a result of the COVID-19 pandemic has affected the availability of containers that have found their way to different parts of the world. This, in turn, has resulted in a significant increase in the prices of maritime transport.
  The main driver of the increase in commodity prices was growing demand in Asia and Europe. China’s industrial production – which has partially coped with the COVID-19 pandemic – has started at full capacity, which is why the demand for raw materials has also increased rapidly.
  This, in turn, caused shortages in the market. Demand has exceeded supply, which implies price increases. Also, the factories producing raw materials at that time did not reach their full capacity, and as high uncertainty due to COVID-19 persisted, it was unclear when they would reach their maximum production and replenish supply... dalej
