    Opis:
    The research material were reservoir waters separated in mine installations (well separators located in dolomite formations, Zechstein limestone and Rotliegend sandstones) working in the Polish Lowland. The results of physical and chemical analyses of the research material were used to simulate mixing of various waters. The simulations were made using the AquaChem computer program. Possibilities of carbonate precipitation (Langelier saturation index, Ryznar stability index) and corrosivity (Larson-Skold index) of the analysed waters and their mixtures were determined. The obtained simulation results of mixing water with various physical and chemical parameters were confronted with the results of tests of their compatibility carried out in laboratory conditions. The conducted tests of reservoir water compatibility, carried out in terms of their safe storage in absorbent wells, have shown that waters from deposits in the same reservoir rock are compatible with each other. In the case of mixing waters from different deposits, their incompatibility has been noted many times. It is therefore necessary to perform physical and chemical analyses of mixed waters each time before they are injected. The obtained results will be helpful in undertaking actions aimed at elimination of potential dangers that may occur during injection of water into absorbtive horizons. On the basis of the conclusions resulting from the research, a set of techniques and technologies was proposed that would allow the preparation of extracted reservoir waters for injection. Its guidelines in particular relate to the near-wellbore damage protection of injection well.

    Opis:
    W artykule zawarto ogólne informacje o początkach koncepcji zrównoważonego rozwoju gospodarczego i społecznego na świecie oraz o realizacji tej koncepcji w odniesieniu do przemysłu paliwowego. Przedstawiono także informacje o roli normy jakościowej w innowacji gospodarki Unii Europejskiej. W kolejnych częściach zaprezentowano wyniki podjętych dotychczas w UE działań dotyczących paliwa E10+. Przedstawiono przegląd przeprowadzonych badań, których wyniki posłużą do podjęcia odpowiednich decyzji co do dalszych prac nad specyfikacją paliwa E10+, prowadzonych w ramach Programu Horyzont 2020. Podsumowano także prace dotyczące paliwa E10+ prowadzone dotychczas w INiG – PIB.
    This article provides general information about the origins of the concept of sustainable economic and social development in the world and the implementation of this concept in relation to the oil industry. Information on the role of quality standards in the innovation of the European Union economy is also presented. In the following parts, the article presents the results of actions taken so far in the European Union with regard to fuel E10+. It presents also an overview of research performed, the results of which will be used to take appropriate decisions regarding further work on the development of E10+ fuel specifications, under the Programme Horizon 2020. A summary of research work carried out so far in the Oil and Gas Institute – National Research Institute in the field of the E10+ fuel is also presented.

    Opis:
    The main goal of European Green Deal is for all EU member states to become climate-neutral by 2050. One option is CO2 sequestration. It means underground CO2 storage in geological structures. Theoretically, such sequestration could lower CO2 emissions by about 20%. This process has also, however, a number of disadvantages, such as high costs and restricted volume of appropriate geological objects. Sequestration processes can be divided into three groups: sequestration in depleted hydrocarbon deposits, sequestration in aquifers and sequestration coupled with EOR and geothermal energy capture. To sequestrate a significant part of emitted CO2, it is necessary to separate CO2 in power plants, to adapt appropriate geological objects, to investigate such objects and to build infrastructure and pipelines. What elements affect the cost of sequestration? First of all, separation of CO2 requiring large amount of energy (about 10% of energy produced in power plant). Next, gas must be compressed and rendered to supercritical/liquid phase. In the case of depleted hydrocarbon reservoirs, we know that the structure is tight and there is an infrastructure on the surface. When it comes to aquifers, it is necessary to carry out a full set of investigations, drill holes and build an infrastructure. If Poland wants to fulfill all tasks of Green Deal, huge investments are needed. The cost analysis should take into account such elements as the length of pipelines to be constructed and existing power grids. Any probable sequestration must be correlated with hydrogen projects. RES cannot work alone because they are not able to provide a constant supply of energy. It can be achieved with energy mix. Such a mix should be based on nuclear plants built in place of the greatest coal plants, which will make it possible to use the existing power grids. RES coupled with hydrogen economy should result in the second largest contribution to energy mix. All coal power plants must be modernized. Hybridization must be taken into account here (biomass or steam and gas power plants). This should reduce their emissions by about 30–40%. The share of sequestration will be very small and associated with geothermal energy.
