The accelerated development of shale gas is accompanied by growing public concern regarding the safety of shale gas extraction and its impact on human health and the environment. For the US, shale gas exploitation proved very successful in changing the energy landscape in terms of security of domestic supply and increased contribution of gas in the energy mix. For Europe, shale gas exploitation could increase our resources and production of natural gas; a critical fuel for the transition to a low carbon energy system. However, there are a number of important gaps in our present understanding of shale gas exploration and exploitation, and a strong need for independent, science-based knowledge of its potential impacts in a European context. The M4ShaleGas program focuses on reviewing and improving existing best practices and innovative technologies for measuring, monitoring, mitigating and managing the environmental impact of shale gas exploration and exploitation in Europe. The technical and social research activities will yield integrated scientific recommendations for 1) how to minimize environmental risks to the subsurface, surface and atmosphere, 2) propose risk reduction and mitigation measures and 3) how to address the public attitude towards shale gas development. The 18 research institutes from 10 European Union Member States that collaborate in the M4ShaleGas consortium cover different geopolitical regions in Europe, including Member States that are at the forefront regarding shale gas exploration and exploitation in Europe as well as Member States where shale gas exploitation is not yet being actively pursued. The project governance ensures proper integration of all research activities. Knowledge and experience on best practices is imbedded by direct collaboration with US and Canadian research partners and input from representatives from the industry. During the project, results will be public and actively disseminated to all stakeholders.

In this study some of the experimental results of water shut-off treatments in oil and gas production wells were presented. The effect of water saturation of Miocene rocks of the Carpathian Foredeep on the relative permeability to gas was analyzed. Also, wide review of the worldwide publications from the point of view of the results obtained in water shut-off treatments in oil and gas formation was presented. Based on experimental results efficiency of relative permeability modification of sandstone from Szydłowiec to brine and nitrogen by four selected chemicals polymers and microgels was evaluated. Experimental results indicated that trend changes of permeability modification strongly depends on the fluid used in the RPM treatment. Moreover, efficiency of permeability modification to brine depends on flow rate of brine through the core - the lower brine flowrate the higher efficiency of the RPM treatment. RPM product number 1 caused significant loss of permeability to brine ca. 60% and slight permeability modification to gas ca. 18%. This permeability change to brine and gas was obtained by modification of formation wettability what affects well productivity. In the case of product number 2 which is based on microgels technology, also significant modification of selective permeability to brine was observed. Loss of permeability to brine was in the range of 65 to 90% while to gas ca. 50%.


Com. fatly acid Me ester (FAME) was added to com. gas oil and used for driving the Diesel engine equipped with modern common rail-type fuel injection system operated under std. conditions. Engine output torque, exhaust gas quality (particulate matter) and changes of quality of lubricating oils (viscosity, acid no., oxidn. stability) were detd. Applicability and limitations of FAME addn. to the gas oil were evaluated. No substantial contraindications were given.


Emissions of CO2 from alk. and supercrit. transesterification of palm oil with MeOH to biodiesel were compared by using literature data (C. Kiwjaroun at all., 2009). The emission from supercrit. process was much higher than that from the alk. one.


EtOH, BuOH and EtMeCHOH were added (up to 15% by vol.) to a com. Pb-free hydrocarbon gasoline (octane no. 95) to study their effect on std. distn. curves and vapor pressure. The addn. of EtOH resulted in an increase while the addn. of butanols in a decrease in the vapour pressure of the gasoline. Only small changes on distn. curves were obsd.


Com. Ca dinonylnaphthalenesulfonate and an ethylene oxide and propylene oxide copolymer were added (0.001-0.010% by mass) as demulsifiers to Zn dialkyldithiophos-phate-contg. hydraulic oils with varying hydrocarbon compns. High demulsifying efficiency of both additives was obsd. even at their low concns.

Three organometallic combustion modifiers were prepd. and compared with a com. Fe one in respect to their catalytic activity in combustion of soot. The Fe-Co modifier was more efficient than the com. one.

Seeds, wood, straw and fermentation residues were studied for combustion enthalpy, chem. compn. and DTA curves and recommended as solid fuel components. For comparison, peat and bituminous coal samples were also studied.

European Union member states are obliged to identify and document geological formations and structures suitable for storage of CO2 from large industrial emitters in their territories. In Poland such studies were concentrated on deep saline aquifer formations in several regions of the country. Poland is one of a few countries already having some experience in CO2 storage in geological structures thanks to the first industrial installation sequestering acid gas by direct injection to aquifer underlying Borzecin natural gas field, in continuous operation since 1996. PGE Belchatów Power Plant is the largest conventional power plant in Europe. It annually consumes 35 million tons of brown coal and it is also a significant CO2 emitter. In the area of Bełchatów there is documented a number of deep geological structures that meet sequestration site criteria, particularly criteria concerning depth at which the structures are located, thickness, water mineralization and other petrophysical parameters. The paper presents mineralization maps of saline aquifers from selected stratigraphie horizons (Triassic, Jurassic), basic data characterizing the reservoir conditions in selected saline structures, as well as chemical composition of their brines and mineralization and physical parameters determined in the PVT laboratory. Authors describe mechanisms that determine the amount of CO2 that can be deposited in these aquifers. Research apparatus and procedures used during PVT study of reservoir brines and CO 2 mixtures are presented in the paper. The solubility of CO 2 in brines of the Belchatów region at pressures and temperatures corresponding to appropriate reservoir conditions were examined and reported in the paper.


Within a frame of the research project on Rotliegend tight gas, a data base comprising 760 full sets of reservoir and permeability parameters was created. Data from 55 wells were collected from interval of 1650-5003 m. The obtained results showed presence of clastic reservoirs sufficient for formation of "tight gas" type deposits in each of the analyzed wells. In most of the wells, reservoir rock series with non-zero permeability were detected. Parameters of pore space suggest the major role of compaction processes in pore space evolution, except for some areas where cementation processes were predominating. A high-permeability anomaly characterizing a separate group of eolian sandstones from the depths of over 40000 m anomaly may be explained as due to presence of pseudo- and micro-fractures.
