Air injection techniques (high pressure air injection and in-situ combustion) for enhanced oil recovery (EOR) have attracted extensive attention due to its low cost. Air injection can be applied in many candidate reservoirs including carbonate reservoirs that account for a great proportion of total oil reserves all over the world. Dolomite and calcite are the main minerals of carbonate reservoirs. Therefore, it is necessary to study their effect on the oxidation of crude oil as the oxidation reaction exactly occur...

Currently applied groundwater protection against penetration of pollutants from landfills are membranes that isolate the layer of stored waste from the substrate. As the material most commonly used are materials such as loam and natural clay or composite materials, such as plastic films or asphalt. Also there are known methods of using waste materials such as fly ash, as well as silicate-ash composites for the manufacture of seals in civil and hydraulic engineering. Literature also contains descriptions of the res...
