Possible resources in these formations include about 345 billion barrels of world shale oil and 7,299 Tcf (trillion cubic feet) of world shale gas (Fig. 1) [1–3]. Furthermore over 85% of global resources of shale gas and over 72% of tight gas are located within fifteen countries. Despite the downturn in the global markets, unconventional natural gas production increased recently. Exploitation of main shale oil and gas basins is still more popular due to the higher reservoir potential and economically feasible drilling and exploitation [4–6]. Due to the energy policy implemented by the Polish government and the downturn in the global oil and gas industry, the situation in the Polish gas market has significantly changed in last few years. According to Polish Geological Survey reports, the number of granted concessions for exploration and exploitation remarkably diminished from January 2012 with only 30 concessions now active. For a better understanding of the current situation in Poland, 115 concessions were active in 2012 and 40 in 2015 [7–10]. However, amongst European countries Poland still has one of the most significant potentials for shale gas exploitation. Poland is in thirteenth position in the world and the first in Europe with the largest resources of shale gas. Given favorable conditions and market trends in the oil and gas industry, Poland could be a leader in the production of shale gas in the mid and long term future due its high-developed scientific and technical experience. The reported Polish shale gas resources could potentially cover demand for natural gas in the region of Central Europe [4].","PeriodicalId":201856,"journal":{"name":"AGH Drilling,Oil,Gas","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125742082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most frequently it is realized with large-diameter dewatering wells which have been mostly drilled with the invert mud rotary method and airlift. This method allows for quick drilling in lithologically diversifi ed aquifers, minimizing the negative impact of mud on the near-well zone. When drilling in dewatered carbonate rocks with the stone runs or well developed karst the effi ciency of this method considerably decreases. The technical and technological aspects of use of downhole ham- mers for drilling large-diameter dewatering wells in diffi cult geological conditions are discussed in the paper. Thanks to the use of this method for drilling wells in ‘Bełchatów’ Lignite Mine the drilling rate could be increased and the number of complications and drilling failures lowered. of natural temperature profi le in aborehole heat exchanger (logger NIMO-T), – thermal response test. The problem of eliminating natural gas microfl ows through the cement slurry while bonding has been investigated by scientists in a number of scientifi c and research centers. Works have been undertaken to defi ne the causes of gas migration and predict possibilities of interchannel communication in the hardened cement slurry. In the course of bonding cement slurry changes its state from liquid through gel to solid. Accordingly, the gas migration eff ects should be taken into account in the formation of these phases. The results of tests of gas migration in the course of binding and building structural strength have been presented in this paper. Both research methods have been compared and a high dependence of parameters defi ned by each of them has been found. The research works were conducted with the use of innovative apparatuses thanks to which the phenomena taking place in the course of binding can be observed. This gives the possibility of working out recipes of sealing slurries applicable to deposits where the risk of occurrence of gas migration is high. Cement sheath serves primarily as a zonal isolation for the life of the well while protecting and supporting the casing. Nowadays, more and more solutions in the term of diff erent cement slurries compositions appear on the market. One of them is application of fl uid ashes as an alternative substitution of cement itself. The purpose of it is to overcome a challenging environment where a high concentration of corrosive gases or fl uids exist. An example of that aggressive substance is carbon dioxide. Moreover, this is how it might reduce the cost of the cementing process. Laboratory research was conducted at the Drilling, Oil and Gas Faculty and Materials Science and Ceramics Faculty at AGH University of Science and Technology in Krakow.
