Opis:
Shifts in populations and economic structure are as old as population settlements themselves. As technologies change and economies adapt, regional comparative advantages also evolve. Among the most consequential of recently developed new technologies is horizontal drilling, which has opened vast regions of the world to the extraction, development,and use of low-cost energy from shale gas. Economic transitions and structural change are inevitable. The challenge for regional economists, policymakers, and economic developers lies in the identifying and managing these transitions in ways that maximize benefits and minimize the costs that accompany them. Complicating this challenge is the recognition that the geographic distributions of costs and benefits of economic development often do not coincide. This spatial mismatch of costs and benefits has been prominent historically in regional resource boom and bust cycles, many of which have been fed specifically by energy resources. The resources of energy rich regions have often been exploited in ways that provide short- term regional economic benefits and disruption, longer-term economic development often accompanied by environmental and physical infrastructural degradation. Recognizing that we are entering the early stages of one of the most substantial resource based shifts in economic structure in the history of energy resource development, we have the opportunity and the obligation to learn from successes and failures ofprevious economic transition management efforts, and to design strategies that will maximize the benefits and minimize the negative consequences of shale gas development. This contribution identifies and elaborates upon four critical dimensions of the transition management challenge. The first dimension includes the economic and environmental aspects of the extraction activities including drilling, materials assembly and usage including employment, income, capital equipment, and consumables, both manufactured and natural. The second dimension identifies the negative externalities of impacts on off-site physical infrastructure, with a special emphasis on transport infrastructure. In attempting to minimize negative consequences, programs should be developed to leave affected areas no worse off, at worst, and better off if possible. The road network involved in support drilling can extend well beyond the obvious transport arteries, even to jurisdictions that are not direct beneficiaries of severance taxes or impacts fees. The third dimension centers on economic structural changes related to upstream and downstream activities in the production and supply chains, and the fourth dimension concerns the roles of and impacts upon social and institutional structures.

“Together about shale gas”
Opis:
This paper discusses the basic assumptions of Technology Assessment (TA). As an example of TA process the author employs “Together about shale gas” programme (executed in northern Poland). The first two sections briefly outline the Polish context of shale gas extraction and describe what technology assessment is. In the next two chapters the objectives and outline of ‘Together about shale gas’ programme are presented. The author attempts to recognize how many of the TA assumptions are given in the programme and identify its outcomes. The final section examines challenges for the Polish policymakers in the field of technology assessment.

Opis:
Hydraulic fracturing has been practiced for over thirty years to improve effective porosity and stimulate oil and gas production. In the Appalachian Basin it has been used with horizontal drilling since 2008 to extract methane and natural gas liquids from source rock such as the Marcellus Formation. Hydraulic fracturing generates large volumes of waste water known as flowback: about 3,800 m3/well. Literature regarding the chemical composition of this waste stream is limited. This study examined injected hydraulic fracturing fluid from two wells and flow- back from four hydraulically fractured wells. Wells were sampled at various times during the flowback cycle and in sections of the basin known to produce either wet or dry gas, the former producing higher volumes of natural gas liquids. Concentrations were compared to available literature values and to drinking water standards as a basis for determining which parameters might compromise nearby, domestic wells in the event of an accidental release. Measured parameters included three classes: organic, inorganic ions and radioactive isotopes. Concentrations of all three classes of contaminants tended to increase during the flowback cycle. Organic contaminants including BTEX were substantially higher in the wet gas well. Radioactive isotopes, particularly alpha, beta, radium 226 and radium 228 increased during flowback. All contaminants were found in much higher concentrations in flowback water than in injected hydraulic fracturing fluids suggesting that the bulk of contaminants originate in the Marcellus formation rather than in the injected hydraulic fracturing fluids. Primary and secondary drinking water standards for all classes of contaminants were generally exceeded in flowback water. In addition to summarizing the chemical composition of flowback water, the presentation recommends practices for controlling the risk of environmental exposure.

Clay shale rocks large intervals drilling generates a serious issues caused by hydration, swelling and dispersion of clay rock. Those reactions might lead to break-downs and complications in drilling as the consequences of borehole wall stability loss that have source in cave effect (occurrence of caverns and cavings) and borehole diameter sharp decreasing. Therefore, the outcomes of the research that have been undertaken are muds formulas adjusted for drilling various clay rock intervals.

Opis:
Poland, due to the estimated shale gas deposits amounting to 346–768 billion m3 has become one of the most attractive regions for shale gas exploration in Europe. Throughout the period 2010–2015, 72 exploratory drillings were made (as of 4.01.2016), while hydraulic fracturing was carried out 25 times. Employing new drilling and shale gas prospecting technologies raises a question pertaining to their impact on the environment. The number of chemical compounds used (approximately 2000) for the production of new technological fluids may potentially pollute the environment. The fact that the composition of these fluids remains undisclosed hinders the assessment of their impact on the environment and devising optimal methods for managing this type of waste. The presented work indicates the chemical compounds which may infiltrate to groundwater, identified on the basis of technological fluids characteristics, as well as the review of studies pertaining to their impact on potable water carried out in the United States. The study focused on marking heavy metals, calcium, sodium, magnesium, potassium, chlorides and sulphates in the surface waters collected in proximity of Lewino well.

Opis:
Shale gas is one of the well-known unconventional resources of natural gas all over the world. This term refers to natural gas that is trapped within shale formations. Shales are fine – grained sedimentary rocks which can be reach resources of both petroleum and natural gas. This sedimentary rocks are heavily layered and in their nature exhibit VTI velocity anisotropy behavior (Van Dok et al. 2011). This statement indicates that the world among us is not isotropic and we should not neglect this fact in our geophysical research. Anisotropy, in general is the property of the material. It can be described as the attribute of a material’s property with respect to the direction in which it is measured (Pereira & Jones 2010). There are two essential types of anisotropy: VTI and HTI. Vertical velocity layering gives rise to VTI (vertical transverse isotropy) velocity in which seismic wave velocity is faster in the horizontal direction than in the vertical one. The second type of isotropy is horizontal transverse isotropy (HTI) which causes azimuthal traveltime variations. The common mechanism for this type of anisotropy is vertical aligned fractures in an isotropic background medium (Jenner 2011.) Authors of this study focused mostly on VTI as this type of anisotropy is present in shale formations, as a result of small scaled heterogeneities from fine layering (Thomsen 1986). The VTI anisotropy can be mathematically described by using three Thomsen parameters: epsilon, delta and gamma. Epsilon is a measure of the difference between the horizontal and vertical propagation velocities for compressional waves. Gamma parameter is a measure of the difference in the horizontal and vertical propagation velocities for horizontally polarized shear waves (SH waves). Delta parameter is not easily described either mathematically or qualitatively (Pereira & Jones 2010), but it influences the anisotropy velocities in medium incidence angles. These parameters can be mathematically expressed by equations proposed by Leon Thomsen (Thomsen 1986). In this study, authors present influence of VTI anisotropy on microseismic data recorded during hydraulic fracturing of shale intervals in one of the well located in Northern Poland. Authors points out how the anisotropy affects on microseismic events location, locating them in isotropic and anisotropic velocity models with usage of TGS algorithm. Furthermore, authors indicate possible solution to estimate VTI parameters based on microseismic data. VTI anisotropy parameters plays critical role not only in case of microseismic data analysis but also in processing of active seismic data. Authors proved that VTI anisotropy present in the investigated area has strong influence on microseismic events location especially in depth. Moreover estimation of VTI anisotropy parameters based on microseismic data with usage of Thomsen equations is possible.

Opis:
The recent boom in shale gas exploration around the world has sparked a paradigm shift in energy security in many countries in the world. With the successful exploration of shale gas production in the United State’s, many operators are trying to replicate the success in other parts of the world specifically in European countries where the presence of organic rich shale deposits have signaled a promising investment for the recovery of shale gas. Perspective studies for the Polish shale gas field in Poland have been ongoing. One part of this project is the comparison of hydraulic fracture thickness between the U.S shale gas field and Polish for better and effective design and modeling of reservoirs for the optimal exploration and recovery of shale gas. Successful production of natural gas from Polish basins requires a hydraulic fracture stimulation to unlock the gas trapped in the shales coupled with a geologic analysis of the shale rocks.

American energy revolution
Opis:
With a unique mix of innovation, entrepreneurship and favorable economic conditions, the United States has become the world's largest producer of crude oil and natural gas, and in the near future may become a key exporter of these commodities. Of course, this would not be possible if there were no huge resources in the American territory. However, advanced technology has enabled them to operate. The boom on unconventional raw materials, or rather raw materials extracted by unconventional methods, is so far an American specialty. Although many states have tried, and some continue to do so, no one has succeeded in repeating the success of American entrepreneurs. This work consists of three essential parts. The first concerns issues related to types of unconventional natural gas resources. The second involves the shale revolution in the United States. The third refers to the selected economic aspects of this revolution. The main thesis is that the experiences of the American Revolution are very difficult to replicate in other regions of the world. Due to the specifics of the US mining industry, the deregulated energy market and American legal solutions, it is difficult to expect a repeat of success.

Opis:
Shale gas in the United States over the past decade, and interest has spread to potential gas shales in Canada, Europe, Asia, and Australia. One analyst expects shale gas to supply as much as half the natural gas production in North America by 2020. Carbon dioxide capture and storage (CCS) is a set of technologies for the capture of CO2 from its anthropogenic point sources, its transport to a storage location, and its geosequestration. This is only one, though very important, option in a portfolio of actions to fight the increase of atmospheric CO2 concentration and to mitigate climate change, while at the same time allowing for the continued use of fossil fuels. Deployment of CCS technologies is expected to be limited in the next 5-10 years, but to contribute significantly to the reduction of CO2 emissions 20 years from now. Capture of CO2 using existing separation techniques can be applied to large point sources, i.e. power plants or industrial plants; CO2 can be easily transported over large distances using pipelines and ships; finally CO2 can be permanently stored in suitable deep geological formations, namely deep saline aquifers, oil or gas reservoirs, and unmineable coal seams, or it can be fixed in carbonates. The paper deals with the innovative method of carbon dioxide storage coupled with gas shale fracturing and methane recovery developed in the Military University of Technology. It allows to effectively mine the shale gas and to store carbon dioxide in shale rock. It must be noticed that CO2 pollution is a very important problem in Poland, because of European Union CO2 limits. Also carbon dioxide thermodynamic process of decompression numerical calculation, which simulates the injection of the cold liquid gas into the shale formation (high temperature and pressure conditions) and its influence on shale rock fracturing as well as initial experimental verification of the method was presented in the paper.

Opis:
The Polish part of the Baltic region is located within the contact zone between two large geological units: the Precambrian platform and the Paleozoic platform. It comprises the Polish sector of the southern Baltic Sea and the adjacent onshore part of Northern Poland (Western and Eastern Pomerania). The fundamental geological pattern is defined by the Teisseyre-Tornquist Zone, separating the East European Craton from the Paleozoic platform. As a result of exploration activity in the onshore Pomerania region, four oil fields in Cambrian sandstones, seven gas fields in Carboniferous sandstones, six gas fields in Rotliegend sandstones, and eleven oil fields within the Zechstein Main Dolomite horizon have been discovered. The petroleum play of the southern Baltic Sea region and adjacent areas must be considered separately for Eastern and Western Pomerania. In the Peribaltic Syneclise we can only take into consideration organic matter appearing in lower Paleozoic rocks but their geothermal history refers to the period from the Vendian up to the recent. The present extent of the "oil window" in the Upper Cambrian rocks is mainly restricted to the offshore area. Reservoir properties of the "gas window" Cambrian rocks are rather low due to intensive diagenetic processes. Acquisition of gas should be possible by processes of hydraulic stimulation (tight gas). Lower Paleozoic rocks rich in organic matter (Ordovician and Silurian), especially in the border zone of the EEC (Ro >>gt; 1.3%), could be an area of unconventional gas fields (shale gas). The Western Pomerania petroleum play shows two separate source rocks units. The older one embraces Carboniferous deposits with organic matter of terrestrial origin and generated gases accumulated in the Rotliegend and Carboniferous traps. The second petroleum system is located within the carbonates of the Zechstein Main Dolomite (Ca2). This is a closed system, meaning that the source rocks are at the same time the reservoirs sealed by Zechstein evaporates. Hitherto discovered hydrocarbon deposits in the Polish part of the Baltic region have confirmed good perspectives regarding oil and gas hydrocarbon zones. New, conventional and unconventional discoveries remain possible.

Opis:
Shales are the most abundant sedimentary rocks. The shales with high organic content are considered good source rocks for oil and gas accumulations. From the engineering standpoint, shale gas reservoirs exhibit characteristics of both conventional gas reservoirs (free gas in pore space) and coalbed gas reservoirs (adsorbed gas). Their extremely low matrix permeability (order of nanodarcies, nd) creates additional complexity in their development. On the other hand, the abundance of shales makes this type of unconventional gas development very attractive for economies that seek relatively clean sources of energy. The paper reviews four general steps in the development of shale gas reservoir: geological identification of potentially productive gas shales, engineering characterization of gas shale reservoirs, typical completion techniques proven successful in shales, evaluation of reserves and development planning. The review focuses on the issues which in the author's opinion have major impact on successful shale reservoir development. The review is based on experiences of the independent oil and gas producer successfully engaged in shale gas development in the continental USA.
Iłołupki należą do najbardziej obfitych skał osadowych. Ze swoją wysoką zawartością substancji organicznych stanowią znakomitą skałę macierzystą dla akumulacji ropy naftowej i gazu ziemnego. Z inżynieryjnego punktu widzenia gaz pochodzenia iłołupkowego łączy cechy tradycyjnego złoża gazu (wolne przestrzenie porowe) z gazem pochodzącym ze złóż węgla (gaz zaadsorbowany). Niezwykle niska przepuszczalność matrycy (rzędu nanodarcy, nd) stwarza dodatkowy problem przy wydobyciu. Z drugiej strony, obfitość iłołupków zachęca do eksploatacji tego niekonwencjonalnego gazu, szczególnie w przypadku gospodarki nastawionej na stosunkowo czyste źródła energii. W artykule dokonano przeglądu czterech głównych etapów udostępnienia złóż gazu pochodzącego z warstw iłołupków: geologiczna identyfikacja warstw iłołupków zawierających gaz, charakterystyka inżynierska złóż gazu z warstw iłołupkowych, sprawdzone techniki udostępniania w warstwach iłołupków, oszacowanie zasobów i opracowanie planu udostępnienie. W artykule skupiono uwagę na sprawach, które w opinii autora mają podstawowe znaczenie w udanym procesie udostępniania złóż w warstwach iłołupków. Przedstawione omówienie oparto na doświadczeniach niezależnego producenta ropy naftowej i gazu ziemnego, który z powodzeniem zaangażował się w udostępnianie gazu ziemnego z warstw iłołupków na lądowej części USA.

The innovative method of shale gas recovery with the use of subcritical CO2 is currently developed within the project titled “Development of guidelines for design of innovative technology of shale gas recovery with the use of liquid CO2 on the base of numerical and experimental research – DIOX4SHELL ”, supported by the National Centre for Research and Development (NCBR). The project is carried out by Polish company PGNiG and by academics from WAT, AGH and PW (Military University of Technology, AGH University of Science and Technology, and Warsaw University of Technology). Finding the best business model, in which costs of CO2 production or acquisition are negligible is one of the most important factors influencing the economical effectiveness of the technology. The main part of known CO2 acquisition methods is based on fuel purchase and its combustion, what is very expensive process. It results with the high CO2 price, when purchasing from producer, about 300 zl/ton. This price is quite high, considering current low prices of natural gas. In the paper basic aspects of CO2 acquisition from CO2 producers, exhaust gases treatment plants or plasma gasification methods will be presented.

Opis:
There are many types of natural gas fields including shale formations which are common especially in the St-Lawrence Valley (Canada). Since methane (CH4), the major component of shale gas, is odorless, colorless and highly flammable, in addition of being a greenhouse gas, methane emanations and/or leaks are important to consider for both safety and environmental reasons. On this regard, passive remote sensing represents an interesting approach since it allows characterization of large areas from a safe location. In order to illustrate the potential of passive thermal infrared hyperspectral imaging for research on natural gas, imaging was carried out on a shale gas leak that unexpectedly happened during a geological survey near Hospital Enfant-Jesus (Québec City, Canada) in December 2016. Quantitative methane imaging was carried out based on its unique infrared spectral signature. The results show how this novel technique could be used for advanced research on shale gases.

Opis:
Shale gas is natural gas produced from shale, a type of sedimentary rock. Shale gas has become an increasingly important source of natural gas in the United States over the past decade, and interest has spread to potential gas shales in Canada, Europe, Asia, and Australia. One analyst expects shale gas to supply as much as half the natural gas production in North America by 2020. As of 2010, Poland imports two-thirds of its natural gas from Russia. ConocoPhillips has announced plans to explore for shale gas in Poland, along with Lane energy. The recently made available US Department of Energy report revealed that the largest reserves of shale gas in Europe are in Poland. The authors of the report calculate that Poland has reserves of about 22.45 trillion cubic meters of shale gas, of which 5.30 trillion cubic meters is immediately available for extracting. The most common method of shale gas recovery is hydraulic fracturing - the propagation of fractures in a rock layer caused by the presence of a pressurized fluid. Hydraulic fractures form naturally, as in the case of veins or dikes, and is one means by which gas and petroleum from source rocks may migrate to reservoir rocks. This process is used to release petroleum, natural gas (including shale gas, tight gas and coal seam gas), or other substances for extraction, via a technique called induced hydraulic fracturing. The method is critically assessed by ecologists. The paper deals with new method of gas shale fracturing and gas recovery coupled with carbon dioxide storage. It allows to effectively mine the shale gas and to store carbon dioxide in shale rock. It must be noticed that CO2 pollution is a very important problem in Poland, because of European Union CO2 limits. Also the numerical calculation of carbon dioxide thermodynamical process of decompression process, which simulates the injection of the cold liquid gas into the shale formation (high temperature and pressure conditions) and its influence on shale rock fracturing will be presented.

Opis:
Unconventional gas by definition is economically less profitable and more difficult to extract then conventional gas. However, gradual depletion of conventional gas fields as well as large resources of unconventional gas make the latter an attractive target. Coalbed methane (CBM), tight gas and shale gas have been successfully developed in the US over the past two decades. Shale gas production has grown at the fastest pace in recent years and reached over 2 tcf in 2008, which is 6-fold increase since 1998. Key to success of unconventional gas development was Noncoventional Fuels Tax Credit introduced by the US government in 1980. This initial production growth of unconventional gas and shale gas in particular, was later sustained by the development of horizontal drilling and fracture stimulation technologies, economy of scale and increasing gas prices. Economics of producing shale gas is marked by bigger resource potential and, at the same time, lower production rates and higher drilling costs as compared to conventional gas, which entails adopting cautious investment strategies. Shale gas exploration strategies are also different from those of conventional gas and, initially, require an extensive source rock analysis and a big land position to identify "sweet spots". Shale gas exploration in Poland is in its infancy, being focused on the Silurian-Ordovician shale formation which is poorly explored and thus poses a significant exploration risk. Therefore, exploration companies have used a cautious approach which is reflected in planning of the concession activities divided in a few phases, with each successive phase contingent on the positive results of the preceding one. These phases include: existing data analysis, seismic, drilling an exploratory well with extensive core analyses prior to a pilot testing program using horizontal wells. On a technical level of shale gas exploration, the integration of many disciplines is required for commercial success. Potential barriers to shale gas exploration in Poland have been identified such as: regulations which are in favor of the domestic service companies impeding competition, changeable and unclear environmental protection regulations, as well as insufficient liberalization of the domestic gas market.
