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.

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:
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.

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.

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:
With the International Energy Agency (IEA) projecting that the global demand for natural gas to increase by 50% from 2010 to 2035, the exploration of unconventional gas reserves (e.g. shale gas, tight gas and coal bed methane) will gain increasing importance as conventional gas reserves become more depleted. To enhance the production of unconventional gas and oil, water-based fracturing fluids are extensively used for the stimulation of North American shale plays because they are inexpensive and offer excellent proppant transport into the fracture when used with gelled polymers. However, in circumstances where water-based fracturing fluids are unsuitable due to concerns related to water sensitivity and clay swelling, alternative fracturing fluids are used such as nitrogen and carbon dioxide treatments. Nitrogen and carbon dioxide fracturing fluids are particularly advantageous in depleted and shallow formations because they offer a non-damaging effect around the fracture, rapid cleanup of flowback fluid, and reduced water requirements compared to conventional water-based fracturing fluids. Much research has been published about water-based fracture treatments, therefore, this review paper considers the use of nitrogen and carbon dioxide fracturing fluids used for the stimulation of unconventional shale plays, mainly in North America. By analysing selected literatures studies, this review paper summarises the utilization of the various types of nitrogen and carbon dioxide treatments (i.e. straight gas, foam, energized, cryogenic liquids) across various shale plays such as the Montney play, the Devonian play, and the Marcellus play. The paper further identifies the major benefits and challenges of nitrogen and carbon dioxide treatments documented by well operators, which will facilitate knowledge transfer about the applicability of nitrogen and carbon dioxide fracturing fluids.

Opis:
Hydraulic fracturing treatments of shale gas reservoirs is pumping process in which millions of gallons of fracturing fluids mixed with proppant materials and thickening agents are pumped into the target shale formation. Fluids are used to create the fractures in the formation and to carry a propping agent which is deposited in the induced fractures to keep them from closing up. Type and percentage of chemical additives that used in a typical fracture treatment varies depending on the conditions of well being fractured. A series of chemical additives are selected to impart a predictable set of properties of the fluid, including viscosity, friction, formation-compatibility, and fluid-loss control. Each component in fracturing fluids serves a specific, engineered purpose and geological structure of rock. The properties of fracturing fluid are very important in the creation and propagation of the fracture. For suc-cessful stimulation fracturing fluid mustto have certain chemical and physical properties. Study of the properties fracturing fluids has ahuge role inthe processes of shale gas extraction. In scientific literature indicates that hydraulic fracturing fluid performance became a prevalent research topic in the late 1980s and the 1990s. The majority of literature pertaining to fracturing fluids related to their operational efficiency and classification. Some of the existing literature offer information regarding the basic chemical components present in most of these fluids. This paper will discuss types of fracturing fluids and it components that may be used for hydraulic fracturing. Comprehensive history of the evolution of hydraulic fracturing fluids in the oil and gas industry plays a significant part in research. This work summarizes requests for fracturing fluids. In addition, this paper shows effect of rock mechanical properties on fracturing fluid selection.

There is a several year experience concerning exploration and production of shale resources in the USA. First production wells started in 1996 (the history of hydraulic fracturing is even 40-50 years older), and last few years one can observe a huge impact on American economy and decreasing level of natural gas import. One can assume that the development will grow significantly and the USA will stay self-sufficient and can start exportation of hydrocarbons - especially LNG. The economy will decide about the share of the natural gas in energy mix - energy balance. In the paper there is a detailed discussion concerning economy of the shale exploration and production (i.e. the costs of drillings, services, geological conditions versus timings and schedule of production). Based on analyzed scope one can predict a stable progress in cost reduction (learning curves) linked with production of shale hydrocarbons.

Opis:
The successful development of shale gas requires a fundamental understanding of shales and that can be challenging because these rocks vary significantly. For recoverable shale gas resources assessment a broad range of geological, geochemical, geophysical and geomechanical data is required. Information about the variable lithologies, mineralogies, and kerogen content is vital to locate favorable intervals for gas production. Knowledge of the in-situ stresses and porosity of these intervals is essential for developing hydraulic fracturing strategies to recover the gas in place. Geomechanical properties of shales are important in terms of determination of the likelihood of fractures initiating and propagating in shale materials. Geomechanical properties of rock include: Poisson's Ratio, Total Minimum Horizontal Stress, Bulk, Young and Shear Modulus. These properties play significant role in developing shale assets. Having access to geomechanical data can assist engineers and geoscientists during geomechanical modeling, hydraulic fracture treatment design and in some cases during reservoir modeling in shale gas fields. This paper is intended to give characterization of geomechanical properties of shale rock. It then refers to a case study of Baltic Basin of shale gas in Poland, for discussing it geological condition and rock properties.

Gained experience and success in the United States tight gas sand reservoirs Piceance, Anadarko, Greater Green, Lobo fields confirmed the hidden potential of unconventional hydrocarbon resources. In some production and development areas called coal bed seam, shale gas and tight sand reservoirs without intensifying operations isn't possible to produce commercial gas volumes. Used practises and gained large experiences in the crude oil fields are commonly used in the shale and tight gas fields across the United States. Application of these technologies of stimulation methods like fracturing in Europe is at the very beginning. Pioneer investors are waiting in all Europe for the well testing results from the first dozen fractured shale gas and tight sand reservoirs. Test results could have significant influence on the future planned massive drilling campaign of exploration of the unconventional hydrocarbon resources

Hydraulic fracturing operations performed at the stage of gas prospection in shale formations are aimed at opening out gas residing in rock micropores. Large quantities of fracturing fluid, with physicochemical composition adjusted to their properties, are injected to the selected interval of a horizontal well. Finally, sand (proppant) is injected along with the fracturing fluid to support the newly formed fracture. The results of a computer simulation of noise emission generated by high pressure pumps during hydraulic fracturing operations, and the results of noise measurements during such work in the north of Poland are presented in the paper. The analysis of the obtained results revealed that the noise standards for day hours in the residential area localized ca. 320 m from the well pad was not exceeded for the hydraulic fracturing operations. The noise level in the night hours was considerably higher, therefore a respective sound berm should be construed.

Opis:
Od XIX wieku, kiedy po raz pierwszy wydobyto gaz ze skały łupkowej i stwierdzono jego zasoby, odwierty eksploatacyjne intensywnie poddawano opróbowaniom w celu stwierdzenia ich opłacalności i możliwości wydobywczych, głównie w zależności od stopnia zaawansowania technologicznego stosowanego sprzętu wiertniczego. Zwykle łupki charakteryzują się dość słabą przepuszczalnością, uniemożliwiającą przepływ wystarczających ilości płynu do otworu, tym samym nie stanowiąc przemysłowo opłacalnych źródeł gazu ziemnego. Z tego też powodu zarówno w Polsce jak i na świecie techniczne osiągnięcia w zakresie szczelinowania hydraulicznego doprowadziły do intensywnego rozwoju wydobycia gazu z łupków. W celu utrzymania niskich kosztów w miejscu wydobycia gazu z łupków ważne jest zachowanie niskich kosztów utrzymania sprzętu i zapewnienie optymalnych kosztów wiercenia. Należy zwrócić uwagę na podstawowy sprzęt wiertniczy, np. na górny napęd przewodu wiertniczego, automatyczne klucze, układy wyciągowe, pompy płuczkowe itp. Wydłużenie godzin pracy sprzętu powinno gwarantować nieprzerwane jego działanie do ok. 50 000 godzin bez potrzeby wykonywania prac związanych z utrzymaniem. Faktyczny czas potrzebny na wymianę zużytych części maszyn jest w sumie pomijany, przy zachowaniu niespotykanego dotąd poziomu bezpieczeństwa pracy, dzięki zastosowaniu zaawansowanych technik szybkiego zwalniania hydraulicznego. Hałas wytwarzany przez sprzęt, masa i rozmiar stopniowo zmniejszały się dzięki zastosowaniu zaawansowanych silników napędowych i przekładniowych elementów transmisyjnych. Nowe i innowacyjne konstrukcje pomp płuczkowych i głowic obrotowych przewodu wiertniczego umożliwiają zastosowanie ciśnienia do 7500 PSI. Elektronicznie sterowane automatyczne systemy wiercenia umożliwiają w pełni autonomiczne wiercenie z ciągłą, automatyczną kontrolą nacisku na świder. Podsumowując, przy zastosowaniu w pełni komponentowej technologii, całkowite koszty wiercenia spadają, umożliwiając wykonanie większej liczby otworów do produkcji gazu z łupków, co z kolei z roku na rok może zwiększać potencjał wydobywczy gazu ziemnego w Polsce i na świecie.
Since the 19th century when shale gas was first extracted as a resource, shale gas wells have ever since been extensively put to test of being economically viable or unworkable, primarily dependent on the level of technological sophistication of the drilling equipment involved. Shales ordinarily have insufficient permeability to allow significant fluid flow to a well bore, thus most shales are not commercial sources of natural gas, which is why technical advances in hydraulic fracturing (fracking) are the main cause for the shale gas boom in Poland and around the world. To keep the cost factor down at shale gas drilling sites, low drilling equipment maintenance cost are an important factor as well to keep shale gas drilling economical. Here, the focus has been on the main drilling equipment such as top-drives, roughnecks, drawworks, mud pumps, and rotary tables. Prolonged equipment operating hours guarantee operations of up to 50,000 hours continuously until maintenance work is required. Actual time needed to replace wear and tear machinery parts has overall become negligible at an unprecedented level of safety using sophisticated so called hydraulic quick release system techniques. Equipment noise, weight, and size have shrunk continuously by the use of advanced drive motors and gear driven transmission trains. New and innovative mud pump and top-drive designs allow high pressures of up to 7,500 PSI. Electronically controlled auto driller systems enable fully autonomous drilling operations with continuous, automatic weight-on-bit control. In conclusion, by utilizing these entire component technologies, overall drilling costs go down and make ever more shale gas drilling wells economically viable, which in return increases production potential of natural gas year by year in Poland and elsewhere.

Opis:
In Poland the perspective shale gas formations concentrate in the area of the Baltic Basin, Podlasie Depression and Lublin Basin. Their depth varies from slightly above 2,000 to 4,500 m, depending on the location. Accordingly, novel rigs of high hoisting capacity and installed power capacity of master motors have to be used for opening natural gas deposits with the use of directional wells. The operation of such systems creates an acoustic hazard for the environment, especially in the close vicinity to the rig. The results of noise analyses of a prospecting well for hydrocarbons from unconventional sources in the north of Poland performed with the use of a rig MASS 6000E are presentedin this paper. The noise analyses concentrated on the rig area among the direct noise sources and the neighborhood to show the influence of drilling operations on the acoustic environment. The obtained results revealed that the noise emission in the rig area can be limited by optimizing the localization and placement of particular objects and systems within the rig site. This also applies to the placement of the noise barriers on the border of the rig to limit the noise emission towards objects requiring protection.
