Item type:Article, Access status: Open Access , The multicriteria method for selecting rigs for drilling gas wells from post-mining gobs(Wydawnictwa AGH, 2017) Macuda, Jan; Łukańko, Łukasz; Hendel, JacekDuring drilling wellbores from the surface to recover methane from post-extraction gobs, attention should be paid to using appropriate rigs. Rigs with optimum technological parameters, adjusted to the geological setting, design of wellbore and technology of drilling, allow for high drilling rates and a considerably lower cost of realization to be obtained. The rig to be used for drilling production wells can be correctly selected using the multicriteria optimization method with synthetic evaluation measure of its technological parameters. For this purpose, the technological parameters of rigs available on the Polish market for the realization of normal diameter wells with percussion-rotary method to a depth of 500 m and 1000 m were reviewed. Taking into account the geological build of the Upper Silesian area and the design of the producing well used for the production of methane from past-extraction gobs, eight evaluation criteria and their weights (W) were selected. On this basis the technical parameters of rigs to be used for drilling wells to a depth of 500 m and 1000 m were reviewed with the multicriteria method. This created the basis for selecting dedicated rigs with optimum technological parameters for drilling normal diameter wells to a depth of 500 m and 1000 m.Item type:Article, Access status: Open Access , Analysis of the acoustic climate during the drilling of gas wells in post-mining areas(Wydawnictwa AGH, 2017) Macuda, Jan; Łukańko, Łukasz; Hendel, JacekCoal mine methane from post extraction coal gobs is most efficiently produced with drilling wells realized from the surface. In Polish conditions, such wells are most frequently drilled in highly urbanized areas and residential quarters. The drilling of such wells creates the hazard of exceeding admissible noise levels in the areas requiring acoustic protection during the day and night. Therefore it is very important to assess the level of noise emitted by the rig and to establish the isophones 45 dB and 55 dB for various field conditions. With such information, the location of the rig can be properly selected at the stage of well design. The level of noise emitted in the environment during the drilling of experimental gas well Wieczorek-AGH-1, was established on the basis of noise analyses performed within the well pad area and its closest vicinity with the reference method, described in the Regulation of the Environment Minister of 30 October 2014 concerning the requirements of the analyses of emissions and the quantity of water consumption (Official Journal of 2014, item 1542), hereinafter called the Regulation.Item type:Article, Access status: Open Access , Demand for heat from rock mass and borehole heat exchangers for a ventilation system in case of the auditorium at the Faculty of Drilling, Oil and Gas at AGH UST in Krakow(2016) Hendel, Jacek; Śliwa, Tomasz; Gonet, Andrzej; Łuczak, Rafał; Gałuszka, Łukasz; Kowalczyk, JoannaWhile calculating the heat demand for a ventilation system, the average monthly dry-bulb temperature is taken as the external temperature. While analysing a facility for public use, dedicated for 150 people and possessing a large share of transparent external walls it was shown, that using an hourly temperature in calculations, the obtained total energy demand (i.e. for heating and air conditioning) is 22% higher than the result obtained while taking into account an average monthly temperature. The obtained result points out the necessity of an individual approach to any large room, taking into consideration a temperature in a period of time significantly shorter than one month.Item type:Article, Access status: Open Access , Technical and economic issues of offshore pipeline carbon dioxide transportation(2014) Włodek, Tomasz; Kuczyński, Szymon; Hendel, JacekThe technical and economic conditions of carbon dioxide offshore pipeline transportation are presented in this paper. The basie conditions in which carbon dioxide will be transported, as well as the thermodynamic conditions, physicochemical properties and technical parameters, relevant to $CO_2$ pipeline transport, are addressed in this article. The basie costs of pipeline carbon dioxide transport are also considered. The carbon dioxide flow was simulated for a few pipeline diameter sizes to determine the operating pressure of the pipeline for various maximum mass flow rate values. Different conditions of $CO_2$ flow including impact of ambient conditions were analyzed. There is also included an analysis of technological systems and installation concepts for carbon dioxide preparation for efficient pipeline transportation.Item type:Article, Access status: Open Access , An overview of coal bed methane potential in Polish coal basins(2013) Cieślak, Katarzyna; Hendel, Jacek; Kuczyński, SzymonCoal bed methane (CBM) may become an important source of energy in Upper Silesian Coal Basin. Coal bed methane in Poland occurs within three coal basins of which the best recognized and most promising is the Upper Silesian Coal Basin. Approximately 80.1% of proved balance of coal deposits resources in Poland occurs in the Upper Silesian Coal Basin, where 50 fields are operated by 28 mines. Thus, since early 90s of the 20th century the USCB is attractive for foreign companies which perform evaluation of coal bed methane obtaining possibility as main fossil. However, all previous attempts to commercial production of CBM did not bring expected results, but they constitute extensive information database for current and future research towards CBM exploitation. Prognostic resources of coal bed methane in USCB are estimated to 107 bln m$^{3}$. Recoverable balance resources are estimated to 87.6 bln m$^{3}$. Much smaller perspectives are related to the poorly identified regions of Lublin Coal Basin and Lower Silesian Coal Basin. It is estimated that balance resources of hard coal in LCB, represents approximately 19.2% of Polish hard coal balance resources.Item type:Article, Access status: Open Access , Magazynowanie w górotworze ciepła pochodzącego z różnych źródeł(2012) Gonet, Andrzej; Śliwa, Tomasz; Hendel, JacekW artykule przedstawiono najbardziej popularne metody magazynowania energii w górotworze. Scharakteryzowano magazyny wykorzystujące otworowe wymienniki ciepła (BTES - Borehole Thermal Energy Storage) lub warstwy zawodnione (ATES - Aquifer Thermal Energy Storage). Wskazano liczne źródła zbędnej energii odpadowej w zakładach przemysłowych. Pokrótce opisano doświadczenia krajów pionierskich w dziedzinie technologii UTES (Underground Thermal Energy Storage). Autorzy udowodnili konieczność magazynowania energii, wskazali korzyści i bezpieczeństwo układów UTES oraz przedstawili jak wydział Wiertnictwa, Nafty i Gazu AGH włączył się w proces lepszego poznania i opisania zjawisk towarzyszących procesowi magazynowania energii w górotworze i jego efektywności.
