Prospects for the development of hydrate storage and transportation technology of methane gas
(2015) Pavlenko, Anatolìj Mihajlovič; Košlak, Ganna Volodimirìvna; Vitâz', Oleg Ûlìjovič; Rybicki, Czesław
The gas hydrate tecłmologies can be alternative to the traditional methods of the rational use of hydrocarbon gases. However the known constructions of apparatuses for the production of gas hydrates cannot satisfy the condition of their industrial use fully. Authors offer to carry out the high-quality contact of gas and water at formation of gas hydrate by jet apparatuses with a free falling jet. On their basis a technological chart is offered for realization of continuous cycle of production of gas hydrate. The aim is to develop technical solutions and process parameters of continuous production of gas hydrates, which would satisfy the requirements of industrial application.
Compressed air energy storage as backup generation capacity combined with wind energy sector in Poland - implementation possibilities
(2015) Kuczyński, Szymon; Skokowski, Dominik H.; Włodek, Tomasz; Polański, Krzysztof
Wind energy sector has been developing at a fast pace in many countries around the world in recent years. However, there is an issue with the unpredictability of electricity production provided by wind turbines that is caused by variability of weather. Therefore, there is need to compensate the intermittency of wind energy by means of backup power generation facilities. One of the solutions is compressed air energy storage technology (CAES). The paper discusses the CAES technology characteristics as well as economic aspects of CAES plant construction and operation. The latest achievements and developments in the field of CAES technology is presented. The paper inspects the existing CAES facilities and discusses the possibilities of implementing this technology in Poland.
Analysis of reservoir properties and parameters of oil fields suitable for the application of CO₂-EOR method
(2015) Uliasz-Misiak, Barbara; Kosowski, Piotr; Lewandowska-Śmierzchalska, Joanna
The criteria worked out on the basis of the literature study were used for indicating oil fields, where carbon dioxide can be injected for the purpose of storing or to enhance the production of oil. The preliminary selection of oil fields, where the miscible $CO_{2}$-EOR method can be applied was based on the following criteria: depth of deposition, density of oil, reservoir temperature and oil saturation. From among 68 analyzed oil fields, 35 were used for the analyses: 3 fields in the Carpathians, 6 in the Carpathian Foredeep and the remaining 26 fields in the Polish Lowland. The statistical analysis methods were used for analyzing reservoir parameters of fields preselected for the $CO_{2}$-EOR method, i.e. depth of deposition of the roof of the horizon, average thickness, initial reservoir pressure and reservoir temperature. The reservoir properties of these fields were also analyzed, i.e. average permeability, average porosity and average saturation with oil.
Geological and drilling aspects of construction and exploitation geothermal systems HDR/EGS
(2015) Sapińska-Śliwa, Aneta; Kowalski, Tomasz Wojciech; Knez, Dariusz; Śliwa, Tomasz; Gonet, Andrzej; Bieda, Anna
The article presents an overview of developing unconventional geothermal systems, such as Hot Dry Rock Systems (HDR), where is used the heat of dry rock and enhanced system with smali water tributary called Enhanced Geothermal Systems (EGS). These systems provide utilization of geothermal energy in reservoirs (i.a. granites) where conventional methods are not possible to use. Operation HDR/EGS involves the use rock heating through warming medium, which flowing between the production and injection boreholes. In most cases medium introduced artifically by hydraulic fracturing. Currently, most of the projects HDR/EGS is in the implementation phase. Based on gathered materials an analysis of the construction and exploitation geothermal systems. Take into account geological and drilling aspects.
Assessment of the quality of surface water from selected area of active oil exploitation
(2015) Chruszcz-Lipska, Katarzyna; Knapik, Ewa; Rychlicki, Stanisław; Stopa, Jerzy
In this work, the studies of various physico-chemical parameters of surface waters originated from the selected area of oil exploitation in the south of Poland are presented. The water samples were collected from streams and ponds or directly from surface tanks situated in the vicinity of operating wells. The observed values of different parameters like pH, odor, color, turbidity, electroconductivity, concentration of sulfate, chloride, nitrate, iron, calcium, magnesium, ammonium, alkanity, dissolved oxygen or petroleum contamination of samples were compared with standard values recommended by the WHO (World Health Organization) and the relevant Polish Regulation. Preliminary studies show that investigated surface waters are slightly affected by anthropogenic pollution. The main two sources of contamination of water from the study area are agriculture and mining industry.
