Item type:Article, Access status: Open Access , Prospects for the development of hydrate storage and transportation technology of methane gas(2015) Pavlenko, Anatolìj Mihajlovič; Košlak, Ganna Volodimirìvna; Vitâz', Oleg Ûlìjovič; Rybicki, CzesławThe 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.Item type:Article, Access status: Open Access , Application of compact separators in development of nonconventional gas reservoirs(2016) Cepil, Monika; Rybicki, CzesławThe installation to the collection and transport of gas in case of the evil conventional occupies a great many places. When we are meeting variable factors in time e.g. with the efficiency this we are in a position to propose installations smaller and divided into modules which in case of the reduction of the quantity of extracted gas would be able to to be deducted in the easy way or augmented of the existing installation. Economic aspects engaged searches of more effective installations to the cleaning and the drainage of gas. Already from the early 90s of the 20th century, the oil industry sacrificed many attention to methods of the separation. This permitted the discovery of such separators as Gas/Liquid Cylindrical-Cyclone (GLCC). In comparison with conventional, compact separators are easy in the installation and the service, require the small maintenance. The simplicity of the construction, smaller measurements and the balance GLCC provides savings of costs. In the paper authors will review solutions of compact separators and also the preliminary adaptation and the definition of measurements for given parameters of technological exploited of natural gas reservoirs.Item type:Article, Access status: Open Access , Analysis of selected problems encountered while testing natural gas-condensate fields in the Western Carpathians(2015) Rybicki, Czesław; Dubiel, Stanisław; Blicharski, JacekThe potential change of natural gas composition in the near-wellbore zone creates a big problem with the selection of appropriate initial value of counterpressure exerted by the displacement fluid on reservoir during the test, and also with the interpretation of the reservoir and production tests results. The analysis of the industrial data reveals that the effect of condensate production in the near-wellbore zone could take place while using too high counterpres-sure during DST tests, as a consequence of using a relatively high column of water displacement fluid in the DST column, i.e. about 2500 m. This thesis can be confirmed after further detailed theoretical analysis of the occurring thermodynamic conditions. The paper addresses technological and interpretation problems encountered during drill stem tests (DST) of gas-bearing Devonian strata, on the example of the Stryszawa field in the Western Carpathians. Special attention was paid to the possible changes of gas composition during flow tests and the cases of gas condensation of heavier fractions during build-up tests. Attempts were made at explaining sudden drops of pressure at the build-up stage along with the thermodynamic conditions responsible for this effect. The authors explained the necessity of using an appropriate Ful-Flo sampler in the DST set for collecting gas samples at any time of the test, and devices for continuous measurement of temperature. The use of new types of drill stem testers and appropriate interpretation methods, which would account for a detailed analysis of technological and reservoir conditions allows for more efficient oil prospecting and deciding about enhancement methods in hydrocarbon production. The analysis of thermodynamic conditions on the bottom of the wellbore allows for selecting proper counterpressure values in view of the condensation of heavier gas fractions in the near wellbore rocks. The analysis of conditions in which heavier gas fractions undergo condensation is approximate and general because the gas samples were collected at the outlet of the DST string (in surface conditions), without a Ful-Flo sampler and without temperature measurements.Item type:Book Chapter, Access status: Open Access , Analiza przebiegu eksploatacji złoża Węglówka znajdującego się na fałdzie węglowieckim(Wydawnictwa AGH, 2023) Wojnar, Albin; Rybicki, CzesławArtykuł dotyczy analizy przebiegu eksploatacji złoża ropno-gazowego Węglówka położonego w starym zagłębiu naftowym w Polsce południowo-wschodniej na fałdzie węglowieckim. Przeprowadzona została krótka analiza budowy geologicznej i zmian w przebiegu eksploatacji. Fałd Węglówki dzieli się w tym obszarze, podobnie jak na całej swej długości, na trzy sfałdowania: południowe, centralne i północne. Odwierty eksploatacyjne rozmieszczone są głównie na sfałdowaniach centralnym i północnym. W przekroju pionowym można wyróżnić trzy horyzonty oznaczone symbolami I, II, III. Horyzonty I i III są produktywne, a horyzont II – zawodniony. Poziomy roponośne to cienkie warstwy piaskowców (miąższość 1–3 m), często soczewkowato się wyklinowujących, rozdzielonych nieregularnymi warstwami łupków czarnych. Złoże Węglówka generalne eksploatowane było początkowo dzięki energii gazu rozpuszczonego, przez co eksploatacja była samoczynna, a w końcowej fazie – dzięki energii grawitacji. Przebieg wydobycia ropy i gazu wskazuje, że poprzez system uskoków istnieje kontakt z warstwami głębszymi rokującymi zwiększenie wydobycia węglowodorów.Item type:Article, Access status: Open Access , Technology for development of methane-hydrate deposits jointly with receiving fresh water(2017) Denisov, Ûrij P.; Klimenko, Vasilʹ Vasilʹovič; Martinenko, Vìktor; Rybicki, CzesławThe technology of development of bottom gas-hydrate deposits, which allows to receive fresh water simultaneously with methane, is presented. Principal schemes are presented and methods of operation of dual-purpose plants implementing this technology and described on the basis of the methods of gas production from methane hydrates that are most prepared for practical implementation: 1) injection of warm water into the well; 2) depressive effect on the deposit; 3) replacement of methane in hydrates with carbon dioxide injected into the reservoir. The magnitude of the decrease in temperature with the depression effect on the deposit is determined. It is shown that, the amount of fresh water obtained in dual-purpose plants operating with the replacement of methane in hydrates with carbon dioxide is proportional to the coefficient of the recycling rate of $CO_2$. For the considered schemes of dual-purpose plants, processes of decomposition of methane hydrates in the gas-hydrate formation are analyzed, an exergic efficiency estimation is performed. Such installations. The economic efficiency of a single-purpose and dual-purpose gas-producing units operating according to an approved method of depression is considered. It is shown that the most effective are dual-purpose facilities operating using the method of methane replacement in hydrates with carbon dioxide, and the coefficients of economic efficiency of dual-purpose installations are at least 1.2 times higher than similar coefficients of single-purpose gas production facilities.Item type:Article, Access status: Open Access , An analysis of the work conditions in the Bóbrka-Rogi field over the 100 year history of its exploitation(Wydawnictwa AGH, 2017) Wojnar, Albin; Rybicki, CzesławThe Bóbrka - Rogi oil reservoir belongs to oldest reservoirs in Poland. The handmade well named Franek was created by Ignacy Lukasiewicz in 1853. It is currently the object about the historic museum. The accumulation appears in the anticline structure of the Bóbrka fold. As result of study of geological data, this fold has four secondary structures forming separate longitudinal blocks. Moreover transverse dislocations cross the Bóbrka structure on the row of separate deposits. Oil appears in four levels of Ciężkowice sandstones and in layers of the "czarnorzecki" sandstone. The level of the first Ciężkowice sandstone contains oil on the east from the Wietrznianka fault, II level of the Ciężkowice sandstone is oil-bearing within the Wietrznianka fault on the west, up to the Rogi fault on the east., III level of the Ciężkowice sandstone is oil-bearing from the Rogi fault on the east to the Bóbrka fault and partly outside it on the west, IV level of the Ciężkowice sandstone contains oil-bearing horizontals to the west from this block to the fault of the TPS mine. The sandstone Czarnorzecki contains oil-bearing horizontal to the west from the fault of the Jasiołka river. The reservoir belongs to the stratified type in the anticline structure it is shielded lithologically and partly tectonically by dislocations or overthrusts. As it gets out of data of geologically of deposit since the discovery of the deposit one got out of him above 1 200 thousand t of oil and 190 million nm3 gas. The surface of the mining district carries out approx. 2.5 km$^{2}$ . Authors on the basis archival data made the analysis the previous exploitation this reservoir and the evaluation of perspectives of his continued existence with the regard of the possible revitalization of the wells.Item type:Article, Access status: Open Access , Role of biomethane in the improvement of energy safety in Poland(2015) Filanowski, Paweł; Rybicki, CzesławThe renewable energy gains over the recent years on the meaning, also in consideration of increasing prices the energy and some signs of changes of climate caused by the man. Thereby in many countries the large press lies down on the use of renewable sources of energy such as water, the sun, the wind and the biomass covering every now and again the best part of the power requirement. One of method of the production of the energy from the biomass is the production of the biogas in specially to this end constructed devices so called biogas plants. To create of conditions to the development of this field are necessary specific performances supporting and propagating on the domestic grade and regional. In Germany the enforcement of amended law about the renewable energy contributed to true bumu in the sector of the energy production from the biogas. In Germany in 1999 functioned 850 agricultural biogas plants, in 2003 – 1700 and in 2005 – 2800. In Poland until the year 2005 according to data given by the Office of the Regulation of the Energetics worked 64 power plants supported on the biogas. One ought however to remember that this number includes except agricultural biogas plants first of all installations of the refuse dump gas and the biogas on the refinery of sewage. Poland is a rich country in the stony coal field in the face of this the dependency of the country from the import of this raw material is least. In turn of the gas consumption of terrestrial in Poland increases and the perspective of the dependency himself from the import of this raw material until the year 2030 indicates the more and more greater need for the purchase of this raw material besides limits of our country. On the basis the information contained in the report European Putting green Gas Grid from the year 2014 results that the biomethane production in countries of western Europe gains the more and more greater popularity. This results from this that the import of natural gas to Europe is realized almost as a whole from the east direction. In European Union are many countries which import 100% their demand on natural gas to {in the face of} this aspect the reduction of the dependency themselves these countries from the import of gas in the figure {form} of the production of biomethane becomes a key-matter. For the purpose of the improvement of the development of agricultural biogas plants in Poland arose the govern-ment-document going out opposite to postulates about the necessity of the establishment of the system promoting and supporting the production of the agricultural biogas. A foundation „of Directions of the development agricultural biogas plants in Poland in years 2010–2020” is the creation of optimum-conditions to the development of installations producing the agricultural biogas so until the year 2020 to lead to the construction of averagely one biogas plant in every commune using the biomass of the agricultural origin, on the assumption possessions through the commune of applicable provisions to the execution of such undertaking.Item type:Article, Access status: Open Access , Threats to the environment in the areas of abandoned extraction of hydrocarbon deposits(2015) Rybicki, Czesław; Solecki, Tadeusz; Winid, BogumiłaThe environmental problems in past mining areas, where the production process was ended, are connected with contaminations coming from past extraction processes and the risks relating to the abandonment of wells and deposits. The risk could be variable depending on such factors as the geological formation and hydrogeological conditions in the analyzed area, and the condition of abandoned wells. The main source of contamination could be improperly sealed abandoned wells and unplugged abandoned oil and gas wells. The environmental problems could be particularly concern on the area of old historical extraction sites. There are some hydrocarbon deposits, where production i s endedand still it is possible to see places of wells and remains of an old oilfield infrastructure. Unplugged or improperly sealed wells can result in stray gas migration or contamination of soil, ground and surface and ground waters. The end of well exploitation may cause the risk associated to the restoration of formation pressure. This could be the reason of uncontrolled discharge of gaseous and liquid hydrocarbons into shallow depths. Returning to the extraction from some deposits could reduce the formation pressure and constrain uncontrollable leakages of hydrocarbons. This option seems to be environmentally friendly. Authors of the paper made efforts to evaluate the scale and the range of mentioned disadvantageous phenomena.Item type:Article, Access status: Open Access , Interpretation of DST test results for the identification of HC accumulation limits or boundaries in the area of the Carpathians and Carpathian Foredeep (South Poland)(2014) Dubiel, Stanisław; Rybicki, Czesław; Zubrzycki, Adam; Maruta, MichałThe result and interpretation of reservoir tests (DST) are presented in the paper. They were performed in 20 intervals of 17 production wells in years 1995-1997. These wells are located in the Central Carpathians (flysch sand beds) and mainly in the external and internal Carpathian Foredeep (the autochthonous and allochthonous Miocene thin bedded sandstones) and their substratum (mainly carbonates). The basies of the theoretical diagnoses for determining the main types of drainage zones or limits of hydrocarbon accumulations are presented in the form of a short description of the Kappa Company's programmatic procedure (Saphir 202B system). Some diagnostic diagrams for the main reservoir border models are described using the log-log method. Examples of their geological interpretation are also provided.Item type:Article, Access status: Open Access , The analysis of CO₂ injection in depleted gas reservoirs during the sequestration process(2015) Gonet, Kamil; Blicharski, Jacek; Rybicki, CzesławOne of increasingly used methods for reducing carbon dioxide emission to atmosphere is CCS technology (Carbon Capture and Storage). The last element of sequestration technological chain, after capturing and transporting, is $CO_{2}$ storage which is currently considered in: natural environment, oceans and geological structures – of which depleted gas reservoirs have high sequestrating potential mainly by virtue of proven record of geological recognition and high recovery factor, hence, great storage capacity. This paper is connected with first stage of $CO_{2}$ storage in depleted gas reservoir i.e. flow of injected fluid inside the well. Conducted analysis was concerned about $CO_{2}$ flow conditions inside the injection well in various stages of $CO_{2}$ storage process, and furthermore, relation between reservoir pressure, injection rate, well diameter. Moreover, the thermodynamic conditions and its impact on changeability of PVT parameters and hence phase changes were also investigated.
