Opis:
Generally hydrocarbons reservoirs can be divided into conventional reservoirs and unconventional reservoirs. Conventional reservoirs belong these reservoirs which can be used directly after the discovering process. Unconventional reservoirs - reservoirs which after the discovery process have to be prepared to be effective. Unconventional gas resources are targets for development in order to contribute to a national energy mix. Better recognition of the unconventional gas reservoirs allow us to obtain good results after discovering them. The main subject of this paper is giving some details about the testing methods of unconventional reservoirs and their properties and characteristics.

Opis:
The 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.

Opis:
The 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 km2. 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.

The 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 P utting 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 agricu ltural biogas plants in Poland arose the government-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.

Opis:
In order to prevent CO2 concentrations in the atmosphere rising to unacceptable levels, carbon dioxide can be separated from the flue gas, for example from a power plants and subsequently sequestrated. Different technologies for carbon dioxide sequestration can be proposed. They are: - storage in depleted gas reservoirs, - storage in oceans and aquifers, - sequestration CO2 by means of so-called "mineral CO2 sequestration". A depleted gas reservoir represents an attractive target for carbon sequestration for several reasons. It contains a geological trap, transport and injection infrastructure. Moreover CO2 injection can be thought as enhance gas production either by re-pressurization or pressure maintenance. The purpose of this paper is to evaluate storage capacity of carbon dioxide in a depleted gas reservoir in relation to the recovery factor of hydrocarbons. A material balance equation for CO2 sequestration proposed by Lawal and Frailey (Lawal, Frailey, 2004) was modified to predict a CO2 sequestration volumes. On the basis of derived material balance equation there were made calculations for a chosen natural gas reservoir.
W celu obniżenia wzrostu koncentracji dwutlenku węgla w atmosferze może on być wychwytywany z gazów spalinowych pochodzących głównie ze stacjonarnych źródeł emisji, np. elektrociepłowni, i składowany w formacjach geologicznych. Istnieje wiele potencjalnych technologii sekwestracji dwutlenku węgla m.in.: w sczerpanych złożach gazu ziemnego, w geologicznych strukturach zawodnionych, na dnach oceanów i inne. Sczerpane złoża gazu ziemnego stanowią naturalne zbiorniki geologiczne i mogą być wykorzystane do celów sekwestracji CO2, za czym przemawiają następujące fakty: stanowią one naturalne szczelne pułapki geologiczne, posiadają infrastrukturę wgłębną i napowierzchniową, ponadto zatłaczanie CO2 do sczerpanych złóż pozwoli na uzyskanie większego stopnia sczerpania węglowodorów przez podtrzymywanie czy też podniesienie ciśnienia złożowego. Celem artykułu jest przedstawienie metodyki oceny pojemności magazynowej głównie sczerpanych złóż gazu z zastosowaniem metod bilansu masowego. Autorzy dokonali modyfikacji modelu bilansu masowego zaproponowanego przez autorów (Lawal, Frailey, 2004) do sekwestracji CO2 w złożach gazu w celu określenia ich pojemności magazynowych. Przeprowadzono także obliczenia dotyczące przykładowego złoża znajdującego się w końcowej fazie eksploatacji.

Opis:
The purpose of underground gas storage in porous media is to allow compensation for peak shaving in gas consumption. Especially during the winter months, the stored gas must then be supplied at fuli capacity for short periods. Currently storage capacities of existing UGS facilities in Poland are not fully sufficient for proper regulation of gas demand. The more they do not overcome long term limitation in gas supply from import. There is therefore a need for increasing capacity of existing UGS or development of new ones. This paper presents an analytical model based on equations of material balance combined with well inflow and tubing performance equations for modeling gas storage operations. Presented model was used to maximize the capacity and efficiency of natural gas storage developed in partially depleted gas fields located in the region of south-eastern Poland for a given reservoir/well configuration. On the basis of this model variant scenario of gas storage operation with the use of vertical and horizontal wells were demonstrated.

In this paper the types of membranes used for purification of the gas streams were described, the principle of operation was discussed and the main areas of the industrial use of this type of separation equipment in the world were identified. The possibility of using membranes for natural gas purification in particular the unconventional gas (shale gas, natural gas with nitrogen) was analyzed. The authors presented the criteria for selecting the size of the membranes, the critical parameters of membrane system, the necessary installation and compilation of technology enabling the proper conduct of the separation process. Based on the experience of different companies rated the advantages and disadvantages of using membranes for gas treatment in Polish exploitation and transmission conditions both from the technological and the economic point of view. The paper ends with proposals for the possibility of application of the system of membranes for the purification of gas from unconventional sources.

Opis:
In the south part of the Carpathian Foredeep basement, between Bochnia and Ropczyce, the Upper Jurassic (Oxfordian, Kimmeridian and Tithonian) carbonate complex plays important role as a hydrocarbon bearing formation. It consists of shallow marine carbonates deposited in environments of the outer carbonate ramp as reef limestones (dolomites), microbial - sponge or coral biostromes and marly or micrite limestones as well. The inner pore space system of these rocks was affected by different diagenetic processes as calcite cementation, dissolution, dolomitization and most probably by tectonic fracturing as well. These phenomena have modified pore space systems within limestone / dolomite series forming more or less developed reservoir zones (horizons). According to the interpretation of DST results (analysis of pressure build up curves by log - log method) for 11 intervals (marked out previously by well logging due to porosity increase readings) within the Upper Jurassic formation 3 types of pore/fracture space systems were distinguished: - type I - fracture - vuggy porosity system in which fractures connecting voids and vugs within organogenic carbonates are of great importance for medium flow; - type II - vuggy - fracture porosity system where a pore space consists of weak connected voids and intergranular/intercrystalline pores with minor influence of fractures; - type III - cavern porosity system in which a secondary porosity is developed due to dolomitization and cement/grain dissolution processes.
W pracy scharakteryzowano metodykę interpretacji testów odbudowy ciśnienia z użyciem krzywych diagnostycznych i specjalistycznych oraz przedstawiono wyniki interpretacji testów złożowych rurowymi próbnikami złoża (RPZ) wykonanych w latach 1995-1997 w 11 profilach serii węglanowych górnej jury (malmu) budujących podłoże zapadliska przedkarpackiego w strefie Bochnia - Ropczyce. Uzyskane wyniki oraz szczegółowa interpretacja krzywych odbudowy ciśnienia dennego w powiązaniu z rozpoznanym rozwojem litofacjalnym utworów górnej jury pozwoliła wstępnie wydzielić charakterystyczne typy wykształcenia przestrzeni porowej, występujące w obrębie interwałów wytypowanych badaniami geofizyki wiertniczej do testów RPZ. Są to: I - typ szczelinowato-porowy z dominującym wpływem systemu szczelin; II - typ porowo-szczelinowaty z minimalnym wpływem szczelin oraz typ III - kawernisty, w którym system wolnych przestrzeni tworzą mikrokawerny, pustki i przestrzenie międzykrystaliczne powstałe głównie wskutek epigenetycznych procesów dolomityzacji i rozpuszczania. Wydzielone systemy można wiązać z facjami skał węglanowych, głównie organogenicznych, występujących w obrębie utworów górnej jury podłoża zapadliska przedkarpackiego.

The 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.

An NMR study of polycrystalline Pr$\text{}_{0.5}$Ca$\text{}_{0.5}$Mn$\text{}_{1-x}$Ga$\text{}_{x}$O$\text{}_{3}$ (x=0 and 0.03) at 3 K is presented. Zero field spin-echo spectra of the Ga doped compound consist of an overlapping $\text{}^{69,71}$Ga signal at 74~MHz (hyperfine field of 5.3 T), a $\text{}^{55}$Mn double exchange line at 375 MHz (35.5 T) and a weak Mn$\text{}^{3+}$ signal between 400 and 550 MHz. Measurements in an applied field show a step-like increase in the double exchange line intensity, which corresponds to an increase in the amount of the ferromagnetic metallic phase. This coincides with a step-like feature in the bulk magnetization measurements. The effect is similar to that in the previous field dependent $\text{}^{55}$Mn NMR measurements of Pr$\text{}_{0.67}$Ca $\text{}_{0.33}$MnO$\text{}_{3}$. At the demagnetized and remanent state, a variation of spin- spin relaxation time, T$\text{}_{2}$, across the $\text{}^{55}$Mn line, due to the Suhl-Nakamura interaction is observed, which suggests that the ferromagnetic metallic double exchange regions, at liquid helium temperatures, are at least 4 nm in size.

The spin-echo spectra measured at 4.2 K and zero field consist of a double exchange line corresponding to the ferromagnetic metallic regions. The line intensity is more than an order of magnitude lower for the $\text{}^{18}$O compound, which indicates an order of magnitude lower content of the ferromagnetic metallic phase in this compound. The frequency dependence of the spin-spin relaxation time T$\text{}_{2}$ shows a pronounced minimum at the center of the double exchange line of both compounds due to the Suhl-Nakamura interaction, which indicates that the ferromagnetic metallic regions are at least 10~nm in size. The results are discussed in terms of the influence of oxygen isotopic substitution on phase segregation.
