    Opis:
    The 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 dualpurpose 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 CO2. 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.

    Opis:
    In this article the construction and mathematical model of four-phase separator is realized, which is based on inertial separation mechanism of gas-liquid-sand mixture. Also we have put the problem on the basis of this model to obtain the dependence of separator efficiency on the parameters which play a crucial role in the technological process of separating gas-oil-water-sand mixture into a solid, liquid and a gas phase.

    Opis:
    The manner of estimating water drive gas reservoir recovery can vary considerably. Several mathematical models have been developed for estimating water influx in petroleum industry, but the current paper will address the application of Fetkovich aquifer model to predict the gas reservoir performance considering the pressure changes that gradually occur within the aquifer and between the aquifer and reservoir. The applicability of this model has proven to be extremely useful in estimation of initial gas resources, aquifer volume and its parameters, confirming the producing mechanism but also forecasting the production performance of the gas reservoir. The authors will highlight through some case studies, the importance of the water influx analysis and prediction, in particular for natural gas reservoirs, which subsequently allows for adequate planning in optimizing the reserves’ recovery.

    anticline of Bóbrka
    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.

    Opis:
    During exploration and extraction of hydrocarbon deposits, the risk of elevated methane concentration above the lower explosive limit occurs. In some cases a higher concentration of hydrogen sulfide threatening the health and life of the crew also may be observed. The use of a portable gas detector Dräger X-am 5600 for constant monitoring of methane and hydrogen sulfide concentration in dangerous situations is proposed in the paper. Thanks to the IR sensors and modern electrochemical sensors, this detector allows for monitoring of 6 types of gases simultaneously. The applied infrared sensor IR EX allows for measuring explosive and combustible gases both within the lower explosive limit, and also measuring of methane in the range of 0 to 100 vol.%. The measured values are stored in the computer and also sent to the central through GSM.
