Biocide testing for the application in the oil and gas industry
(2015) Turkiewicz, Anna; Brzeszcz, Joanna; Witek, Wiesław; Kapusta, Piotr
The paper discusses tests for effectiveness of three antibacterial substances for application in the national oil and gas industry. The substances were tested with reference to active cultures of microorganisms. These cultures were isolated, inter alia, from drilling fluids, produced waters and extraction sludge, and then multiplied and used in tests discussed in this publication. The tests demonstrated differences in particular tested substances in respect of effectiveness of their impact on aerobic and anaerobic bacteria and fungi. The results of the work will be used in industrial treatments in order to eliminate biogenic contamination, counteract biodegradation of drilling muds, and also for disinfection of reservoirs designed for storing water and other technological fluids.
Residential price of natural gas in Argentina
(2015) Freidenberger, Cristian Gustavo; Śliwa, Tomasz
This article was made to research about natural gas market in Argentina and its price for residential customers. Wellhead, transmission and distribution prices are developed in this paper. In addition taxes and special charges are shown. Commercial consumption is not included in residential consumption. Argentina has changed its natural gas framework in 1992, after this year several regulations transformed the gas market. On the other hand the country lost its self-supply and imports are growing in the last years. In this context natural gas price for residential customers is smali in comparison with international context.
Selected thermodynamic aspects of liquefied natural gas (LNG) pipeline flow during unloading process
(2015) Włodek, Tomasz; Łaciak, Mariusz
Liquefied natural gas (LNG) is transported by ships to unloading points on the LNG terminals, where the LNG is transported by above-ground superinsulated pipelines to storage tanks. Storage tanks are located a few hundred meters to several kilometers away from the unloading point. The article shows the changes in the basic thermodynamic parameters of liquefied natural gas during the flow in the pipeline modeled for an exemplary unloading process for different variants using Peng-Robinson equation of state.
25 years of Gazprom on the gas market
(2015) Kosowska, Katarzyna; Kosowski, Piotr
Gas sector was one of the best growing industries of the Soviet Union in the last two decades of its existence. This was made possible thanks to the discovery and exploitation of natural gas fields in Western Siberia, as well as the construction of transmission infrastructure - domestic and export pipelines. The history of the Russian gas industry is inextricably linked with the activity of Gazprom, the gas concern set up in 1989 in place of liquidated Ministry of Gas Industry. The article gives a summary of the 25-year history of Gazprom and its economic, social and political role. It discusses activities of the company on internal and external markets, issues of gas reserves, production and transmission, as well as the financial and political relationship with the authorities of the Russian Federation.
Comparative analysis of technological efficiency of oil production intensification in carbonate collector. Advantages of the technology of radial drilling
(2015) Ziaja, Jan; Movčan, Vasil'
The paper presents a comparative analysis of the results of radial drilling, drilling perforation, cumulative reperforation and acid treatment. The study was focused at carbonate deposits in Russia. For each technology average incremental oil rates were estimated at the same exploration targets. The analysis of technological effectiveness in the given geologic and physical conditions revealed that drilling perforation and radial drilling allow reaching higher incremental oil rates compared to acid treatment and cumulative perforation. This fact confirms effectiveness of drilling radial canals by enlarging infiltration area. For the sake of completion radial drilling and drilling perforation are performed in the same wells. To reveal limiting conditions of applying radial drilling and drilling perforation an effectiveness analysis is made depending on the thickness of the interlayers exposed. To formulate criteria of radial exposing applicability an analysis of effects of different geological and physical formation parameters on geological and engineering operations effectiveness is done. The following parameters are considered: relation between the current formation pressure and initial formation pressure, formation permeability, skin factor, thickness of interlayers in overall perforation interval, thickness of interlayers exposed by radial canals.
