The emission of gaseous hydrocarbons (CH4, C2H4, C2H5 and C3H8) and the permanent gases, O2 and CO2 from soils, has been measured during several weeks. Therefore, eighteen soil samples from different regions in Belgium were selected. The gas samples
Gasgeneration, Migration und Akkumulation am Beispield einer Erdgaslagerstätte in Kluftspeichern des Rotliegenden. (Genesis, migration and accumulation of gas at the example of a gas deposit in a jointable reservoir of the Rotliegende)
A natural gas deposit of the jointable-reservoir type was formed in the intramontane Rotliegende of a local subsaliniferous structure due to fracture tectonics. The genesis of the gas is outlined. The gas goes back to incoalation underlying Silesian
deformations led to a mobilization of the dispersed incoalition gases by efficient joint systems. This process is studied in detail and described in the form of a model of migration and accumulation up to the formation of the recent gas deposit of the jointable
International map of natural gas fields in Europe. 1:2500000. Explanatory note / prepared under the auspices of the Committee on Gas of the United Nations, Economic Commission for Europe (ECE)
Erdol-Erdgas-Geologie und Plattentektonik. (Oil and gas geology and plate tectonic)
Several processes of oil and gas geology are studied in connection with plate-tectonical processes. Thus it becomes clear, that there is a distinct difference between the Paleozoic development of the Europian plate and the Mesozoic development. (HL).
Whither long-term Canada-U.S. natural gas trade? A view from the (modelling) trenches
Canada ; Demand ; Economic environment ; Export ; Importation ; International trade ; Model ; Natural gas ; North America ; Pricing ; Supply ; United States
The paper provides a modelling perspective on charting the course of future North American gas trade. The principal conclusion is that, due to major uncertainties arising from several sources, decision makers must exercise much caution when basing
their decisions or judgments on outcomes from long-term gas trade models.
Central Asia's oil and gas pipeline network: current and future flows
Asia ; Economic flow ; Export ; Hydrocarbon ; International relations ; International trade ; Natural gas ; Natural resources ; Network ; Oil ; Pipe-line ; Soviet Central Asia ; Transport
Several new pipeline projects today are under consideration to facilitate trade, involving largely the transport of oil and gas from Kazakhstan, Turkmenistan and/or Azerbaijan. This paper examines current and expected future flows of oil and gas
Consumption ; Data ; Economic environment ; Export ; Natural gas ; Pipe-line ; Price fixing ; Production ; Russia
Russia's natural gas industry has been successful over the past quarter century. There was a difficult transition period during the last five years, and the situation has become far more unsettled. The A. identifies and analyzes emerging new forces
associated with the economic transition and assesses their impact upon the natural gas sector in terms of production trends and related developments in demand (internal consumption and exports).
The effects of gas flaring on crops in the Niger Delta, Nigeria
Agriculture ; Air temperature ; Crop yield ; Delta ; Fire ; Natural gas ; Niger ; Nigeria ; Oil exploration ; Pollution ; Soil temperature ; Spatial analysis ; Statistical analysis
This study explores the effects of gas flaring on commonly cultivated crops in the Niger Delta region of Nigeria. It attempts a spatial gradient analysis of crop growth and development near a gas flaring site at Eleme, Rivers state, Nigeria.
Definitions of security in German and Polish debates about Russian gas pipelines

and illustrated this fear by picturing a burning candle. The paper pointed out that the supply of gas was threatened by gas-needy and unstable countries along the road. The aim of this paper is to analyse the changing discourses of security in German and Polish
Ice segregation and gas distribution in permafrost using tomodensitometric analysis
Canada ; Cold area ; Core sampling ; Ice ; Natural gas ; Permafrost ; Quebec ; Research technique
This paper presents the application of an innovative and non-destructive approach that makes use of a tomodensitometric scanner to image and characterize permafrost : ice lenses, soil layers, faults, sedimentary structures, gas bubbles. The shape
and spatial distributions of gaseous inclusions in the permafrost provide some clues on gas source and on the thermo-mechanics of ice segregation during permafrost aggradation.
This article investigates whether natural resource endowments, specifically oil and gas, and thepolitical status of ethnic groups interact to increase or decrease armed conflict risk. Based on data from Africa (1990-2010), it founds
that there is very clear and strong evidence for a conditioning effect for groups with a monopoly over national-level political institutions. Oil and gas in grid cells with powerful, nationally represented groups reduce conflict risk, while otherwise increasing
Greenhouse gas fluxes between land surfaces and the atmosphere
The objective of this article is to review the present state of knowledge concerning the contribution to climatic change and other environmental problems of trace gas fluxes between the land surface and the atmosphere. The gases which are most
