China-Myanmar oil & gas pipeline project covers 7,676 miles in all. The project met with complex geological conditions, construction types along the line, and long-distance oil & gas parallel laying pipeline. Because the pipeline layout and the construction are more complicated, it is necessary to make the stress analysis of oil & gas parallel laying pipeline traversing tunnels. Software CAESAR...

carbon dioxide flooding is considered to be one of the most effective enhanced oil recovery methods for the light oil reservoirs. depending on the operating pressure, the process might be miscible or immiscible. minimum miscibility pressure (mmp) is the most important parameter for assessing the applicability of any miscible gas flood for an oil reservoir. the miscibility condition is determine...

Use of liquefied petroleum gas (LPG) in compression-ignition (C-I) engines has always been considered important in the diesel engineering field. This is due to its easy accessibility and good combustion characteristics. In this paper the application of LPG fuel along with diesel oil in a direct- injection automotive diesel engine is experimentally investigated. In order to convert the pure dies...

We investigate the pricing formation of natural gas markets on three different continents (Europe, Asia and North America). We find that natural gas markets showed a strong relationship with the crude oil market between 1992 and 2001 and natural gas prices tended to thermal parity with crude oil prices. From 2002 natural gas markets exhibited a less pronounced relationship with the crude oil ma...

The need for oil and natural gas as a major source of energy is vital. On the one hand, it has affected the political and economic equations at the international, regional and national level. On the other hand, it has had negative effects on sociocultural, legal, and environmental aspects as well as on the physical and mental health of human beings. Therefore, the need to provide an environment...

the experimental study and modeling of gravity drainage during water alternative gas injection, wag process, in carbonate rock for one of the iranian off-shore reservoir at lab-scale were carried out. the mechanism of gravity drainage during the wag process, and its contribution to the oil recovery in the fractured carbonate reservoirs were also studied. in the wag process alternatively gas is ...

Abstract Oil is a generic term that can cover very wide range of natural hydrocarbon-based substances and also refined petrochemical products. Crude oil petroleum products have physical properties on the basis which their behaviour in marine environment differ widely. These from viscosity (the rate at liquid flows), density, specific gravity (density relative to water).

Background and purpose: The safety climate shows the attitude and general perception of the organization's management regarding safety, which is aimed at investigating the impact of safety training on the safety climate of operational employees working in West Oil and Gas Company. Materials and Methods: This study is quasi-experimental interventional research, which was conducted in the first ...

Colorado and Pennsylvania, like parallel universes, provide strikingly different examples of how external forces affect the evolution of oil and gas conservation jurisprudence originating from a common starting point. This jurisprudence includes both “Classical” oil and gas conservation—measures to prevent waste of the oil and gas resource, and “Values” oil and gas conservation—measures that ad...
