One of 3 common methods to remove nitrogen from natural gas. In solvent recovery processes, the hydrocarbons in the feed stream are absorbed by a chemical solvent and the nitrogen that remains is dispersed by vent. The hydrocarbons are recovered from the solvent through a series of flash operations. Because the process requires that the …

Algerian State owned energy group and is the largest African O&G company, ranking # 12 globally for petrol, 2nd for LNG and 3rd for natural gas exports. Algeria pumps about 1.4 million barrels of oil per day and exports 62 billion cubic meters of gas a year, mostly to Europe
Poor quality gas – natural gas containing more than 1-1/2 grains of hydrogen sulfide per 100 cubic feet. One of the most important parts of gas processing involves the removal of sulfur and carbon dioxide. Because of the rotten smell provided by its sulfur content, this natural gas is called ‘sour gas’. This sulfur can …
Catch-all term for all types of combustible fuels (nuclear and fossil fuels, biomass, alcohol, etc.) and renewable energy resources (hydroelectric, wind, tidal, solar, etc.). As competition increases in US energy markets and as global energy markets become more attuned to the need for non-polluting and/or renewable source energy, end-use customers may soon be able to …
A rock from which oil or natural gas is generated from organic materials. Source rocks are geologically rare. 90% of the world’s petroleum is generated in 6 discrete intervals, representing about 30% of post Cambrian geological time. Most petroleum is geologically recent – 67% is generated and trapped in the last 80 million years, whilst …
The 692 km pipeline has been designed to transport gas from the Shah Deniz field in the Azerbaijan sector of the Caspian Sea, through Georgia and on to the Georgia-Turkey border. The pipeline will eventually be able to transport 16 bcm of gas per year
The $14.65 billion South Stream project signed in 2007 by Gazprom (50%) and Italy’s Eni (50%) is designed to carry mostly Central Asian gas to Western Europe at a capacity of up to 30 bcm/year. Construction is due to take at least four years and is expected to begin in 2008-2009. This pipeline could have …
Spinning reserve is any back-up energy production capacity which can be made available to a transmission system with ten minutes’ notice and can operate continuously for at least two hours once it is brought online. Spinning is derived from hydroelectric and combustion turbine terminology. Reserve generator turbines can literally be kept spinning without producing any …
Sediment is loose, hard material lying on top of solid rock. Sediment comes in many forms and sizes, and can originate from a variety of sources and is usually material deposited by water, wind or glaciers
These are various physical measurements of the nature of the reflected event which may be used for predicting rock properties or hydrocarbon presence. The attributes can be related to reflection of strength, phase, frequency or ratios/relationships with neighboring seismic traces. Advanced attributes include inversion, AVO, coherency and spectral decomposition. Attributes can give indications of: hydrocarbons …
