Cymbopogon olivieri essential oil from aerial parts was analyzed by gas chromotography and gas chromatography-mass spectrometry and led to the identification of 38 compounds. Piperitone (72.8%), 4-carene (11.8%) and β-himachalene (7.6%) were found as the major components of the oil. The antimicrobial activity was achieved using disc-diffusion and microbroth dilution assays and microbicidal kine...

The world’s production of conventional hydrocarbons will soon decline. Hydrocarbon shortages are inevitable unless radical changes occur in demand, or in the supply of non-conventional hydrocarbons. The details are as follows: Global conventional oil supply is currently at political risk. This is because the sum of conventional oil production from all countries in the world, except the five mai...

Natural gas comprises about a quarter of the United States' energy use. It is more environmentally friendly than oil and coal due to lower carbon dioxide (CO2) emissions per unit, less costly per unit of energy and more readily available domestically in abundant supply. However, due to a number of barriers in the political, infrastructural, pricing and other arenas, the use of natural gas as a ...

This article is study of Azerbaijan oil and gas industry. It illustrates the business climate, the impact of this sector on Azerbaijan’s economy including role of SOFAZ and highlights recent developments in the energy production and the main concepts of Azeri PSAs. Meanwhile, the article establishes the government policy by indentifying several factors that influenced to attract foreign investm...

An experimental investigation on waste combustion characteristics of a mass burn incinerator is conducted in this study. Three different charging modes, including operator manipulation, periodic feeding, and temperature control, are taken into consideration. The results indicate that the burning characteristics in the combustion chambers are closely related to the operating modes. For the opera...

In this environment, oil and gas companies are seeking opportunities to improve processes and technologies to remain competitive. Upstream oil and gas companies need integrated views of their production processes all the way from the reservoir to the pipeline. They must optimize their processes and perform predictive analysis of production problems to minimize losses. In downstream operations, ...

Platforming, the sharing of parts, processes, knowledge, and technologies, across products and projects has proven to be an effective way for firms to reduce their costs. While platforming is now common in many consumer and industrial products, the use of platforms is a relatively new practice in the design of civil and industrial projects such as buildings, power grids, and oil and gas facilit...

The exploration of offshore gas/oil has been moving to deepwater fields as big reservoirs have been found and technologies have improved. Presently, the most active areas in deepwater gas/oil field development are Africa and the GOM (Gulf of Mexico) in North America. There are many technological challenges in developing deepwater gas/oil fields such as: flow assurance, subsea systems, riser sys...

• The damage to older buildings in the areas suffering the most wind damage was very similar to the damage in the most damaged areas in the Whitsunday Islands from Cyclone Ada in January 1970, Townsville from Cyclone Althea in December 1971, and older buildings in Innisfail from Cyclone Larry in March 2006, not much greater than in the worst affected areas of Cyclone Winifred in 1986, and an or...

Maintenance strategies for subsea oil and gas production installations entail the use of specialized equipment and vessels to carry out subsea interventions. The costs for carrying out preventive maintenance are significantly lower compared to the costs of unpredicted failures where in some cases it is necessary to reduce or stop the oil production. Based on a literature review and inputs from ...
