The oil and gas industry will continue to boom in the coming future. Obtaining oil and gas from conventional and non-conventional resources will become more and more challenging. This intensifying need will impose very considerable demands on work force, financial and technology capabilities. Since the future supplies of oil and gas are to expand, advanced technology will become increasingly ne...

chemical composition and physicochemical properties of pumpkin seeds and fatty acids of their oil were determined. it was found that the seeds contained 41.59% oil and 25.4% protein. moisture, crude fiber, total ash, and carbohydrate contents were 5.2%, 5.34%, 2.49%, and 25.19%, respectively. the specific gravity, dynamic viscosity, and refractive index of the extracted pumpkin seed oil were 0....

of heterocyclic nitrogen compounds in crude petroleum oil, were screened under microaerobic conditions, i.e. "itrogen gas substituted conditions. Eight bacteria were isolated and identified. For example, BaeiUus sp. KUKK-4 degraded 31Yk of CA when cultivated for 28 days in a mediurn initially containing CA at 1000mgll rvith shaking under the microaeroblc cond;tions. Teflon-scaled 100-rn1 tcst t...

Red palm oil (RPO) contains high concentrations of beta- and alpha-carotene, and is presumed to possess a higher vitamin A value than other foods. The objective was to determine the metabolic vitamin A and carotene values of refined red palm oil in healthy adult subjects, using a stable isotope reference method. Twelve healthy subjects were administered a small standardised meal containing 10 g...

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...

Workers operating in the oil and gas exploration industries are at risk for exposure to sour gas—gas containing H2S (hydrogen sulfide) at potentially toxic levels. Operations located in densely populated areas pose additional threats of exposure to the general public. The danger can develop over time, even if the gas source was initially “sweet” (low in H2S). Local and national regulations defi...

One of the challenging problems in the Oil & Gas industry is accurate and reliable multiphase flow rate measurement in a three-phase flow. Application of methods with minimized uncertainty is required in the industry. Previous developed correlations for two-phase flow are complex and not capable of three-phase flow. Hence phase behavior identification in different conditions to designing and mo...

The essential oils of the flowering aerial parts of two Ocimum species viz., Ocimum gratissimum and O. sanctum were analyzed by gas chromatography and gas chromatography/mass spectroscopy. The principal constituent of O. gratissimum and O. sanctum was eugenol (75.1%) and methyl eugenol (92.4%), comprising 99.3 and 98.9% of the total oils, respectively. In vitro antimicrobial activity of the ess...

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...

Understanding the dynamics of pore-scale multicomponent gas and oil mass transfer across water "lms during hydrocarbon gas injection in petroleum reservoirs is important in the design of tertiary oil recovery schemes at the "eld scale. The water "lms prevent oil and gas coming into direct contact and, for miscible gas injection, delay the onset of miscibility. We use a pore-scale model to descr...
