After the Exxon Valdez oil spill in Prince William Sound in March, 1989, much work has been done to track the spilled oil and study its fate and its affect on the environment. Our studies involved developing and applying methods to identify and track the spilled Exxon Valdez oil (EVO) as it weathered, as well as to differentiate it from other petrogenic hydrocarbon input sources in PWS. Applica...

The high demand to replace the petroleum fuel makes renewable and sustainable sources such as Palm oil, Jatropha oil and Algae as main focus feedstock for biodiesel production in Malaysia. There are many studies conducted on Palm oil and Jatropha oil, however, the use of Algae as an alternative fuel is still in its infancy. Malaysia already implemented B5 based Palm oil as a feedstock and this ...

A significant quantum of crude oil is trapped in reservoirs and often unrecoverable by conventional oil recovery methods. Further downstream, the petroleum industry is facing challenges to remove sulfur, metal, nitrogen as well as undesirable organic compounds from the crude. Conventional secondary recovery methods such as water and gas injections helped to increase the productivity of the well...

The lubricating properties of vegetable oil are well known. However, with the advent of petroleum oils, castor oil and other vegetable oils fell out of favor. The quality of petroleum oils has improved significantly in the last few years with the introduction of Group III base oils. However, even Group III oils fall short of the inherent lubricity of vegetable oils. Analogous to advances in pet...

Lawrence Livermore National Laboratory (LLNL) is currently involved in a long term study using time-lapse multiple frequency electromagnetic (EM) characterization at a waterflood enhanced oil recovery (EOR) site in California operated by Chevron Heavy Oil Division in Lost Hills, California (Figure 1). The petroleum industry’s interest and the successful imaging results from this project suggest...

Fast pyrolysis oils are one source of renewable liquid fuels, which could be used as green fuels in a sustainable manner. The ASTM D664 method used to determine the acidic constituents in petroleum products, lubricants, and biodiesel requires mixtures of isopropyl alcohol (IPA) and toluene as solvent. The ASTM method also uses large quantities of solvents for the total acid number (TAN) determi...

Accidental aspiration of petroleum products in children can also be witnessed in adults working with petroleum products by siphonage or swallowing fire for demonstration purposes. Ten cases admitted to Yuzuncu Yil University Emergency Service due to fuel oil and gasoline aspiration in a three-year period were retrospectively analysed. All cases were males and their average age was determined as...

The increasing vehicular population causing consumption of petroleum fuels at a faster rate and causes increase in the danger of petroleum fuels depletion and the remarkable increase in high crude oil prices. The increasing consumption of petroleum products has been a matter of great concern for the country for the financial growth as well as environmental pollution abatement. The situation off...

To date, the most common insulating oil used in oil-immersed transformers is mineral (MI) oil, which derived from petroleum. Owing to depletion of petroleum over years, it can be anticipated that petroleum-derived products such as MI oils will also deplete future. are not only non-renewable, but they non-biodegradable, where these harmful environment cases spillage. Therefore, aim this study in...

Introduction. Typically, investment in petroleum exploration and development yields a joint product: reserves of oil and natural gas. The reserve additions are separable, but the expenditures generating reserve additions cannot be neatly partitioned between the two hydrocarbon sources.
