The price of Iranian crude oil in different markets depends on the price of US crude oil. In recent months, the oil and gas industry and the sale of Iranian crude oil and the co-operation and investments of oil companies operating in the field of oil field development have halted. Therefore, examining the effects of US government policies on the oil market is very effective. The most important ...
Background: Crude oil is a very toxic chemical. Recently, the search for protective substances is attracting attention. This study aimed to investigate the hematoprotective potentials of oil palm leaves against the toxicity induced by crude oil. Methods: Male Wistar albino rats (n=36) were divided into six groups of rats (n=6). Group 1 (controls) were fed with normal rat food. Groups 2 and ...
Backgrounds and Objectives: Oil pollution can be generated as a result of spillage, leakage, discharge, exploration, production, refining, transport and storage of crude oil and fuels in the environment. Consequently, many researchers have developed and studied the chemical, physical and biological methods to degrade crude oil. Among them, the biological treatments are the most interesting as t...
Hedging the risk of crude oil prices fluctuation for countries such as Iran that are highly dependent on oil export earnings is one of the important subject to discuss. In this regard, the main purpose of this study is to calculate and analyze the optimal dynamic hedging ratio for Iranian light and heavy crude oil spot prices based on one-month to four-month cross hedge contracts in New York St...
kilka fish are known as the main industrial and pelagic species of iran that are captured abundantly in the southern caspian sea. this study was conducted to survey the effectiveness of refinement steps on kilka (clupeonella delicatula) crude oil quality and fatty acid profiles. neutralization, bleaching, winterization and deodorization were performed on crude oil with deodorization done under ...
Background: Hydrocarbons degradation is principally achieved by microorganisms in natural environments. The extent of hydrocarbons biodegradation is mainly conditioned by environmental factors and its success depends on the optimal condition for the crude oil degrading isolates. Objectives: The aims of the current study was to isolate and identify crude oil degrading bacterium from surface sed...
Crude oil fouling of the equipment surfaces is a troublesome issue which leads to operating difficulties, economic penalties, increased environmental impacts, and health and safety hazards in petroleum industry. With a rough estimation, a minimum cost of equal to 4 million barrels of oil/year is required to be invested to offset the costs of crude oil fouling in Pre-heat Trains of Iranian oil r...
Water contaminated with diesel oil represents one of the greatest challenges in waste water management. soluble fraction (WSF) is particular interest because its toxicity to aquatic organisms and discharge regulations set by environmental authorities. Biochar sorbents have attracted great attention, due their low cost origin advantageous properties as well high sorption capacities processes. In...
Biomarker compounds that derived from early living organisms play an important role in oil and gas geochemistry and exploration since they can record the diagenetic evolution of the parent materials of crude oil and reflect the organic geochemical characteristics of crude oil and source rocks. To offer scientific basis for oil exploration and exploitation for study area, gas chromatography-mass...
