Single cell oil, also known as Microbial oil consists of the intracellular storage lipids, triacyglycerols. It is similar to vegetable oil , another biologically produced oil. They are produced by oleaginous microorganisms, which is the term for those bacteria, molds, algae and yeast, which can accumulate 20% to 80% lipids of their biomass. [ 1 ]
Petroleum microbiology is a branch of microbiology that deals with the study of microorganisms that can metabolize or alter crude or refined petroleum products.These microorganisms, also called hydrocarbonoclastic microorganisms, can degrade hydrocarbons and, include a wide distribution of bacteria, methanogenic archaea, and some fungi.
The microbial processes proceeding in MEOR can be classified according to the oil production problem in the field: wellbore clean up removes mud and other debris blocking the channels where oil flows through; well stimulation improves the flow of oil from the drainage area into the well bore; and
The Gravberg-1 well only produced 84 barrels (13.4 m 3) of oil, which later was shown to derive from organic additives, lubricants and mud used in the drilling process. [ 32 ] [ 33 ] [ 34 ] Kudryavtsev's Rule has been explained for oil and gas (not coal)—gas deposits which are below oil deposits can be created from that oil or its source rocks.
The combustion of crude oil releases sulfur oxides (SO x) to the atmosphere, which are harmful to public health and contribute to serious environmental effects such as air pollution and acid rains. [ 2 ] [ 3 ] In addition, the sulfur content in crude oil is a major problem for refineries , as it promotes the corrosion of the equipment and the ...
Microbial biodegradation is the use of bioremediation and biotransformation methods to harness the naturally occurring ability of microbial xenobiotic metabolism to degrade, transform or accumulate environmental pollutants, including hydrocarbons (e.g. oil), polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), heterocyclic compounds (such as pyridine or quinoline ...
Crude oil development and production can include up to three distinct phases: primary, secondary, and tertiary (or enhanced) recovery. During primary recovery, the natural pressure of the reservoir or gravity drive oil into the wellbore, combined with artificial lift techniques (such as pumps) which bring the oil to the surface. [1]
Microbial hydrogen production. Biohydrogen is H 2 that is produced biologically. [1] Interest is high in this technology because H 2 is a clean fuel and can be readily produced from certain kinds of biomass, [2] including biological waste. [3]
