... Abstract The removal of unreactive or non-acidic sulfur species to meet fuel specifications remains a challenge in the oil and gas industry. This is especially the case with the recent introduction of IMO 2020 restrictions in the use of marine fuels to those that have sulfur contents from 3.5...

... in studying it in the laboratory under the anaerobic conditions typically found in the oilfield. These problems and solutions to some of them are discussed. The paper presents laboratory and limited field data showing how the deposition of ferrous sulfides may be reduced significantly. sulfur wax...

...). Abstract Iron sulfide scale is present in sour gas, oil and water wells. It is present in various chemical species with different iron to sulfur ratios. Iron sulfide species with high iron content is soluble in acids, whereas those rich in sulfur are almost insoluble in acids. Iron sulfide scale...

... temperatures results in complicated chemical and physical changes of the fluids. Hydrothermolysis of the crude oil by the fireflood resulted in a lower sulfur content, a shift in the distillation curve toward increased amounts of lighter components and a slight increase in the API gravity and a decrease...
