Determination of Hydrocarbons in Seawater Extracts of Crude Oil and Crude Oil Fractions
Nature, 1971IN spite of very convincing evidence to the contrary, crude oil and oil products are still occasionally considered to be “insoluble” in aqueous systems. In view of recent reports of major ecological disruptions caused by oil pollution1,2, it seemed imperative to collect more data on the solubility of oil and oil products in water systems3,4.

Chemistry and Technology of Fuels and Oils, 1968 1. The curde oils from the Tengutino, Severo-Kamyshan, and Krasno-Kamyshan fields (N-APT) and that from the Kaspiisk field (baios) in the Kalmykian Autonomic Socialistic Soviet Republic are light, and contain a large amount of paraffins, but the sulfur content is low.

Petroleum originates from the bitumen of source rocks. Migration, however, and especially primary migration, is the cause of considerable changes in composition when bitumen is compared to petroleum. On the one hand, only a small amount of the total dispersed bitumen is mobilized and transferred into carrier or reservoir rocks, and an even smaller ...

Various crude oil classifications have been proposed by geochemists and petroleum refiners. The purpose of these is very different, and also the physical or chemical parameters which have been used in the classifications. Petroleum refiners are mostly interested in the amount of the successive distillation fractions (e.g., gasoline, naphtha, kerosene ...

Telemetering in the crude oil and crude oil products pipeline industry [PDF]
Electrical Engineering, 1961 From modest attempts to transmit data over short distances, telemetering systems in the pipeline industry have been developed which can transmit practically any variable to any desired point. Although present systems are highly sophisticated, many problems remain to be solved. A review of pipeline systems from early beginnings should help clarify these

Photooxidation is a potentially significant process in the degradation of crude oil spilled at sea. Moreover, a fundamental understanding of the effect of photochemical degradation on crude oil is a prerequisite for providing an accurate description of the recent history and potential fate of oil spilled in a marine environment.

Abstract A series of experimental viscosity data for seven different North Sea oils is presented. A new corresponding states method for prediction of the viscosity of both gaseous and liquid hydrocarbon fluids has been developed. The required input is critical constants and the molecular weight of each component.

The treatment of emulsified crude oils has been a problem for years in thepetroleum industry. Until comparatively recently various methods of settlingwith and without chemicals have been used with indifferent success. Since wellshave been acidized, emulsified crudes have been produced, which addconsiderably to the need for improved methods of treatment.
