An improved method of transporting viscous hydrocarbons containing at least 10 to 15 percent water from a well bore hole or between two points via pipeline which comprises adding to the viscous hydrocarbon containing water a sufficient amount of a nonaqueous solution or dispersion of a surfactant to form a low viscosity oil-in-water emulsion which is easily transported.

Method of transporting viscous hydrocarbons

This invention relates to particulate compositions containing chemical additives for petroleum systems. The particulate compositions when added to petroleum systems gradually dissolve over a period of time, releasing the chemical additive, so as to improve the petroleum system. The use of such particulate compositions has an advantage over the use of the chemical additive itself since the pellets give longer residence time and sustained treatment over a longer period.

Particulate compositions

This invention relates to the removal of organic deposits containing asphaltenic compounds from surfaces with hydrocarbon-substituted arylsulfonic acids such as alkaryl sulfonic acids; a composition comprising a mixture of:
