Abstract
The invention relates to a hydrocarbon recovery composition comprising an anionic surfactant, wherein said composition is in the solid state, and to a shaped article comprising said composition. Preferably, said composition is in the form of a powder. Further, the invention relates to a process for treating a hydrocarbon containing formation comprising the steps of a) transporting said composition or shaped article to the location of the hydrocarbon containing formation; b) dissolving said composition or shaped article in water thereby forming an aqueous fluid containing the hydrocarbon recovery composition; c) providing the aqueous fluid containing the hydrocarbon recovery composition to at least a portion of the hydrocarbon containing formation; and d) allowing the hydrocarbon recovery composition to interact with the hydrocarbons in the hydrocarbon containing formation.
