Abstract
A composition can be used for downhole dissolution of a hydrocarbon sludge in a subterranean formation. The composition includes an organic solvent, a surfactant, an organic acid, and a mutual solvent. The organic solvent is configured to dissolve at least a first portion of an organic phase of the hydrocarbon sludge. The organic acid is configured to dissolve at least a portion of an inorganic phase of the hydrocarbon sludge. The surfactant and the organic acid are synergistically configured to increase solubility of the hydrocarbon sludge upon exposure to the composition. The mutual solvent is soluble in oil and in water. The mutual solvent is configured to dissolve at least a second portion of the organic phase of the hydrocarbon sludge. The mutual solvent is configured to increase solubility of the organic acid in the composition.
