The formation of troublesome organic deposits during oil and gas production is a significant cause of decreased production and increased lifting costs. Traditional methods of mechanical and solvent-based removal are time consuming, expensive, and can create additional problems of redeposition and dehydration facilities upsets. A novel process has been developed to remove organic deposits from hydrocarbon-producing wells and equipment by generating an exothermic reaction that melts and disperses paraffin wax and asphaltenic deposits. The reaction product is a powerful paraffin dispersant that prevents redeposition after the temperature returns to normal. The process is non-aqueous, which does not cause troublesome emulsions or potentially dangerous gas production.
