During production of crude oil, temperature and pressure of the produced fluid decreases along its production pathway. The reduction in pressure and temperature disturbs the equilibrium of the composition of the oil particularly the heavier components leading to their separation, precipitation and deposition at in-and-around well bore (skin effect) and production tubing. Such a deposition can choke the flow passage from reservoir to well bore and reduce the production of oil appreciably.

A unique two pack chemical system had been developed as an effective tool for:

• Removal of organic deposits, such as in-and around well bore (skin) and production tubing

• Enhancement of production rate

The two pack chemical system when injected into the well bore through production tubing, reacts to produce in-situ heat with a reaction product. The heat generated in the system can dislodge and melt the deposits and the reaction product formed acts as dispersant and an effective surfactant.
