Downhole organic deposition is a common oil well problem. If not properly diagnosed, it can be missed or mistaken for other forms of damage. There are two general organic deposition products in oil wells: paraffin (wax) and asphaltene. Paraffin may also occur in gas wells producing condensate. Neither paraffin nor asphaltene is soluble in acid. They must be treated with solvent, preferably an aromatic, such as xylene or special blends—including those containing naturally occurring terpenes.
Most crude oil contains a chemical compound called asphaltenes. Asphaltenes can be easily destabilized, causing them to form an insoluble solid, or precipitate out, during many operations performed on a well. When this happens, wells can experience plugging that leads to decreased production. In Sharif Petro Energy, a number of additives and solvent systems can be tested specifically to address this issue, we ensure treating fluids are less likely to destabilize asphaltenes, and can disperse or remove any that do form.
