organic deposit

1. n. [Enhanced Oil Recovery]
A type of damage in which heavy hydrocarbons precipitate when temperature or pressure is reduced. These deposits are commonly located in the tubing, gravel pack and perforations, or inside the formation. The injection of cold treating fluids promotes the formation of organic deposits. Organic deposits such as paraffins or asphaltenes are resolubilized using aromatic organic solvents such as toluene or xylene. Small amounts of alcohol help to further dissolve asphaltenes.
