Formation damage caused by the precipitation and deposition of paraffin or asphaitene particles has been a recurrent problem in the production of crude oil.

A number of well established oilfield operations have been found to aggravate these organic deposition problems. Laboratory testing of crudes and chemical additives has led to a number of solutions to these problems. Case history information on testing, chemical application, and subsequent field results are presented.
