Hot oil has been used to remove paraffin deposits almost as long as oil has been produced. It is still the most widely used procedure for paraffin removal in use today because of its relative simplicity of application, immediate results, and low cost per application. These apparent benefits have obscured the damage that hot oil can cause when used to clean downhole production equipment. Formation damage caused by hot oiling is related to the physical characteristics of the oil used, the source of the oil, the formation temperature, and the hot-oil process. Potential problems are discussed and suggestions made to minimize or to eliminate them. Laboratory tests are presented for determining whether a crude will cause formation damage during hot oiling. Case histories of successful cleaning of hot-oil formation damage are also given.
