WebA far more serious factor is that extremely hot oil sometimes up to 300 degrees F can carry paraffin back into the formation, and the formation temperature generally is not high enough to allow it to go back into solution. Formation damage is the undesirable result. The primary interest has now centered on the chemical approach.
