Paraffin deposition has long been a problem for many oil producing areas. The use of paraffin inhibitors, which are sometimes referred to as wax crystal modifiers or pour point depressants, have been effective at reducing problems caused by paraffin deposition. These materials must be applied at a point before the paraffin falls out of solution and they must be present on a continuous basis. This presentation describes a technique for squeezing inhibitor into the reservoir rock matrix to get a slow consist return of inhibitor that provides an extended treatment for controlling deposition.
