Paper: THE USE OF SOLVENTS TO CONTROL PARAFFIN IN ROD-PUMP WELLS AND FLOW-LINES

The accumulation of paraffin deposits in pumping wells and flow lines presents a production and transportation
problem that is very costly to the oil industry. This problem has been attacked in many ways and, until a few years ago, the removal of such deposits was accomplished by mechanical means only. These usually involved lost time, extra labor, and special tools, all of which were expensive to the operator. Because
of the high cost of mechanical methods, it was found that, in many cases, the use of chemical solvents
was a more economical way to remove paraffin deposits. Such solvents, when properly applied, removed
paraffin deposits from the well and flow line, with far less expense to the operator.
