Title: Inhibition of paraffin wall deposition in oil lines
Inventor: RZEZNIK LAWRENCE
IPC: E21B41/02
Filed: 2007-08-29
Abstract: Disclosed herein is a method for treating hydrocarbon fluids to inhibit the deposition of paraffin compounds on the interior of pipes and other surfaces. The method includes injecting a catalyst fluid containing scale forming compounds into the hydrocarbon fluid. The scale forming compounds may be calcium carbonate, calcium bicarbonate, calcium, bicarbonate barium sulfate, or other compounds and ingredients. The catalyst fluid may be an aqueous or non-aqueous solution. The method further includes inducing an electromagnetic field in the fluid so as to cause the formation of seed crystals from the scale forming compounds. The paraffin will then adhere to the seed crystals, i.e., scale particles. The resulting particles can then be filtered out or otherwise removed from the solution. Paraffin deposition on the interior of pipes and other surfaces is therefore inhibited. Also disclosed herein are hydrocarbon wells and other piping systems constructed to take advantage of the described techniques.
