Abstract
ABSTRACT Heat is often required to stimulate production in wells with recurrent histories of paraffin deposition and plugging. A chemical system which produces heat and nitrogen at a predetermined well depth is proposed as an alternative to the traditional hot oil and steam generation treatments. The system is described briefly and case histories are given for 3 wells in California and 5 wells in Wyoming. The field results indicate that heat produced by the nitrogen generating system effectively stimulates production from paraffin plugged wells. The heat and nitrogen generating system further shows increased production cycle lengths over those which result from hot oil or paraffin solvent treatments. Beneficial effects of including a paraffin inhibitor in the treatment design are discussed, along with other potential applications for the heat produced by this system.
