Controlling Paraffin-Deposition-Related Problems by the Use of Bacteria Treatments

Abstract

Five wells with a history of paraffin related problems were selected for treatment with a commercially available bacteria product.

Design and application of new impeller-type wax-proof device based on speed-increasing wax-proof mechanism

“…The hot washing process can be directly performed if necessary. A shaft seal is provided at the center cross (12), and the sealing is realized through a packing seal, which is used to seal the leakage channel between the hollow rod ( 14) and the wall surface.…”

“…Its advantage is that it has a significant effect and does not cause considerable changes in oil quality. However, the application environment of microbial dewaxing is harsh, and it is only suitable for oil wells with a bottom hole temperature of less than 210 ° F. At the same time, some aerobic bacteria may cause corrosion [12].…”
