Abstract

See full text

Corrosive effects arising during well treatment applications are inhibited and/or prevented by introducing into the well composition containing a corrosion inhibitor of a biosurfactant selected from glycolipids (other than sophorolipids and mannosylerythritol lipids), phospholipids; polyol lipids; lipoproteins, lipopeptides, ornithine lipids, carbohydrate-lipids, neutral lipids, aminoacid lipids, exolipids, liposan; siderolipids, protein polyamines diglycosyl diglycerides, fimbriae, saponified triglycerides and fatty acids. The composition may also contain a corrosion inhibitor intensifier.
