    Abstract: A method of treating a subterranean formation penetrated by a wellbore comprises: introducing into the subterranean formation a treatment fluid comprising a carbonate producing agent, urea, and a cation source; allowing a carbonate precipitate to form, the carbonate precipitate comprising a cation from the cation source and having a water solubility of less than about 0.1 g/100 mL at 25° C. and atmospheric pressure; and reducing or substantially preventing the passage of formation particles from the subterranean formation into the wellbore while allowing passage of formation fluids from the subterranean formation into the wellbore.

    Abstract: 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.
