Abstract
Preventing the flow of soil grains into oil and gas wells is highly desirable for the protection of hydrocarbon production. Geotechnical engineering solutions addressing this issue may utilize enzyme-induced precipitation methods to consolidate and increase shear strength. Methods may comprise: providing a mixture comprising urea, a urease enzyme, calcium chloride, magnesium chloride, and a cellulose; contacting at least a portion of the mixture with at least a portion of a subterranean formation; and forming a biomineral precipitate within the subterranean formation. The biomineral precipitate, comprised of a carbonate mineral and an evaporite mineral, may consolidate particles within the subterranean formation to form a consolidated body.
