摘要:
Hydrogen sulfide and mercaptans may be catalytically removed from a fluid stream by introducing to the fluid stream a sulfide quinone reductase (SQR) enzyme.
摘要:
Cements, such as alkali activated aluminosilicate, may be used as coatings on proppants, such as brown sand and white sand, to improve the strength thereof. The resulting coated proppants show increased strength as well as produced fines of lower than about 10 wt % at 10,000 psi closure stress.
摘要:
Antifreeze proteins having an ice-binding site, such as those derived from the Marinomonas primoryensis bacterium, may be used in additive compositions, fluid compositions, and methods for depressing the freezing point of the fluid compositions. The fluid composition may include the antifreeze protein and a base fluid, such as drilling fluids, servicing fluids, production fluids, completion fluids, injection fluids, refinery fluids, and combinations thereof.
摘要:
Disclosed herein is a fracturing fluid comprising a carrier fluid; a polymer that is soluble in the carrier fluid; the polymer being a synthetic polymer; the synthetic polymer being operative to increase the viscosity of the carrier fluid to about 5 to about 50 centipoise; the fracturing fluid being operative to reduce friction during a downhole fracturing operation and to transport a proppant during the downhole fracturing operation.
