Abstract:
A downhole treatment composition comprises a rare earth-containing compound comprising one or more of the following: scandium; yttrium; lanthanum; cerium; praseodymium; neodymium; promethium; samarium; lutetium; europium; gadolinium; terbium; dysprosium; holmium; erbium; thulium; or ytterbium, wherein the downhole treatment composition is a cement slurry, a drilling fluid, or a spacer fluid. Also disclosed are methods of cementing a wellbore, methods of displacing a first fluid, and methods of drilling a wellbore in a subterranean formation using the cement slurry, the spacer fluid, or the drilling fluid.
