| titleOfInvention | Sulfur-containing polyether surfactants for cement spacer fluids and other downhole applications |
| abstract | Spacer fluid compositions comprising water, clay, and sulfur-containing polyether surfactants are disclosed, and such compositions typically may further include weighting additives, antifoam additives, and co-solvents. These spacer fluid compositions can be used to treat metal casing and remove drilling fluid residues for improved cement bond in wellbore applications. |
