    Abstract: The present invention relates to a method of dewatering an aqueous mineral suspension comprising introducing into the suspension a flocculating system comprising a poly(ethylene oxide) copolymer, in particular a copolymer of ethylene oxide and one or more epoxy or glycidyl ether functionalized hydrophobic monomer. Said poly(ethylene oxide) copolymers are useful for the treatment of suspensions of particulate material, especially waste mineral slurries. The invention is particularly suitable for the treatment of tailings and other waste material resulting from mineral processing, in particular, the processing of oil sands tailings.

    Abstract: The hydration of clays and shale in drilling operations may be inhibited by employing an aqueous based drilling fluid comprising a shale hydration inhibition agent having the formula: (Formula I should be inserted here.) wherein R is hydrogen or an alkyl group having 1 to 12 carbons, R1 is an alkylene group having 1 to 12 carbons, and R2 is an alkyl group having 1 to 12 carbons. The shale hydration inhibition agent should be present in the aqueous based drilling fluid in sufficient concentration to reduce the reactivity, such as swelling, of clays and shale when exposed to water-based drilling fluids.

    Abstract: The hydration of clays and shale in drilling operations may be inhibited by employing an aqueous based drilling fluid comprising a shale hydration inhibition agent having the formula wherein R is an alkyl group having 1 to 6 carbons, R1 is an alkyl group having 1 to 18 carbons, and X is an anion. The shale hydration inhibition agent should be present in the aqueous based drilling fluid in sufficient concentration to reduce the reactivity, such as swelling, of clays and shale when exposed to water-based drilling fluids.
