DELAYED-EXPANSION CEMENT AND CEMENTING OPERATIONS
A delayed-expansion cement mixture or slurry of hydraulic cement contains an expanding agent having hydrophobically modified surfaces with a hydrophobic and/or self-assembling film. A method to delay expansion of cement involves treating the expanding agent with a self-assembling film precursor compound, making the slurry with cement and water, and setting and expanding the cement. A cementing method places the mixture or slurry downhole where it is hardened and expanded.
