Claim 11:
12. A method comprising:
placing casing within a subterranean well;
providing a cement slurry comprising water, a hydraulic cement, oil-absorbent particles, and non-swellable hydrophobic fibers having a length between 500 μm and 20 mm, and a diameter between 100 nm and 1 mm within the subterranean well,
wherein the oil-absorbent particles are elongated, having an aspect ratio between 15 and 1000 before swelling, and between 5 and 350 after swelling, and
wherein the oil-absorbent particles contact a non-aqueous component of residual drilling fluid on the casing and formation surfaces of the subterranean well to decrease a property of flowability of the non-aqueous component of the residual drilling fluid.
