1. A method for cementing a subterranean well, comprising:
placing 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 a drilling fluid within the subterranean well and decrease a property of flowability of the non-aqueous component of the drilling fluid.
