摘要： A novel method and device for manipulating ferrofluids for use in cementing wells are disclosed. The cementitious fluids may comprise: (a) a hydraulic cement, (b) finely divided magnetic particles, (c) a binding agent or a surfactant, and (d) a liquid medium. The binding agent or surfactant is present in the compositions in an amount sufficient to render the compositions stable in a magnetic field. When used in cementing wells, the cementitious ferrofluids are implaced in the annulus separating a casing from the formation in a wellbore by conventional techniques and the slurry is subsequently subjected to an activating alternating magnetic field that causes movement of the flurry. The non-cementitious ferrofluids comprise: (a) finely divided magnetic particles, (b) stabilizing agent, and (c) a liquid medium. The movement of the slurry results in a "scrubbing" action against the surface of the casing and formation surfaces, and a mixing of the slurry which helps displace any residual drilling mud. The net result is better bonding of the cement to the casing and formation.

摘要： A method of marring a fiber optic substrate by directing a water jet abrasive slurry at the substrate while causing relative movement between an elongate support for the substrate and the water jet abrasive slurry to produce a marring pattern on the substrate. The pressure of the water jet abrasive slurry and/or the rate of relative movement between the elongate support and the water jet abrasive slurry may be varied to produce a variable marring pattern on the substrate.
