摘要： A nanosilica containing fluid system for shale stabilization in a shale formation. The nanosilica containing fluid system comprising a functionalized nanosilica composition operable to react with shale at the surface of the shale formation to form a barrier on the shale formation. The functionalized nanosilica composition comprising a nanosilica particle, the nanosilica particle having a mean diameter, and a functionalization compound, the functionalization compound appended to the surface of the nanosilica particle. And an aqueous-based fluid, the aqueous-based fluid operable to carry the functionalized nanosilica composition into the shale formation. The functionalization compound is an amino silane. The aqueous-based fluid is selected from the group consisting of water, deionized water, sea water, brine, and combinations thereof.

摘要： A cement bond test cell includes an outer cylinder and an inner cylinder coaxially disposed within the outer cylinder along a central axis. The inner cylinder defines an inner volume configured to be filled with a fluid. An annulus is formed between the outer cylinder and the inner cylinder and configured to be filled with a test cement. The cement bond test cell further includes an acoustic transmitter disposed within the inner volume and configured to be acoustically coupled to an interior surface of the inner cylinder by the fluid. The cement bond test cell further includes at least one acoustic receiver acoustically coupled to an exterior surface of the outer cylinder.
