Abstract
A method can include acquiring data via a receiver mounted in a drill string during tripping of the drill string downward into a wellbore (e.g., including a casing and a cement annulus about the casing) where the acquired data can be for evaluation of at least one characteristic of cement; buffering at least a portion of the acquired data to a memory device mounted in the drill string; and while pumping drilling fluid through a passage in the drill string, as disposed in the wellbore, transmitting at least a portion of the buffered data via mud-pulse telemetry.
