Abstract:
A cementing method includes positioning a bottom plug at a casing shoe, rupturing the bottom plug, signaling when a top plug reaches a target position, and releasing a chemical into a cement slurry below the top plug in response to the signaling. The signal may comprise a mechanical trigger changing its position due to movement of the top plug past the target position.
