1. A method comprising:
pumping cement into a conduit disposed in a borehole of a formation to displace a spacer fluid in the conduit and for placement of the spacer fluid in an annulus in the borehole disposed between the conduit and the formation;
acquiring sensor-based measurements during the pumping;
using the sensor-based measurements, controlling the pumping for turbulent flow of the cement in the annulus in the borehole disposed between the conduit and the formation; and
responsive to a transition to a deceleration phase of the cement, using the sensor-based measurements, controlling the pumping for laminar flow of the cement in the annulus.
