1. A method comprising:
providing a pipe string extending through a wellhead and into a wellbore, wherein an annulus is formed between the pipe string and the wellbore;
closing, with an isolation device, the wellbore in a closed pressure loop;
introducing a cement composition for a reverse cementing process to an interior of the pipe string;
diverting, with a crossover tool, the cement composition from the interior of the pipe string to the annulus;
measuring, with a pressure sensor, pressure of the interior of the pipe string at the crossover tool; and
based at least partly on the measured pressure of the interior of the pipe string at the crossover tool, manipulating fluid flow through an outlet port of the wellhead using a choke valve to maintain an equivalent circulating density of fluids in the wellbore between a pore pressure of a subterranean formation into which the wellbore is formed and a fracture gradient of the subterranean formation.
