Total water requirement per sack of cement for drilling, particularly in oil and gas well cementing, varies depending on the type of cement, additives, and desired slurry density. In drilling operations, cement slurries are designed to meet specific conditions, such as depth, temperature, and pressure, so the water requirement is calculated based on the cement class and the formulation provided in the cementing program.
