Fluid density is one of the key properties of any slurry designs, and directly affects the management of hydrostatic pressure of the fluid column. A cement slurry with a too low a density can result in a kick or even a blowout due to hydrostatic pressure failing to overcome formation pore pressures. However, a fluid with too high a density may result in damage to the formation if the hydrostatic pressure of the weighted fluid exceeds the fracture gradient, inducing fractures. Additionally, slurry properties such as compressive strength, viscosity, fluid loss and free water are influenced by density. These properties are directly correlated to quality barrier dependability required for wellbore integrity. Halliburton offers ore-derived and mined heavyweight additives with specific gravities ranging from 4.2 to 5.2.
