Curing time

Fulcrum cement-conveyed frac performance technology modifies the rheology of nonaqueous drilling fluid (NAF) in channels next to the cement. To quantify the rheology change, scientists prepared vials containing 15-mL slurries of conventional cement and the same cement with Fulcrum technology, added 2 mL of diesel-based drilling fluid, and allowed the samples to set at a common downhole temperature. After 6 days, the vials were opened and the yield points of the drilling fluids measured.
