Effectiveness of fluid loss additives in laboratory dynamic fluid loss experiments
- Louisiana Tech Univ., Ruston, LA (United States)
A commercially available HTHP (high temperature, high pressure) dynamic filtration unit and a widely available HTHP rheometer was used to study dynamic fluid-loss behavior of uncrosslinked hydroxypropyl guar hydraulic fracturing fluid containing varying concentrations of silica flour, starch, and diesel. New dimensionless groups were defined for the dynamic fluid-loss problem. These groups were used first to effectively correlate previously reported laboratory data and later were employed to analyze the ensuing experimental data. Results demonstrate that low and high permeability cores require different mechanisms for fluid-loss control and that, compared to silica flour, starch may lose its effectiveness at higher concentrations.
