- Can PAC filtration control agent be used in salt water?
- It is suitable for use in fresh water, salt water and brine-based fluids. PAC-R filtration control agent is stable to 300°F (149°C), non-toxic and does not require a biocide. PAC filtration control agent products are premium quality fluid loss control products providing superior performance to most other products in their class.
- What is Pac filtration control agent?
- PAC filtration control agent products are premium quality fluid loss control products providing superior performance to most other products in their class. PAC-R filtration control agent exceeds the European specifications for regular viscosity polyanionic cellulose. Effective in fresh water, salt water, and brine-based fluids.
- Does PAC affect drilling fluid viscosity and filtrate volume?
- A. G. Iscan et al. investigated the effect on viscosity and filtrate volume by varying the amount of PAC added to the drilling fluid and found that drilling fluid viscosity increased with increasing, but non-linear, PAC content.
- Why do we use nanoparticles in Pac based drilling fluid?
- The small size and unique nature of nanoparticles allow them to penetrate into the thin layers of the formation and prevent further seepage of water into the formation, hence further reducing the filtration loss of the PAC based drilling fluid.
