It is suitable for both freshwater and saltwater mud systems commonly used in oil drilling operations.
Reduces fluid loss to formations by 40–60% compared to standard PAC, minimizing wellbore damage. This PAC significantly reduces API fluid loss in water-based drilling fluids, helping maintain stable mud properties during drilling operations. Improved filtration control protects the wellbore and minimizes formation damage
Adsorbs onto clay surfaces to prevent hydration and swelling, reducing the risk of stuck pipe in reactive formations.
Stabilizes long lateral sections by maintaining consistent fluid viscosity and reducing friction pressure.
Performs reliably in temperatures exceeding 150°C, critical for deep oil and gas exploration.
Resists flocculation in brine-based muds, ensuring performance in salt dome and evaporite formations.
Acts as a viscosity builder in low-solids completion fluids, facilitating effective well cleanup.
Q: How does High-Purity PAC interact with other drilling fluid additives?
A: It exhibits excellent compatibility with lignosulfonates, biocides, and weighting agents like barite, forming synergistic systems that enhance overall fluid performance.
Q: What dosage is recommended for optimal performance?
A: Typical addition rates range from 0.3–1.0 kg/m³ of drilling fluid, with higher concentrations (0.8–1.0 kg/m³) recommended for HPHT conditions.
Q:Can it withstand high-temperature drilling conditions?
Yes. The PAC maintains stable performance under elevated temperatures commonly encountered in oil and gas drilling operations.
Q: Can samples be provided before bulk purchase?
