Diagnose and resolve oil-based mud issues. This comprehensive guide covers low ES, barite sag, HTHP fluid loss, and rheology instability solutions.

Experimental study of 2.04 g/cm³ oil-based drilling fluids under 200°C–232°C HPHT conditions. Evaluation includes rheology, electrical stability, HTHP fluid loss, drill solids contamination, and brine contamination resistance.

Learn how to prevent emulsion water separation and improve electrical stability in high-temperature, contaminated oil-based drilling fluids.

Learn how HTHP drilling fluid stability is maintained under extreme temperature and pressure. Explore failure mechanisms, testing methods, OBM/WBM design and optimization strategies.

Looking for high-performance OBM wetting agents? Learn how Unitech Chemicals wetting agents stabilizes drilling fluids, reduces costs, and prevents water-wet solids.

Learn the differences between primary and secondary emulsifiers in oil-based mud (OBM). Compare functions, ES performance, thermal stability, troubleshooting, and selection tips for high-performance drilling fluids.
