Organoclay for High Temperature Drilling Mud
High temperature drilling environments place extreme demands on the rheological stability of oil-based drilling fluids. Under elevated temperature and pressure, conventional viscosifiers often lose structure, leading to poor cuttings suspension, unstable viscosity, and increased risk of sagging or settling of weighting materials.
CAMP-SHINNING CP-992 Organoclay is specifically engineered as a high-efficiency rheology modifier for oil-based and synthetic drilling mud systems operating under high temperature conditions. Manufactured through an advanced wet modification process, CP-992 delivers rapid dispersion and strong gel development even in low aromatic and environmentally sensitive base oils.
It performs exceptionally well in:
-
Diesel oil systems
-
Crude oil mud
-
Low BTEX base oils
-
Mineral oil drilling fluids
-
Synthetic-based mud formulations
By forming a robust three-dimensional network within non-aqueous fluids, CP-992 significantly enhances viscosity, yield point, and suspension stability, ensuring reliable mud performance during deep and high-temperature drilling operations.

FAQ (For Drilling Fluid Users)
Q1: What type of drilling fluids is CP-992 suitable for?
A: It is designed for oil-based and synthetic-based drilling mud, especially low aromatic systems.
Q2: Can CP-992 be used in high temperature wells?
A: Yes. It remains rheologically stable up to 230℃ under high pressure.
Q3: What is the main function of CP-992 in drilling mud?
A: It acts as a viscosifier and gelling agent to improve suspension, gel strength, and emulsion stability.
Q4: Does CP-992 help prevent barite sag?
A: Yes. Its strong thixotropic network effectively suspends weighting materials.
Q5: Is high shear required for dispersion?
A: No. CP-992 disperses quickly with relatively low shear compared to conventional organoclay.
