China OBM Rheology Viscosifier UBDrill-242: Top Suppliers & Factory for High-Performance Oil-Based Mud
Product Introduction
UBDrill-242 is a polymeric material acting as rheology modifier for oil-base mud.
※ UBDrill-242 is a polymeric rheology modifier designed for oil-based drilling fluid (OBM) systems. It is primarily used to enhance low-shear-rate viscosity (LSRV) and yield point (YP) of invert emulsion systems while maintaining a minimal impact on plastic viscosity (PV).
※ The product is engineered to improve low-end rheology and suspension capacity without significantly affecting other key mud properties such as emulsion stability and HTHP fluid loss. It is fully compatible with standard oil-based mud additives used in modern drilling fluid systems.

Applications / Functions
- High-performance oil-based drilling fluid systems (OBM / SBM)
- Deep and high-temperature drilling operations
- Weighted mud systems requiring improved suspension stability
- Wells prone to barite sag or poor solids transport
- Extended static or long-reach drilling sections
Recommended Handling
A typical dosage is according to the ratio of water/oil and density of OBM, but a pilot test is required for optimal results.
All personnel handling this material must handle it as an industrial chemical, wearing protective equipment and observing the precautions as described in the Material Safety Data Sheet (MSDS).
Packaging and Storage
- 200L/Drum
- Store in dry, well-ventilated area. Keep container closed. Keep away from heat, sparks and flames. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping and /or stacking.
Frequently Asked Questions
What is UBDrill-242 used for in drilling operations?
UBDrill-242 is a polymeric rheology modifier designed for oil-based drilling fluid (OBM) systems. It enhances low-shear-rate viscosity (LSRV) and yield point (YP) while maintaining minimal impact on plastic viscosity (PV).
Does UBDrill-242 affect emulsion stability or HTHP fluid loss?
No. UBDrill-242 improves low-end rheology and suspension capacity without significantly affecting key mud properties like emulsion stability and HTHP fluid loss.
What are the physical properties of UBDrill-242?
It has a flash point of > 75℃, a pour point of < -5℃, a specific gravity of 0.85 ~ 0.96 at 20℃, and has a slight mineral oil odor.
How should UBDrill-242 be dosed?
The typical dosage depends on the water/oil ratio and the density of the OBM. A pilot test is highly recommended to determine the optimal dosage.
What are the packaging and storage requirements?
UBDrill-242 is packaged in 200L drums. It must be stored in a dry, well-ventilated area with containers tightly closed, kept away from heat, sparks, open flames, and incompatible materials.
