China UBDrill Shale Inhibitors 131 & 132 - Top Suppliers & Factory for Enhanced Shale Inhibition Solutions
Product Introduction
- ▲ Provides excellent shale inhibition
- ▲ Limits cuttings dispersion
- ▲ Reduces accretion potential, minimizing bit and BHA balling
- ▲ Ensures environmental acceptability for both on shore and onshore applications
UBDrill-131
- UBDrill-131 shale inhibitor is a low-molecular-weight polymer blended liquid containing povidone & polyamine derivative to provide superior inhibition of reactive clay and reduce swelling of sensitive shales exposed to water-based drilling fluids.
- UBDrill-131 is the primary shale inhibitor of polyamine high-performance water-based drilling fluid system. It acts as a clay hydration suppressant by intercalating and reducing the space between clay platelets so that water molecules will not penetrate and cause shale swelling.
- UBDrill-131 can also flocculate any dispersed clays or colloidal particles and aids their removal by solids control equipment to achieve shear-thinning properties. UBDrill-131 is suitable in fresh water, seawater and monovalent brines up to 300°F.
UBDrill-132
- UBDrill-132 shale inhibitor is a blended liquid containing polypropylene glycol & poly ether amine acetate to provide superior inhibition of reactive clay and reduce swelling of sensitive shales exposed to water-based drilling fluids.
- UBDrill-132 is the primary shale inhibitor of polypropylene glycol high-performance water-based drilling fluid system. It acts as a clay hydration suppressant by intercalating and reducing the space between clay platelets so that water molecules will not penetrate and cause shale swelling.
- UBDrill-132 can undergo ion exchange reactions with metal ions such as sodium or potassium on the surface of clay particles and inhibiting the hydration and expansion of clay.

How to Choose the Right Shale Inhibitor?
Selecting the right shale inhibitor involves balancing drilling objectives, geological conditions, drilling fluid systems, and operational constraints. Here are the specific steps and considerations:
01
Define Drilling Objectives
02
Assess Geological Conditions
03
Match the Drilling Fluid System

Differences in Shale Inhibitors Across Operations
▲ Drilling
Focuses on real-time shale inhibition and ROP enhancement, requiring potent, easily dispersible inhibitors (e.g., UltraHib Plus).
▲ Cementing
Targets cement slurry filtrate effects on shale, needing short-term, efficient inhibitors (e.g., amines or polymers).
▲ Workover
Prevents fluid invasion into shale during temporary operations, requiring low-invasion, removable inhibitors (e.g., polyamines).
To distinguish shale inhibitors, evaluate their chemical makeup, mechanisms, and properties. For selection, consider drilling goals, geological conditions, fluid systems, and economics, supported by testing. Our products suit high-performance needs, and eco-friendly meet regulatory demands. Tailor the choice to specific well conditions for optimal inhibition and operational efficiency.
Frequently Asked Questions (FAQ)
Q:
What is the primary function of UBDrill-131 and UBDrill-132?
Both are high-performance shale inhibitors designed for water-based drilling fluids. They suppress clay hydration and reduce the swelling of sensitive shales by intercalating and reducing spacing between clay platelets.
Q:
What are the temperature limitations for these shale inhibitors?
Both UBDrill-131 and UBDrill-132 are temperature stable up to 300°F. However, they can achieve higher temperature limits if used in conjunction with oxygen scavengers.
Q:
What is the recommended treatment volume for UBDrill-131 and UBDrill-132?
The typical recommended treatment range for UBDrill-131 is 1.5% to 3.0% by volume. For UBDrill-132, the typical treatment range is 1.0% to 2.0% by volume.
Q:
Are these products environmentally acceptable?
Yes, both UBDrill-131 and UBDrill-132 are designed to ensure environmental acceptability for both onshore and offshore drilling applications.
Q:
How do UBDrill-131 and UBDrill-132 differ in their chemical composition?
UBDrill-131 is a low-molecular-weight polymer blended liquid containing povidone and polyamine derivatives, whereas UBDrill-132 is a blended liquid containing polypropylene glycol and polyether amine acetate.
Q:
What packaging options are available for these shale inhibitors?
Both products are packaged and supplied in 55-gallon drums and 275-gallon IBC totes.
