Overview

Prevents sludge formation in crude oil mixtures during acidic treatment thereby increasing drilling operation efficiency and output.

Product description

RXSOL Anti Sludge AS 180 is a high-performance anionic surfactant package specifically formulated to prevent the formation of asphaltic sludge during hydrochloric acid (HCl) stimulation treatments. The product stabilizes crude oil asphaltenes, minimizes sludge precipitation, and improves acid penetration into the formation.
 
By preventing acid/crude incompatibility, the additive enhances treatment efficiency, reduces formation damage, and promotes rapid flowback after acidizing operations.

Applications

Where is Anti Sludge AS 180 used?

Main application is for preventing asphalt sludge during HCL Hydrochloric Acid Treatment

  • Matrix acidizing
  • Carbonate reservoir stimulation
  • Sandstone acid treatments
  • Well cleanup operations
  • Production enhancement treatments
  • High-asphaltene crude oil reservoirs
  • HCl acid systems
  • Organic acid systems (formic/acetic acid blends)

Where it is used

Why is there SLUDGE formation during drilling operations and how to CONTROL SLUDGE FORMATION?

Sludge formation commonly occurs due to the interaction between crude oil, drilling fluids, acids, and contaminants, leading to blockages, reduced permeability, and operational inefficiencies. Anti Sludge Agents are designed to inhibit these reactions and ensure smooth fluid flow during drilling, completion, and stimulation processes.

In applications such as acidizing and well stimulation, sludge formation can severely impact treatment effectiveness and formation productivity. Anti Sludge Agents work by stabilizing asphaltenes and dispersing heavy organic compounds, preventing their aggregation and deposition. This ensures that fluids remain clean and free-flowing, allowing efficient penetration into the formation. The product is compatible with various oilfield fluid systems and performs reliably across a wide range of temperatures, salinity levels, and reservoir conditions.

Dosage

Mix RXSOL Anti Sludge AS 180 with acid and crude oil solution depending on the sludge properties of each. Usual dosage is 8-30 Ltrs of Anti Sludge AS 180 per 1000 Ltrs solution.

Important Consideration: DO NOT MIX with solutions containing cationic elements (corrosion inhibitors, etc). This would result in an internal chemical reaction.

Notes

How to prevent sludge formation during acidic treatment in oilfield application?

It is critical to prevent sludge formation in oil operations. This increases operational efficiencies in the long run. Reduce clean up time and increase oil-production after stimulation using RXSOL Anti Sludge AS 180:

  • Prevents asphaltic sludge formation during acidizing
  • Stabilizes dispersed asphaltenes
  • Minimizes acid/oil incompatibility
  • Prevents emulsion formation
  • Improves acid penetration into the formation
  • Reduces formation plugging
  • Enhances permeability recovery
  • Improves post-treatment flowback
  • Compatible with most acid corrosion inhibitor packages
  • Effective over a wide temperature range

Remarks

  • Prevents sludge formation when hydrocarbons react with acids.

  • Enhances wetting properties for better interaction with formation materials.

  • Suitable for both sandstone and carbonate acidizing.

  • Supports smoother acid stimulation operations by eliminating sludge-related challenges.
