Aquative-600®

Anti-sludge agent

Description

Aquative-600 is a blend of an anionic dispersant, a glycol and selected alcohols designed to minimize asphaltene precipitation in acid stimulation applications.

Application

Aquative-600 anti-sludge additive is specifically designed to minimize the destabilization of the asphaltene colloidal dispersion when contacted by acid during a stimulation job. This product is a balanced, multipurpose package formulated with anti-sludge, corrosion inhibitor and non-emulsifier components.

Features and Benefits
  • Multi-functional - One product package eliminates the need to handle, measure and blend several chemicals
  • Compatible - Single package eliminates concern over potential side-effect problems with multiple chemicals
  • Economical - Designed to optimize the cost performance of each individual component
  • Low pour point - Product can be used year-round, even in the coldest weather; no need for heated storage or dilution

Aquative-820®

Iron control agent for acidizing

Description

Aquative-820 is a specifically formulated, liquid iron sequestering agent developed to alleviate the precipitation of hydrous ferric oxide during acidizing operations.

Application

Aquative-820 readily forms water soluble complexes with the released ferric ions thus preventing or significantly reducing the precipitation of hydrous ferric oxide as the pH of the acidizing fluid rises above 2.0 as the acid spends on the formation.

Features and Benefits
  • Prevents the destabilization of the colloidal dispersion
  • Minimizes or eliminates asphaltene sludge formation
  • Reduces the potential for formation damage
  • Completely soluble in most acidizing fluids
  • Effective at application temperatures up to 200 °F

ASCAV-120®

Oxygen scavenger

Description

ASCAV-120 liquid oxygen scavenger reacts with oxygen dissolved in water to mitigate its corrosive effects on carbon steel.

Application

ABC-140 is recommended for use in controlling bacteria, including sulfate-reducing bacteria and general aerobic bacteria. This includes microorganisms that contribute to biofilm formation in oilfield recovery, processing, and transportation applications. Applications include waterfloods, water holding tanks, disposal well water, packer fluids, recirculating water handling systems and pipelines.

Features and Benefits
  • Minimizes the impact of oxygen related corrosion
  • Can be used to minimize the impact of chlorine on nanofiltration membranes
  • Will not poison nanofiltration membranes in sulfate reduction plants
