EcoAcid® - Single-phase Retarded Acids for Carbonate Stimulation

Typical Properties and Field Applications

EcoAcid technology has been fully developed for field applications. It has been proved to be effective in treatment of carbonate reservoirs by the comprehensive laboratory studies at the following conditions:

Temperature:
BHST 125‑325°F (51‑163°C)
Formation:
Carbonate formation
Treatment fluids:
Single phase (aqueous) retarded acids
Further information about field applications is described in documented “Case History of EcoAcid Technology”.

Precautions and HSE Considerations

The retarding agents KMA026A and KMA026B in EcoAcid systems play the most important role in provision of retardation kinetics, stimulation effectiveness and operational simplicity. Corrosion inhibitor KMA044, iron control agent KMA033 and flowback surfactant KMA001S are generally used to prevent acid corrosion on tubulars and iron precipitation in the wellbore or formation. H2S scavenger KMA009B is compatible with other additives and used in EcoAcid systems if H2S scavenger is required.

The laboratory procedures, quality assurance program and guidelines for field mixing and handling of EcoAcid systems are described in EcoAcid fluid manual.
