It was developed for use in oil production stimulation processes for acid treatment of producing oil and gas wells.
This additive can be used in most of the water-based acid solutions and in mineralized mediums, to be injected directly to the process cycle and does not require special process equipment. Recommended efficient concentration in the acid compound systems is about 5 l per 1 m3, depending on the required result, which affected by the factors like: solution pH and acid composition, crosslinking rate and required compound viscosity.
ability to treat the solution without use of special process equipment
highly soluble in water without use of special-purpose equipment
dilution time is no more than 10-15 minutes
upon injection, creates temporary viscoelastic barrier which deflects “fresh” acid to the untreated low-permeability portions
upon acid reaction in the reservoir, the compound is mixed with apparent viscosity of more than 16,000 cP
upon completion of acid treatment, the barrier is destroyed upon reaching pH 4-5, facilitating further well stimulation
