Abstract

Summary

Deposition of calcium carbonate and calcium sulfate mineral scales is the major problem encountering to the oil industry. Indeed, these salts exist and co-precipitate in the system of seawater injection for the purpose of EOR. For a long time, scale adhesion has been a matter of much attention. Instead of difficult scale removal, it seems that scale inhibition can be a suitable alternative, as prevention is better than cure! This paper investigates the inhibition efficiency of calcium carbonate and calcium sulfate through two distinct green scale inhibitors (SI), (A) and (B). The experimental results acclaim that (A) has high efficiency on both calcium sulfate and calcium carbonate, though (B) has more significant inhibition efficiency on calcium carbonate compared to calcium sulfate, at the similar condition of green SI dosage. Obtained scales were analyzed by filtration gravimetrical method as well as X-Ray diffraction (XRD). As it can be drawn from XRD, nearly 80% calcite and 60% gypsum would be inhibited in the absence of SI (A) using the dosage of 300 mg/L. Besides, the SI (B) inhibits 20% calcite and 10% gypsum. To sum up, more SI (B) would be required.
