Abstract

Optimizing chemical reagents for paraffin deposit control is essential for improving oil production efficiency. This study presents a comparative analysis of three solvents: a volatile commercial reagent, a novel in-house formulation, and a commercial aromatic-based product. Their performance was evaluated based on dissolution kinetics and effectiveness against both standard paraffin and actual field deposits using complementary testing methodologies.

The results revealed substantial differences in solvent behavior. The in-house developed reagent demonstrated superior performance, achieving high efficiency rapidly for complex deposits. While the commercial aromatic-based product eventually reached comparable ultimate efficiency, it exhibited significantly slower dissolution kinetics with a noticeable induction period. The third commercial reagent showed considerably lower overall effectiveness.

Technical and regulatory assessment identified further limitations of the commercial aromatic-based product, including reliance on expensive imported components and absence of key performance parameters in its specifications. Although possessing certain advantageous properties like low corrosivity, its slow action and regulatory concerns limit practical applicability. Consequently, the proprietary in-house developed reagent emerges as the most promising candidate, warranting further investigation and development for oilfield applications.
