Product Description

OCL-JSN is a sulfonated polymer fluid loss reducer that combines strong shale inhibition, excellent salt resistance, and high-temperature stability. It is a water-soluble polymer synthesized by copolymerizing AMPS and AM monomers.

Characteristics

Excellent shale inhibition performance;

Effective fluid loss reduction with outstanding resistance to saturated brine and temperatures above 160 °C;

Good compatibility, simple on-site application process, easy maintenance, low treatment dosage, and cost-effective drilling fluid performance. The optimal dosage is 1–2%.
