Abstract

A laboratory-to-practical validation study was conducted for a K-PAC–CMC composite stabilizer derived from rice-straw and natural-fiber textile-waste cellulose. Four formulations (C1–C4) were compared using moisture, active-matter content, water solubility, pH, water-return index and degree of polymerization (DP). C4 showed 5% moisture, 83% active matter, 98.8% solubility, a water-return index of 3.2 cm³/min and DP=1050. Relative to C1, water return decreased by 23.8% and DP increased by 56.7%. An equal-weight min–max multi-criteria index ranked C4 first (ISI=1.000). FTIR supported cellulose-ether/carboxyl functionalization, while dissertation TGA/XRD data provided complementary thermal and amorphous–crystalline evidence. The formulations were also evaluated under 120–150 °C thermal/geological-model conditions. A 2024 certificate and trial act issued by the Shurtan Oil and Gas Production Department document experimental application and recommendation for production implementation. A technological circuit combining preparation, circulation, solids separation and parallel rheology/API/HPHT/aging/shale-control modules is presented; HPHT is explicitly treated as a subsequent standard-qualification module rather than as historical measured data. The combined evidence identifies C4 as the most balanced formulation and establishes a technically defensible basis for further ISO/API qualification and scale-up.
