Design and Evaluation of a CO2-Responsive Fracturing Fluid for Coalbed Methane Recovery
This study focuses on constructing a CO2-responsive and low-residue fracturing fluid tailored for coalbed methane (CBM) extraction, aiming to overcome the issues of poor flowback and high residue commonly observed in traditional systems. A novel tertiary amine-based surfactant (HDD) was synthesized via a nucleophilic s...
