Unlocking Methane Recovery Efficiency
AI-Driven Optimization of Sealing Materials for Enhanced Grouting Operations
Executive Summary: AI-Enhanced Methane Recovery
This study pioneers an AI-driven framework for optimizing fracture sealing materials (FSMs) in coalbed methane (CBM) recovery. Addressing the critical challenge of gas leakage in fractured strata, the framework integrates predictive modeling, multi-objective optimization, and multi-criteria decision-making. By leveraging advanced machine learning (MLPNN models tuned with GA and PSO) and genetic algorithms (NSGA-III), it identifies Pareto-optimal FSM compositions that balance pumpability, mechanical strength, gel time, and expansion rate. The VIKOR method further refines selection, offering tailored solutions for diverse operational needs. This approach significantly reduces reliance on traditional, costly experimental methods, accelerating the development of highly adaptable and efficient sealants for complex underground environments, ultimately enhancing long-term CBM extraction and safety.

Key Material Properties Optimized
The optimization focused on critical FSM performance indicators: Apparent Viscosity (AV) for injectability, Compressive Strength (CS) for mechanical integrity, Gel Time (GT) for controlled curing, and Expansion Rate (ER) for fracture filling. These properties are crucial for long-term sealing effectiveness in CBM recovery.

Pareto-Optimal Solutions & Trade-offs
The NSGA-III algorithm identified diverse Pareto-optimal FSM compositions, highlighting critical trade-offs. For instance, high compressive strength formulations (≈ 4.9 MPa) often exhibit higher apparent viscosity (≈ 305 mPa·s), potentially limiting injectability. Conversely, lower-viscosity formulations (AV < 180 mPa·s) offer better injectability but with moderate compressive strength (≈ 3–4 MPa). The VIKOR multi-criteria analysis further refined these, providing tailored compromise solutions for various operational needs, from pumpable deep injections to high-strength, fast-setting systems.
Real-World Application Example
Example Scenario: A scenario prioritizing low viscosity and high gel time resulted in an AV of 134.5 mPa·s and GT of 53.75 min, ideal for deep seam grouting where penetration is key. Another prioritizing high CS and ER yielded AV of 304.6 mPa·s, CS of 4.9 MPa, and ER of 7.95%, suitable for highly fractured, high-stress zones.
Key Takeaway: AI-driven optimization enables a systematic balance of competing objectives, delivering adaptable sealants for complex underground environments.
