Sustains productivity after secondary hydrate
Targeting permeability reduction caused by secondary hydrate formation during gas hydrate production, this gravel pack optimizes the size ratio to sustain horizontal well productivity even when saturation exceeds 0.79, extending production time.

Productivity ratio clearly declines when size ratio α = 4 and saturation > 0.79
For long-term production, size ratio α = 10 is better
Error comparison shows the new model predicts permeability changes more accurately
