Implication

Numerical simulation uncovers improved gas recovery in hydrate reservoirs through hydraulic fracturing and thermal stimulation, suggesting operational optimizations.

Key Points

This research aims to enhance gas recovery from low-permeability hydrate reservoirs using a combined hydraulic fracturing and thermal stimulation approach.
Developed a numerical simulator using the embedded discrete fracture model (EDFM)
Analyzed coupled thermo-hydromechanical processes and multiphase flow dynamics during thermal recovery
Investigated optimal parameters for fracture networks and operational injection/production
Asymmetric conductivity profiles improve injection/production balance compared to symmetrical designs
Optimal well spacing of 70–90 m maximizes reservoir efficiency while reducing water breakthrough
Moderately deviated fracture geometries increase thermal front propagation uniformity
Water breakthrough can reduce daily gas output by 20% and total production by 10.12% by Day 100 when wells are fully connected
