Water Intrusion Characterization in Naturally Fractured Gas Reservoir
Based on Spatial DFN Connectivity Analysis
The non-intrusive EDFM (embedded discrete fracture model) in combination
with Oda method are employed to characterize natural fracture networks.
Initially, full field model, and the pressure and water breakthrough of
all the producing wells were matched to evaluate production forecasts.
As presented, wellbore connectivity to the fracture network has a
considerable effect on characterizing the water intrusion in fractured
gas reservoir. Also, dominant water flow paths within the fracture
network aid to understand and predict the water intrusion phenomena.
Therefore, fracture clustering as shortest paths from the water contacts
to the wellbore endorses the results of the numerical simulation.
Finally, matching the breakthrough time depends on merging responses
from multiple dominant water flow paths within the distributions of
fracture network. This study is crucial to field modeling and the
decision-making process of wells operation by anticipating water
intrusion behavior through probable flow paths within the fracture
