Randomized trial evaluates flow baffling due to faults in high-permeability reservoirs, suggesting a new diagnostic approach.

To develop a field-constrained pressure-transient workflow to diagnose fault-related flow baffling in reservoir systems.
Developed a pressure-transient workflow utilizing numerical models and defined a leakage coefficient (Lf).
Benchmarking against KAPPA Saphir to assess pressure-derivative responses and drawdown characteristics.
Analyzed data from three anonymized long horizontal wells with different fault behaviors.
Average errors of 9.66% for the pressure derivative and 10.36% for pressure drawdown were observed in the model comparisons.
Well B exhibited a broadened transitional anomaly with Ih*=0.61 and th=27.17 h, indicating specific fault impacts.
Diagnosis of faults involved understanding the complex relationship between derivative characteristics and geological context.

Xiao et al. (2026) studied this question.
