Based on the experience and
Scaling is therefore required. The flow capacity (kh) value from pressure build-up analysis as the basis to upscale permeability from core to field drainage area was used. The permeability distribution from core-trained LLNFM was used as the base parameter in order to identify the heterogeneity (seen by core data versus pressure transient data). Then, the flow capacity values from DST analysis were mapped for each formation (K1, K2, K3, and K4).
