...-to-fracture and stage-to-stage stress shadow, (d) heterogeneity of stress, and (e) perforation erosion. In addition, practical causes of non-ideality must be considered: (a) random variability in perforation phasing and diameter, (b) perforation diameter dependence on phasing, (c) perforation plugging, and (d...

... to an exponent, β = 0.5 ( Weijers et al. 2000 ), and the final perforation diameter is equal to the nominal diameter. Using SDTs conducted in wells with bottomhole pressure (BHP) gauge data and DAS/DTS, Mondal et al. (2019) showed that β can vary between 0.25 and 1. Assuming a fixed value of 0.5 typically...
