Pressure transient survey in producer during the pressure fall period caused by opening well for production or increasing its production rate |
(see Fig. 1):
Interpretation of DD is based on:
Fig. 1. PTA Diagnostic Plot for vertical well in single-layer homogeneous reservoir with impermeable circle boundary (PSS). Pressure is in blue and log-derivative is in red. | Fig. 2. Pressure diffusion model fitting to pressure gauge data. Pressure is in blue and log-derivative is in red. |
