Rapid analytical framework reconstructs formation pressure in fractured-vuggy reservoirs, suggesting a novel screening tool.

To develop an analytical framework for reconstructing formation pressure distributions in fractured-vuggy carbonate reservoirs.
Developed pressure-flow relationships for caves and fractures.
Combined unit-source solutions using spatial superposition and Duhamel convolution.
Evaluated the framework by comparing analytical results from Well EX-1 against PEBI-grid simulation.
Mean absolute error between analytical and PEBI pressures was 0.070 MPa.
Root-mean-square error was recorded at 0.083 MPa.
Maximum absolute error reached 0.13 MPa in the EX-1 case.

Li et al. (2026) studied this question.
