To reduce the operational cost and risk of conventional downhole testing, this study presents an integrated well-test interpretation workflow that uses wellhead shut-in pressure data to characterize formation flow conditions in real time. Fluid mass- and heat-transfer equations are established for the wellbore, and a h...

Large-scale caves provide important storage space in carbonate oil and gas reservoirs. However, accurately estimating their volume remains challenging because of complex geometries and limited access to underground cavities. In this study, an analytical well-test method is proposed to estimate large-scale cave volume f...
In this study, a rapid analytical framework is developed for reconstructing transient formation-pressure distributions in sparsely connected fractured-vuggy carbonate reservoirs using well-test-derived fracture–cave geometry and source allocation. Pressure–flow relationships are established for caves, fractured bodies,...
