buildup test

1. n. [Well Testing]

The measurement and analysis of (usually) bottomhole pressure data acquired after a producing well is shut in. Buildup tests are the preferred means to determine well flow capacity, permeability thickness, skin effect, and other information. Soon after a well is shut in, the fluid in the wellbore usually reaches a somewhat quiescent state in which bottomhole pressure rises smoothly and is easily measured. This allows interpretable test results.
