Buildup Pressure for a Field
Buildup pressure for a field is the pressure recorded at the bottom of a wellbore during a shut-in period after a flow test or during a well control event. It is typically measured in oil and gas fields to evaluate reservoir properties, well performance, or the effectiveness of pressure control measures during drilling operations.

| \( \rho_{ws} \) (Greek symbol rho) = Shut in Pressure (psi) | - | \(Pa\) |
| \( m \) = Slope of Semi-Log Graph (\(kg/cm^2\)) / Log Cycle for Liquid | - | \(dimensionless\) |
