Slow Circulating Rates (SCRs) refer to the use of slow pump rates during circulation to manage wellbore pressure, especially during situations where there is a need to control or “kill” the well. SCRs are integral in maintaining stability and safety in drilling environments, as they help manage bottom hole pressure, mitigate friction in the annulus, and provide additional control over circulation pressures. Let’s delve deeper into why SCRs are essential, how they are applied, and the importance of accounting for friction pressures, particularly in subsea operations.
