Practical workflow

  1. 1

    Start with mud weight and true vertical depth to establish the hydrostatic pressure baseline.

  2. 2

    Use stabilized shut-in drillpipe pressure for kill mud weight and initial circulating pressure checks.

  3. 3

    Compare the planned circulation schedule against MAASP and casing-shoe pressure limits before relying on any result.

  4. 4

    Use the individual calculators for arithmetic checks, then reconcile outputs with the approved well-control procedure.
