Well Control - Deviated and Horizontal wells
All hydrostatic pressure-related calculations should be based on true vertical depth values. This means that the standpipe kill graph of a deviated well has a different curve as compared to the graph prepared for a vertical well due to the behaviour of Pdp. It applies only for phase I (balanced method), since the standpipe pressure remains constant for the other phases.
1. Kick control in deviated wells
When the standpipe kill graph for a deviated well is constructed according to the procedure outlined in Section 126.96.36.199 (vertical . . .
