Colleagues, good afternoon. I apologize, but I want to clarify such a point. Before drilling the well, after RCD installation, the BOP shall be tested together with the casing and RCD. When drilling the casing rigs begins, does the circulation flow through the MPD and Coriolis chokes? If so, there is a high probability of clogging the MPD equipment with rigging elements. Or is there a primary line and an additional line bypassing the MPD equipment? Thank you!
