For (1) and (2), the blind rams can be replaced by ,pipe, rams to allow the drill string to be pulled out through the upper rams while the lower rams are kept as back up. For (1), if the drillpipe is in the well and a leak occurs at the mud cross (or the kill line or the choke line), the well can be closed with the ,pipe, rams while the repair job is carried out.

An ,example, method for control of a drilling assembly includes receiving measurement data from at least one sensor coupled to an element of the drilling assembly positioned in a formation. An operating constraint for at least a portion of the drilling assembly may be determined based, at least in part, on a model of the formation and a set of offset data.
