摘要: A method for modifying a return fluid in a wellbore comprises disposing at least one controllable flow restrictor along a drill string in the wellbore. At least one parameter of interest is determined at at least one location along an annulus in the wellbore. Controllably actuating the at least one flow restrictor to modify a local property of a return fluid in the annulus based at least in part on the measured parameter of interest.
