Abstract: A method for deploying a tubular string into a wellbore includes: injecting fluid through a top drive and flow sub into a top of the tubular string and lowering the tubular string into the wellbore. The flow sub: connects the tubular string top to a quill of the top drive, is in a top injection mode, and has a closed port and an open bore. The method further includes halting injection of the fluid through the top drive and lowering of the tubular string. The method further includes, while injection and lowering are halted: disconnecting the flow sub from the tubular string top; adding one or more tubular joints to the tubular string and connecting the flow sub to a top of the added joints. The method further includes resuming injection of the fluid through the top drive and lowering of the tubular string.

Abstract: A method of drilling a subsea wellbore includes drilling the wellbore by injecting drilling fluid through a tubular string extending into the wellbore from an offshore drilling unit (ODU) and rotating a drill bit disposed on a bottom of the tubular string. The method further includes, while drilling the wellbore: mixing lifting fluid with drilling returns at a flow rate proportionate to a flow rate of the drilling fluid, thereby forming a return mixture. The lifting fluid has a density substantially less than a density of the drilling fluid. The return mixture has a density substantially less than the drilling fluid density. The method further includes, while drilling the wellbore: measuring a flow rate of the returns or the return mixture; and comparing the measured flow rate to the drilling fluid flow rate to ensure control of a formation being drilled.
