Summary: | A formation sampling tool including a plurality of ferrofluidic seals for sealing the formation sampling tool against a wellbore wall of a wellbore, each adjacent pair of the plurality of ferrofluidic seals defining a formation fluid inflow section through which formation fluid enters the formation sampling tool via fluid inflow lines, wherein a first ferrofluidic seal of the plurality of ferrofluidic seals is distal a drill bit, and wherein a last ferrofluidic seal of the plurality of ferrofluidic seals is proximate the drill bit; a formation fluid sampling line, wherein the formation fluid sampling line is in fluid communication with the one or more fluid inflow lines; one or more sensors in fluid communication with the one or more fluid inflow lines and/or the formation fluid sampling line; and a pump configured to pump formation fluid into the formation sampling tool via each of the formation fluid inflow sections. |
