Abstract
An illustrative electromagnetic logging while drilling system includes a drill string having a bottomhole assembly with a bit that operates to extend a borehole; and further includes a removable add-on antenna unit that cooperates with at least one other antenna unit in the drill string to provide electromagnetic signal measurements indicative of at least one formation property. Some embodiments of the add-on antenna unit encircle an existing tool or tubular, attaching to a sidewall readout port to receive power and exchange communications over the internal tool bus with at least one other antenna unit. At least one disclosed method embodiment includes: assembling the bottomhole assembly; securing at least one add-on antenna unit around a downhole tool or tubular in the bottomhole assembly; and using the at least one add-on antenna unit in combination with at least one other antenna in the bottomhole assembly to obtain electromagnetic signal measurements formation properties.
