10. A method for geosteering, the method comprising:
drilling a subterranean wellbore using an integrated drilling system, the integrated drilling system including:
a rotary steerable control unit and an electromagnetic logging while drilling (LWD) control unit deployed in a collar, the rotary steerable control unit deployed below the electromagnetic LWD control unit in the collar, and the rotary steerable control unit configured to control a direction of drilling of the integrated drilling system;
a near bit electromagnetic antenna deployed in a recess in the collar circumferentially about the rotary steerable control unit;
at least one electromagnetic transmitter and at least one electromagnetic receiver deployed in corresponding recesses in the collar circumferentially about the electromagnetic LWD control unit, the at least one transmitter and the at least one receiver configured to make electromagnetic logging measurements while drilling; and
an electrical jumper providing an electrical connection between the near bit electromagnetic antenna and the electromagnetic LWD control unit;
causing the near bit electromagnetic antenna and the at least one electromagnetic transmitter and the at least one electromagnetic receiver to make electromagnetic logging measurements while drilling;
processing the electromagnetic measurements to determine a direction of drilling for the drilling the subterranean wellbore; and
steering the drilling the subterranean wellbore along the direction of drilling.
