Abstract: An electromagnetic (EM) logging while drilling (LWD) tool is proposed for deep reading detection ahead of the drill bit. The EM LWD tool consists of one coil transmitter sub and two separated coil receiver subs. We utilize the attenuations of measured voltage signals as indicators for detecting the boundary ahead of the drill bit.
