  • Steerable motor system with integrated formation evaluation logging capacity
    Patent number: 5325714
    Abstract: A steerable motor system with integrated formation evaluation logging capacity is presented. The device comprises a housing, a formation resistivity logging tool, a surface signaling device, a density logging tool, a porosity logging tool and a downhole motor and drill. The formation resistivity logging tool is located below the downhole motor and is mounted within the housing wherethrough a drive shaft, extending from the downhole motor, is disposed. Power and signal cables are located within an outer shell of the housing and connect the surface signaling device with the resistivity logging tool. In an alternate embodiment, the resistivity logging tool is located between a motor stabilizer and the drill bit. The present invention allows for increased drill angle during wellbore drilling and formation evaluation.
