-19- FOCUSSED RESISTIVITY SENSOR Abstract of the Invention: A device for detecting and sensing the boundaries between differing rock strata is provided. This device utilizes electrical conductivity or resistivity to detect and measure the boundary layer. The device of the present invention may be used with a "measurement-while-drilling" (MWD) tool, using either wire-line or wireless data communication with a surface receiver. Moreover, the resistivity or conductivity detection device of the present invention may also be used alone or in conjunction with gamma radiation sensors. The present invention utilizes at least a pair of electrodes which occupy a small area and are located on one side of the tool aligned with the longitudinal axis thereof. Thus, in drilling a well along a specific formation stratum (which may be horizontal or inclined), the present invention will act to indicate to the driller whether the drill bit is approaching a stratum boundary, and in which direction that boundary lies. With this information, the driller can take appropriate action to change the direction of the well bore as necessary to achieve the preselected and desired path.
