GRT – RESISTIVITY TOOL
The GRT is an advanced imaging laterolog device incorporating four independent receiving electrodes to create an azimuthally sensitive resistivity measurement. This capability allows the GRT to detect nearby formation beds to determine whether they are conductive or resistive, and to ascertain their direction and distance. Unlike competing tools, it is not necessary to rotate the GRT to obtain directionally sensitive resistivity measurements. Directional resistivity data from the GRT is graphically displayed on a surface monitor (patents pending). The surface monitor is an enhanced version of the familiar ‘compass-rose’ display employed in directional drilling. A continuously updated borehole image showing the distance and direction to conductive/resistive anomalies enables the operator to intelligently direct the drilling process without having to study resistivity logs.
