ABSTRACT:
A system for testing an underground formation penetrated by a well includes a downhole tool that is configured to be coupled to a work string and that includes an outer surface, a connection for coupling a stabilizing sub to the downhole tool, and at least one portion configured to receive a frame. The system further includes a plurality of stabilizing subs that are configured to be coupled to the downhole tool, a plurality of frames configured to be detachably mounted on the at least one portion of the downhole tool, and at least one measuring device configured to be secured in at least one of the plurality of frames. The stabilizing subs each have an outer surface that defines an offset relative to the outer surface of the downhole tool, wherein a first of the plurality of stabilizing subs has a first stabilizing sub offset, and the plurality of frames each have an offset relative to the outer surface of the downhole tool and an aperture for receiving a measuring device, wherein a first of the plurality of frames has a first frame offset determined by the first stabilizing sub offset.
