ABSTRACT:
A well tool and method are provided for evaluating a subterranean formation through an exposed formation surface, such as the wall of a newly drilled well bore. The tool has a tubular main housing that is connectable into a well work string. A probe and a scraper are extendible from the main housing in response to a first signal of a signal set transmitted from the surface. The probe and the scraper are returnable to the main housing in response to a second signal set transmitted from the surface. The probe provides an isolated fluid conduit from the formation surface to a sensor for measuring a condition in the well. The scraper is for removing debris and for smoothing the formation surface, thereby helping to establish a sealed engagement of the probe to the formation surface. The tool can also be provided with a sampling vessel for taking samples of formation fluids obtained via the isolated fluid conduit in the probe.
