Abstract
A position-indicating tool includes an outer mandrel that accommodates two or more indicator lugs movable between a first position, where the indicator lugs extend past an outer diameter of the outer mandrel, and a second position, where indicator lugs are radially contracted within the outer diameter, an inner mandrel arranged at least partially within the outer mandrel and providing a radial protrusion that radially supports the indicator lugs in the first position, and a pressure block arranged between the outer and inner mandrels to control a flow of hydraulic fluid between an upper hydraulic chamber and a lower hydraulic chamber, wherein, when a pressure threshold is exceeded in the lower hydraulic chamber, the hydraulic fluid is able to flow into the upper hydraulic chamber and thereby allow the outer mandrel to axially translate with respect to the inner mandrel and move the indicator lugs to the second position.
