ABSTRACT:
A tubing end locator is disclosed having a mandrel and a collet carried by the mandrel. The collet has an annular base and a plurality of fingers having one end attached to the base and a free end extending from the base along the mandrel in parallel, spaced relationship. A beveled lug is carried by the free end of each finger. A flange on the mandrel has a diameter such that the lugs on the fingers will extend beyond the inside diameter of the tubing when the free ends of the fingers are in engagement with the flange. Means hold the fingers in engagement with the flange and resist the re-entry of the fingers into the tubing after the tubing end locator has passed out of the tubing until a substantial upward force has been exerted on the mandrel thereby giving a surface indication that the tool had engaged the lower end of the tubing.
