Claims
- 1. An apparatus for locating a well tool in a cased borehole, comprising:a slip adapted to engage the cased borehole; a cam engaging said slip; a stop member disposed on said slip; a bore extending through said slip and cam; and the apparatus having no sealing engagement with the cased borehole.
- 2. The apparatus of claim 1 further including an orientation member disposed on said slip to angularly orient the well tool in the cased borehole.
- 3. The apparatus of claim 1 wherein said slip has only a sufficient engagement with the cased borehole to allow orientation without rotation of said slip.
- 4. The apparatus of claim 1 wherein said bore has a diameter which is no more than ¾ of an inch less than the diameter of the cased borehole.
- 5. The apparatus of claim 1 wherein the apparatus does not include a seal bore.
- 6. An apparatus to locate a well tool in a cased borehole, comprising:an engaging member adapted to engage the cased borehole; a wedge member engaging said engaging member to force said engaging member against the cased borehole; a locking member engaging said wedge member to maintain said wedge member in engagement with said engaging member; an orientation member disposed on said engaging member; said engaging member, wedge member, locking member, and orientation member forming a bore through the apparatus; and the apparatus providing no sealing engagement with the cased borehole.
- 7. The apparatus of claim 6 wherein the apparatus has no setting mechanism.
- 8. The apparatus of claim 6 wherein the apparatus has no latch.
- 9. The apparatus of claim 6 wherein the cased borehole has a diameter and said bore has a diameter which is no more than one inch less than the diameter of the cased borehole.
- 10. The apparatus of claim 6 wherein said orientation member locates the depth of the well tool in the cased borehole.
- 11. The apparatus of claim 6 wherein said orientation member includes a surface which angularly orients the well tool within the cased borehole.
- 12. An apparatus for locating a well tool in a casing in a borehole, comprising:an insertable member adapted to engage the cased borehole; a stop member disposed on said member; a bore extending through said member; and said bore sized to receive the next consecutive sized casing.
