Abstract
A scoop capable of orienting a orientable downhole tool, such as a whipstock assembly, comprising: an orienting member that includes a helical upper surface that terminates in a first pin engaging slot. The pin engaging slot includes upper and lower closed ends such that when the orientable downhole tool advances toward the orienting member, a pin on the orientable downhole tool engages the helical upper surface and orients the orientable downhole tool assembly and when said pin on the orientable downhole tool assembly engages the slot, the orienting member resists axial movement in either axial direction and resists rotational movement in either rotational direction. An alternative embodiment comprises: an orienting key member that includes a helical upper surface that terminates in a first pin engaging slot, and a supplemental member including at least one guide surface terminating in a second pin engaging slot, wherein the orienting member and the supplemental member are concentrically engaged and axially positioned relative to each other such that when the orientable tool advances axially toward the scoop, an orienting pin on the orientable tool engages the helical upper surface and azimuthally orients the orientable tool before a supplemental pin on the orientable tool engages said supplemental member.
