Abstract: A multilateral entry tool enables an operator to identify a target lateral wellbore, and efficiently guide a bottom hole assembly (BHA) into the target lateral for diagnostic, servicing or other wellbore operations. The multilateral entry tool provides independent control over both kick-over and orientation mechanisms such that the operator may either pivot the BHA without rotating, or rotate the BHA without pivoting. The BHA may be rotated in either direction, and the degree that the BHA can be pivoted may be fully adjustable. Sensors on the entry tool may penult the operator to verify a successful lateral entry, and the BHA may be straightened to reduce drag as the BHA is advanced into the lateral wellbore.

Abstract: A housing of a dual rubber cartridge attaches at least one rubber to an inner barrel for rotation with the inner barrel.

The user may then replace the original housing with a second housing on which new rubbers are installed. The housing enables the user to quickly replace the rubbers to reduce down time of the drilling operation.
