A multi-lateral well has a casing, and has lateral wellbores which communicate with the casing through respective windows. A tool at the end of a coiled tubing string is introduced into the well, while disposed in a tool receiving recess of an auxiliary member that is releasably coupled against upward movement relative to the tool. At a selected vertical position within the casing, the auxiliary member is secured against further downward movement, and the releasable coupling is then interrupted to permit the tubing string to move downwardly with respect to the auxiliary member. The auxiliary member may have an inclined surface to deflect the tool into a lateral wellbore. When use of the tool is completed, the tubing string with the tool thereon is moved upwardly, and an arrangement is provided to limit upward movement of the tool relative to the auxiliary member, so that the tool and the auxiliary member are simultaneously withdrawn from the well.
