Whipstock integrated to completion string for coiled tubing operations

A method for sidetracking a well, the method comprising:

• making up a completion string comprising a latching tool removably connected to the completion string, a milling section connected to the latching tool, and a whipstock removably connected to the milling section;
• installing the completion string in the well with the latching tool in a first position, wherein the first position of the latching tool comprises a rotational portion movably disposed around an outer circumferential surface of a stationary portion;
• deploying a coiled tubing having a bottom hole assembly into the completion string to connect the bottom hole assembly to the latching tool;
• placing the latching tool into a second position, wherein the second position of the latching tool comprises the rotational portion immovably disposed around the outer circumferential surface of the stationary portion;
• shearing an anchor shear pin to jut anchor slips from the whipstock to engage with an inner circumferential surface of a wall of the well, a completion shear pin to disconnect the latching tool from the completion string, and a mill shear pin to disconnect the whipstock from the milling section;
• kicking off the milling section from the whipstock into the wall of the well;
• and
• milling through the wall of the well by rotating the milling section using rotational force and weight from the coiled tubing and the bottom hole assembly to sidetrack the well.
