Figure 32-2. Generalized diagram of steps involved in deflection of a well by means of a 

 whipstock. (1) Whipstock in place prior to shearing of pins holding bit to whipstock. 

 (2) Drilling of first portion of deflected hole. (3) Pulling out of hole to remove 

 whipstock — bit will not pass through the upper collar of the whipstock; hence whip- 

 stock is removed with the drill string (Modified after Murdoch).
