Whipstock Drilling Mechanisms & Operations In Oilfield
2022-2-10 A whipstock can be set in an open and cased hole. Fig. 1 shows a removable whipstock in an open-hole operation. The whipstock is hard enough to allow milling a window in the casing rather than drilling out the whipstock. There is a myriad of whipstocks available to the industry. Figure 4 is an illustration of a common whipstock.

2006-2-21 The whipstock was set across a length of casing that had cement in the casing by openhole annulus. A number of "Lessons Learned" were obtained during whipstock operations on the A2 ST3 well. These lessons learned and others from previous deepwater whipstock operations were used to help evaluate the risk and optimize the procedures on the A-4 well.
