One trip whipstock （or single trip whipstock） which can be run into a well, set, and operated from a window in the well casing by a single trip includes a milling tool attached to the upper end of a  hydraulic whipstock to the lower end of which is attached a packer or anchor which can be set by appropriate means prior to detachment of the window casing milling from the hydraulic whipstock to initiate window formation. 

Features
1. Design two rows of anchoring slips to ensure the whipstock set in the casing steadily and stably.
2. Apply 2-3 degrees ramp to make a relatively small dogleg degree at the window and ensure the drilling string pass through the window exit smoothly.
3. Optimal designed milling shoe assembly (including lead mill and dress mill) can achieve high milling speed, low milling torque and smooth window quality.
4. Orient with MWD or UBHO/GYRO available.
5. Only one trip to set whipstock, mill casing exit and drill rat hole.
6. Hydraulic system is retrievable.
