Whipstock System Open Hole

The system provides a reliable and cost-effective solution for:

• initiating a new lateral borehole from the main wellbore;
• establishing controlled directional drilling trajectories;
• bypassing obstructions or problematic well intervals;
• straightening a deviated or crooked well section;
• improving reservoir access through multi-lateral drilling.

• whipstock with mechanical anchor
• setting tool
• filter pipe
• drill pipe plug

• ensures proper drilling fluid circulation during operations, maintaining wellbore stability and safe tool setting;
• the system can be oriented using MWD or GyroTracker systems for accurate azimuthal positioning;
• provides reliable fixation of the whipstock;
• ensures clear and secure execution of the release and separation from the whipstock after completion of operations.

1. 01Connect the drill string to the setting tool and run in the well whipstock system.
2. 02When running the whipstock system orient the whipstock.
3. 03When whipstock running to the head cement bridge measure the weight move up and down, restore circulation and flush the well AND orient the whipstock (if necessary).
4. 04Stop circulating and unloading activate the anchor assembly and install it.
5. 05Check the installation straining drill string tension 2 tones more than own weight.
6. 06Load for disconnect drill string. Check disconnect to pool the string, but no more than 1-1,5 m to prevent the setting tool from being pulled out of the whipstock.
7. 07Start perating for cementing. After pumping cement, drop the drill pipe plug and pump to whipstock. When the plug is seated in the whipstock, the pressure will increase, indicating that the cement is in the area of the whipstock system.
8. 08The setting tool is lifted from the well.
