Thank you Sir and God bless

The good drilling practices will help you. You should do the following actions to get the good hole cleaning in highly deviated wells.

1 Mud properties mud be good for cutting carrying.

2 Flow rate must be more than cutting slip velocity. Sweep should be pump periodically to clean the cutting sat at the low side.

3 Circulate and reciprocate pipe as fast as possible without harming your wells.

4 Ensure the shale shakers are clean to confirm the hole cleaning

5 Pump out of hole at the highly deviated area and circulate bottom up above that point to clean the dragged cutting.
