I really appreciate you r contribution to knowlegde Sir. Please my question is that in cleaning a highly deviated well (between 45 degrees aand 60 degrees) where we encounter severe avalanche. how do we effective clean the hole? I will appreciate if i can get the formula that supports your answer.
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.
