Hole Cleaning In Drilling Deviated & Horizontal Wells
If the well is not circulated well and the hole is not cleaned from cuttings properly, they will gather & settle around the Drill String, usually the Bottom Hole Assembly BHA due to the small clearance between the Bottom Hole Assembly BHA and the hole, which will lead to a stuck probably in the Drill Collar and this stuck will be mainly from inadequate hole cleaning. Here, we shall discuss hole cleaning especially in deviated and horizontal wells.
