Understand about Friction Pressure Acting (FrP) in Wellbore

The friction pressure is pressure loss when fluid flowing through flowing paths and it acts in opposite direction of fluid flow. The following factors affect the friction pressure:

• Drilling string geometry both inside diameter and outside diameter

• Fluid Properties: Rheology and density

• Geometry of wellbore: hole length, wellbore area and flow area

• Wellbore condition such as packing off, bridging, etc

• Flow Rate

• Pipe movement and pipe rotation

The figure below demonstrates you how the friction act in wellbore.
