Modeling of Pipe Friction and Smear Effect in Drilling Operations
… on two such issues: 1) to model the influence of wellbore friction on downhole temperatures of the drilling fluid, 2) to understand the smear effect mechanism observed in a casing while drilling operation through mathematical studies. An analytical model has been proposed to estimate the increase …

Downhole Weight on Bit Prediction with Analytical Model and Finite Element Method
… surface panel is most often incorrect because wellbore friction along the drillstring is not considered. Drillstring force modeling computer simulation can be utilized to economically determine the actual WOB value. In this thesis, two drillstring force models are programmed and compared: an …

A Calculation Model for Steam Property Variation Along Wellbore Trajectory in SAGD Process
… decreases during the steam flow inside vertical wellbore because the steam loses its heat through wellbore system to formation due to temperature gradient. And in horizontal wellbore, steam even flow into formation through slotted liner which takes away energy directly. For a SAGD project, the …
