To assure a successful casing deployment into the horizontal section, a flotation collar is often installed to float the casing in horizontal to mitigate the friction and Torque & Drag. However, slim casing may encounter difficulty in circulation and subsequent cementing even after...

... drilling cycle was approximately 66 days for 1000 m of lateral section. The main challenge with motor drilling was high drag at the curve and lateral due to extreme friction as high mud weight was applied to balance the formation stability. This resulted in a poor on- bottom penetration rate during sliding...

.... Some wells can be drilled, but may not be completed due to high friction. Most of today’s torque/drag models are based on the work of Johancsik et. al. (1984) and Sheppard et. al. (1987), while a more comprehensive model is derived by Mitchell and Samuel (2009). If we assume the drill-string...
