... the connection would be fit for the most demanding scenario expected, a comprehensive torque, drag, and fatigue analysis to determine casing installation loads, and a cementing analysis to understand the effect of the new connections outer diameter on cement placement and equivalent circulating density...

... and the wellbore. A torque and drag model was used to obtain the frictional forces between the drillstring and the wellbore. Drillstring dynamics was then simulated using a torsional damped wave equation applying finite difference approximations. Finally, the angular deformation as a function of time and measured...

... torque, flow rate, hydraulic parameters and the three mentioned above. A new technique using lagged features allows data from the well not directly linked to the current operation to act as a proxy for formation properties. This lagging is believed to account for formation changes and bit wear. A fully...
