A relatively simple, general, and very flexible method to design complex, three-dimensional
hole trajectories can be obtained by using a 3D extension for Bézier curves. This approach …

Well path design is a primary part of the well plan for well drilling. The main objective of well
path design is to generate a continuous and smooth trajectory from a start point to a target …

The ease of calculation of families of cubic and quadratic Bezier curves using just one or two
control variables makes them well-suited for identifying smooth, deviated wellbore …

The only standard drillstring model in use today is the torque-drag model, and because of
the simplicity and general availability of this model, it has been used extensively for planning …

This paper introduces the practical application of 3D Dubins curve in directional well
trajectory planning to handle more complex downhole conditions such as consecutive …

This work presents the mathematical method to design complex trajectories for three-
dimensional (3D) wells using spline in tension as coordinate functions. 3D spline-in-tension …

The amount of uncertainty related to directional drilling makes it challenging to accurately
model and predict the results of drilling actions, leaving much to human know-how and …

For a drilling engineer, designing and following an optimum well path is of foremost
importance to ensure efficient wellbore placement. But the departure from a planned path is …

The dogleg severity is one of the most important parameters in directional drilling.
Improvement of these indicators actually means choosing the best conditions for the …

Directional drilling is a complex operation that is difficult to execute with precision and
repeatability. It is challenging to accurately model and predict the results of drilling actions …
