Trajectory optimization

Definition

Trajectory optimization refers to the mathematical and computational techniques used to determine the best path or course for a drilling operation, especially in directional drilling. This involves finding the optimal trajectory that minimizes costs, maximizes efficiency, and achieves desired objectives, such as reaching specific geological formations. The process considers various factors like drill bit performance, geological conditions, and economic constraints to ensure the drilling path is both effective and feasible.
