TITLE: Using Geometrical Parameter Optimization for Automated Path Correction in
3D Geosteering Application

Abstract:
For a drilling engineer, designing and following an optimum well path is of foremost importance to maximize the reservoir contact. But in reality, departure from a planned path is quite common and is usually controlled by Geosteering. Haphazard efforts to bring the well to the designed path create a highly tortuous well path. The tortuosity or smoothness of a wellbore plays a pivotal role in defining the drilling difficulty of the wellbore. In this work 3D, models utilizing smooth curves like Catenary, Clothoid, Bezier and cubic spline were proposed. The models include survey methods like Minimum Curvature, Balanced Tangential Survey, and Natural Curve method. All designed algorithms were bundled together to deliver a streamlined, easy to use software and the application was demonstrated with a simplified prototype. With assistance from the survey, the algorithms can deliver a closed loop system for real time planned path monitoring and path correction.
