Abstract

Summary

Directional wellbore trajectory is a critical aspect of early well planning. Planning the optimum directional wellbore trajectory requires drilling engineers to integrate cross-domain inputs from geologists, geophysicists, and reservoir engineers.

In this paper, we introduce a system to optimize the wellbore trajectory during the planning phase of the well construction. The system will capitalize on early optimization by integrating cross-disciplinary data prior to drilling, allowing for higher spatial correction. The integration will produce a drilling hazard seismic attribute (DHSA) that correlates geologically induced drilling nonproductive time (NPT) from all offset wells per specific field and formation.

Through its cross-disciplinary approach of utilizing historical, geophysical, and drilling engineering, this system drives the full integration and automation process of the well trajectory evaluation. This process is centered on minimizing drilling risks, delivering the optimum well trajectory from the planning stage, and allow engineers to better understand the structural geology and geohazards from the surface to total depth (TD).
