Structural steering is a method of directing the wellbore trajectory of horizontal wells using 3D visualization. It is the process of combining structural analysis and modeling capabilities with borehole images to optimize well placement, often in real-time. Structural steering integrates deep-reading LWD resistivity tools and high-resolution imaging devices to create structural models of often complex geologic conditions encountered by the drill bit. This technique helps operators understand the formations already drilled and allows them proactively to correct wellbore trajectories for anticipated changes.
