Rotary steerable, directional-drilling systems increased rate of penetration (ROP) and saved more than 100 days of rig time when used to drill complex 3D wellpaths in the 121/4-in. and 81/2-in. hole ...

At-a-Glance: Directional drilling has rapidly advanced via autonomous rotary steerable systems, high-speed telemetry, deep-looking LWD, and AI-driven trajectory control—delivering faster, smoother, ...

Efficient drilling in shale reservoirs requires detailed 3-dimensional (3D) horizontal well trajectories. An orthogonal-arc trajectory (OAT) method assumes a single constant curvature in the curved ...

Directional drilling on multi-well pads is used to drill multiple wells from a single surface location to different subsurface targets, optimizing surface footprint, cycle time, and cost while safely ...
