... of geosteering technology. This algorithm identifies the formation near the drill bit using azimuth LWD data (e.g., gamma), by comparing the upper and lower logging data to control the wellbore trajectory. When the trajectory deviates from the target reservoir, the system automatically control the drill bit...

... angles vary with measured depth. Inclination is the angular deviation from vertical, azimuth is the geographic direction, and measured depth is the along hole arc length referred to a selected datum position at the surface. Targets and wellbore trajectories can also be described by Cartesian coordinates...

.... The limitations of the current wellbore surveying method show the necessity of an improved 3D wellbore trajectory model. The Colorado School of Mines has developed a more robust 3D wellbore trajectory model, the Advanced Spline-Curve (ASC) which allows the industry represent the actual wellpath more precisely...
