... automation. Point-the-bit RSS has a different steering mechanism (fixed bend) and it has the sensor offset farther from the bit, which creates challenges for implementation of trajectory automation. In our work, we analysed several case studies and examined new application opportunities for autonomy...

... Abstract Nowadays, complex 3D trajectories are handled with a succession of circular arcs. Although they have constant curvature, their toolface is not constant. Consequently, directional drillers must adjust the toolface regularly to reach the target entry within its tolerances. This paper...

Spatial geometry algorithms are then applied to reconstruct the camera trajectory, which aids in estimating the blade numbers. Finally, each cutter within the segmented blades is further segmented...

... with an RSS, one with the type "Point" and the other with the type "Push Force". These different BHAs are tested in an unconventional well trajectory with or without tortuosity as shown in Fig. 3 . To have representative results, the tests are done in the vertical, curved, and lateral sections...

... Abstract Wellbore trajectories are a fundamental piece of data used for decisions throughout the oilfield. Trajectories are typically mapped through measurement-while-drilling (MWD) survey stations collected at 95ft intervals. Previous work suggests that this sparse sampling interval masks...

... To prevent borehole instabilities, the mud weight and the direction of the wellbore trajectory can be optimized the stability of the hole. The mud weight will determine the hydrostatic pressure in the well that supports the borehole wall in the open-hole section, and this must be designed...

An unexperienced driller could easily produce severe tortuous bends in the well by over-/under-estimating the required tool settings. RSS...

... Abstract Fracture gradient (FG) of wellbores is the function of not only stresses, formation pressure and rock mechanical properties but also well trajectories. An accurate FG prediction is critical for safe well drilling. However, the existing methods do not account for the trajectory effects...
