Conversely, inside the direction of most horizontal strain, notably at large nicely deviation angles, the Harmless drilling fluid density is better, suggesting a better threat of wellbore instability. Therefore, it can be a good idea to avoid drilling alongside this trajectory whenever doable. As illustrated in Determine 9, once https://vertechs21.wixsite.com/vertechs21/post/innovations-in-mpd-drilling-revolutionizing-well-control
