Conversely, from the path of utmost horizontal stress, particularly at higher very well deviation angles, the Risk-free drilling fluid density is better, suggesting a bigger danger of wellbore instability. For that reason, it's a good idea to prevent drilling along this trajectory When feasible.The Patchy Aircraft of Weak spot criterion extends Jae

The vertical axis represents tension, plus the horizontal axis represents the gap in the wellbore. The analysis suggests that, compared to the normal faulting and strike-slip faulting pressure mechanisms, You can find a big distinction between σ θTo acquire the wellbore anxiety, it is necessary to establish the conversion connection in between th
