WebBorehole stability technology includes chemical as well as mechanical methods to maintain a stable borehole, both during and after drilling. Drilling fluids range from water to oil to complex chemical systems with properties designed for specific site conditions to aid the drilling process. WebInclined borehole stability: Highly inclined boreholes are inherently less stable than those that are near vertical. This has long been recognized in the petroleum sector and is no less a problem in near-surface drilling. Research should focus on the stabilization of inclined boreholes, particularly in the near surface. ...
