“Shielding” technology prevents wellbore instability issues ///

The methodologies employed to tackle the profit-draining ramifications of wellbore instability run the gamut, from pumping wellbore strengthening materials (WSM) with drilling fluid, to so-called “stress caging,” whereby fractures are actually created and subsequently sealed with exceptionally precise concentrations of bridging or sealing agents. For the most part, these widely different approaches to maintaining wellbore stability are reactive processes, each of which require additional rig time and costs.
