Description
Kai Wei and co-authors build in 2026 a quantitative method for predicting when a logging cable will stick inside an oil or gas well. Such accidents halt operations and risk losing expensive instruments downhole. Their approach rests on a soft string model of the cable's mechanics. The model derives the adhesion forces that build as the tool is jacked through the borehole and converts them into a sticking risk probability. A real well served as the test case for validation.
The assessed well showed signs of sticking, matching what crews actually observed in the field in the reported comparison. Sensitivity analysis found risk most responsive to borehole inclination and drilling fluid density among the factors tested. Managing the main sensitive factors together cut overall sticking risk by roughly a third in their calculations. Engineers planning wells gain a pre-run risk check rather than learning about adhesion the hard way.
