Аннотация


This paper presents new method to prevent stuck pipe or at least to decrease its probability while drilling of oil and gas wells. This method which is applicable in both vertical and deviated wells incorporates using nanoparticles in drilling mud composition to decrease mud cake thickness. So by having less mud cake thickness, probability of stuck pipe decreases. Also different mechanisms of stuck pipe in Ahwaz and Abb-Taymoor oil fields are considered and new approach is suggested to use, while drilling of most sensitive formations respect to stuck pipe in these oil fields.
