Abstract
In this article, we discuss the most common pipe sticking problems that occur in general drilling, explore their causes, and practices for solving and preventing them. Although there are various causes of drilling problems, they are mainly related to the drilling fluid, whose characteristics and optimization can help prevent/reduce a number of problems encountered during drilling and save a lot of money. Drilling fluids have undergone major changes since they were first used in the drilling process, leading to more optimal drilling. Its transformation from a simple mixture of water and clay to a more complex combination of various types of organic and inorganic additives has increased the fluid's rheological properties and filtration capabilities. Keywords: pipe sticking, free pipe, differential pressure stuck, drilling fluid, mud cake.
