Splet30. mar. 2024 · Swab and surge is a well-known problem for drilling and well construction operations. Researchers have been investigating this problem since the 19th century. … SpletAbstract. Surge and swab pressures have been for a while an issue in the drilling of an oil well. The drill string causes a flow for displaced fluid and a pressure change in the borehole when running in or pulling out of the hole. When the string moves upward creates a swab pressure and it creates a surge pressures when moves downward.
