Mechanically retrievable packer systems used in oil production in the Suwaydia field (Syria)

The packer system is the most important component of the technological equipment, which is used to carry out work in the reservoir using perforated casing pipes (cased wellbore), as well as in an open wellbore. The types of mechanical packers that are used in the fields of Syria, their technical and operational characteristics, and methods for calculating the main operational characteristics are considered. The work proposes new approaches that allow you to correctly select the required type of packer to perform certain operations inside the well. The problems of effective use of NBR (Nitrile Butadiene Rubber) type packers with nitrile rubber seals in oil and gas fields of Syria have been solved based on a methodology using updated data to calculate the main operational characteristics of packer devices, which will increase productivity and guarantee the operability of equipment used in oil production.
