From the first day of drilling for oil and gas, increasing efficiency of drilling and lowering the cost is the main goal for well engineering. One of the methods for cutting the expenses is using liner system instead of full casing string. By the time more complex profile (horizontal, ERD), deeper wells drilled. For to answer the industry's these complex requirements liner hanger market also eventually evolved. The evolution is mainly considered as improving liner hangertools capable of withstanding higher temperatures, pressures, and corrosive conditions.

In this article, liner hanger hanger systems, their pros and cons and as well, types are highlighted.
