The increased impetus on economic efficiency and safety in oil and gas service operations has challenged the industry to seek newer and better strategies that are able to comply with current operational needs. In response to these challenges, state-of-the-art hydraulic workover (HWO) equipment and systems, which can provide alternative methods to traditional drilling and workover operations and can comply with economic and safety constraints, have now been developed. These new systems not only enhance problem-solving options but also increase protection of service personnel and the environment.

This paper will discuss the broader range of applications that has emerged as a result of improvements in HWO technology, the history of these systems, new HWO capabilities, components of the new systems, and safety enhancements recently introduced to the industry. Case histories will provide supporting data.
