HYDRAULIC WORKOVER / SNUBBING EQUIPMENT
International Snubbing Services performs services in virtually any environment and anywhere globally due to the resourcefulness of our in house manufactured equipment designs. Always leaving a minimal footprint for both offshore and onshore operations, ISS is able to build solutions for our customers with our Hydraulic Workover Units' innovative technology. As a leader in the Snubbing industry, our team is consistently striving to perform at the highest productivity levels possible, leading always with safety at the core of every task.
Snubbing units have been around since the 1920's as a result of the oil and gas industry needing a better system in place to kill the well. The modernized cost effective snubbing units developed by ISS use a sophisticated hydraulic system to power the components of the operation. When your company needs well control equipment, call the best at ISS!

How Does It Work?
Hydraulic Workover is a well intervention technique which can be used to install or remove tubular pipes in or out of dead wells. The term “dead well" means that the well has zero surface pressure and has a heavy fluid or mud in the wellbore, or is not capable of sustaining natural flow. The pipes are pulled out of the well using hydraulic cylinders.
Hydraulic Power
The HWO unit (Hydraulic Workover Unit) utilizes hydraulic cylinders to lift the tubular in or out of the well. The use of hydraulic cylinders allows perfect control over tubular movements and eliminates the use of a large mast construction which is present on conventional drilling rigs.
Hydraulic cylinders can generate large pull and push forces and give the HWO unit a small footprint and layout. These properties are especially beneficial for offshore operations where space is limited and where weather conditions can be harsh.
