Snubbing is a process that controls the pressure of oil or gas in order to run or pull tubing, drill pipe, or casing. These applications use the standard snubbing unit to complete or re-complete wells in a “live well” condition. Any type of workover application can be performed utilizing quick jacks.
Snubbing units are often used in place of workover units for offshore applications. Snubbing can offer the same services at a greatly reduced cost to the customer. Snubbing can be performed on live and dean wells. Milling operations can be faster and more precise with snubbing units due to infinite control of torque and speed of the rotary mounted on the snubbing jack. Snubbing is versatile alternative that can overcome the limitations of other workover systems - wireline, coiled tubing and conventional workover rigs. It eliminates the use of kill fluids that can damage the producing formation and require costly disposal. Snubbing is also a faster solution. Snubbing units can often have the task completed before a conventional workover operation is even rigged up.
Snubbing is your best choice when conventional draw works are absent. The self-contained equipment requires little space and can finish the job quickly. The hydraulic system's precise control over force protects against overload and allows responsive tool manipulation.
