Oil plays a central role in the nation's economy. Without access to crude oil, it would be impossible to create and transport the consumer goods the public relies on.
Drilling companies use wells to extract oil from deep below the Earth's surface. It is inevitable that a well will experience some performance problems at some point during its lifetime. When a well stops performing as it should, a workover rig is called to the scene.
What is a Workover Rig?
The easiest way to explain the role of workover rigs in the oil well industry is to liken these pieces of equipment to a car mechanic. Regardless of what is causing a well to experience production issues, a workover rig is called in to address these performance problems and make the well productive once again.
Since a workover rig performs both diagnostic and repair functions, these rigs are complex pieces of equipment.
What Causes a Well to Stop Working?
To truly understand the integral role workover rigs play in the oil well industry, you need to be able to determine the types of problems these rigs can address.
Well performance is affected by a variety of factors. Changes in the oil reservoir the well has tapped in to and deteriorating equipment are among the top aggravating factors that negatively affect oil wells.
A workover rig can replace large tubing to accommodate a slower oil reservoir and pull up any deteriorating equipment to make repairs. These vital functions help oil companies avoid financial losses by ensuring all wells continue to produce oil for as long as possible.
How do Workover Rigs Work?
A workover rig is a standalone piece of equipment that relies on three primary techniques to make repairs: wireline, coiled tubing, and snubbing.
During a wireline, measurement devices are lowered into the oil well to determine the extent of the damage. Coiled tubing can also accommodate measurement devices, but its primary purpose is to deliver chemicals to the well.
Snubbing is a last resort when other techniques have failed. The snubbing process requires that a bottom hole assembly be run via a specialized hydraulic workover rig.
Well intervention is necessary to ensure that each oil well that has been drilled continues to meet production goals. Workover rigs are essential to the diagnosis and repair of wells that have started to malfunction. Invest in a workover rig to service your wells in the future.
