Workover Land Rigs: Onshore Well Maintenance
A workover land rig is a workover rig designed for onshore — or "land" — oil and gas wells. They're the most common type of workover rig in the world, and they're used in every onshore oilfield, from Texas to Saudi Arabia to Russia. Land rigs are built to be mobile, reliable, and cost-effective, because most onshore workover operations are competitive, and you have to keep costs down to make a profit.
Where Workover Land Rigs Are Used
Workover land rigs are used in every onshore oil and gas basin in the world. They service wells in:
- North America: Texas, Oklahoma, North Dakota, Alberta, and more. The US and Canada have the most mature onshore oil and gas industry, and the most workover rigs.
- Middle East: Saudi Arabia, Iraq, UAE, Kuwait, and more. The Middle East has some of the largest oil fields in the world, and they need lots of workover rigs to keep them producing.
- Russia and the Caspian: Russia has a huge onshore oil and gas industry, with lots of workover activity.
- South America: Venezuela, Brazil, Argentina, and more. South America has growing onshore oil and gas production, and demand for workover services is increasing.
- Asia Pacific: China, India, Indonesia, and more. Asia Pacific has growing oil and gas production, and workover rigs are in demand.
What Do Workover Land Rigs Do?
Workover land rigs handle all kinds of well maintenance and repair jobs:
- Pulling and replacing downhole pumps.
- Perforating new zones to increase production.
- Acidizing and fracturing to stimulate the formation.
- Fishing — retrieving broken or stuck equipment from downhole.
- Casing repair and well integrity work.
- Plugging and abandoning wells that are no longer producing.
