A workover rig is a specialized piece of equipment used in the oil and gas industry to perform maintenance or repairs on existing wells. It can remove and replace equipment, such as pumps and tubing, to enhance production or address issues like blockages. Workover rigs are essential for extending the life of a well and ensuring its efficiency. These rigs are typically mobile and can be transported to various locations as needed. They come in different sizes and configurations, depending on the specific requirements of the well. The operation of a workover rig is crucial for maintaining the productivity of oil and gas fields, contributing to the overall energy supply.
