Workover and Abandonment Operations Safety
Workover
Workover activities include one or more types of remedial operations performed on a producing oil or gas well. The main goal is to increase or restore production. These operations are often performed using a workover rig. A typical workover crew includes four or more trained workers. The rig is used to complete, stimulate, repair, and maintain an existing well. Because this work involves high-risk equipment and flammable materials, strong safety practices are critical at all times.
Workover activities try to increase production.
Potential Hazards
- Guy wires: Trip hazards or structural failure if not properly marked or maintained.
- Live gas production lines (high pressure): Risk of explosion, fire, or exposure to toxic gases.
- Liquid fuels and hydraulic fluids: Flammable materials that can ignite if spilled or exposed to sparks or heat.
- Existing producing gas wells: Blowout or pressure release risk during workover operations.
- Tanks and pits with flammable liquids or chemicals: Potential for inhalation of vapors, burns, or environmental contamination.
- Single egress/ingress access road: Limited escape and emergency response access in case of an incident.
