Installing Casing Accessories
As casing is run into the wellbore, various casing accessories are installed to support proper placement, cementing, and long-term well integrity. These accessories may include centralizers, scratchers, guide shoes, and float collars, all of which serve specific functions during casing and cementing operations.
Installing casing accessories often requires close coordination between the drilling crew and specialized service personnel. These tasks involve heavy components, manual handling, and the use of tools in confined work areas, making clear communication and proper sequencing essential for safe operations.
Before casing accessories are installed, the special service supervisor should conduct a pre-job safety meeting with the service crew and all involved rig personnel. This meeting should review individual responsibilities, communication methods, lifting plans, and the sequence of operations to ensure that everyone understands their role and the associated hazards.
Potential Hazards
- Dropping guide shoes, float collars, centralizers, or other casing accessories onto legs or feet during handling.
- Fingers being pinched or crushed between tools, accessories, casing, or tongs while manually positioning components.
- Strains and sprains resulting from lifting, carrying, or positioning heavy casing equipment and tools.
- Exposure to hazardous materials, including thread-lock compounds, lubricants, or other chemical products used during installation.
Possible Solutions
- Use winches, air hoists, cranes, or other powered lifting equipment to handle guide shoes, float collars, and other heavy casing accessories whenever possible.
- Wear appropriate Personal Protective Equipment (PPE) as specified by the applicable Safety Data Sheets (SDS), including gloves, eye protection, and protective clothing.
- Keep hands and fingers clear of pinch points when positioning or tightening casing accessories.
- Use proper lifting techniques and team lifts when manual handling is required.
- Maintain clear communication between the rig crew and service personnel throughout the installation process.
