903 Well Site Completion and Servicing Safety

Setting Production Casing

Production casing is the final casing installed in a well. It can be set from the bottom of the well to the surface, depending on the well design and the type of production needed.

The purpose of production casing is to provide a secure pathway for oil, gas, or other fluids to be brought to the surface safely. It protects the production zone from contamination and prevents fluids from leaking into other underground formations.

Production casing also supports the well structure, holds the pressure from the reservoir, and allows for the safe placement of production tubing and other downhole equipment. Production casing must meet strict industry standards to ensure the long-term integrity of the well.

In some cases, instead of a full casing string, a production liner is used. A production liner covers only part of the wellbore and is usually anchored or tied back to the surface with additional equipment.

This casing is set the same as other casings, and then cemented in place.

Possible Hazards:

• Struck-by hazards from moving casing or equipment during installation.
• Pinch points and hand injuries while aligning or guiding casing sections.
• Slips, trips, and falls on the rig floor due to mud, oil, or tools.
• Exposure to high-pressure fluid release if well control is lost.
• Noise from heavy machinery can lead to hearing damage.

Solutions:

• Use proper lifting tools and follow safe lifting procedures to prevent struck-by incidents.
• Wear gloves and stay clear of pinch points when handling casing.
• Keep the work area clean and dry. Remove unnecessary tools or equipment from walking areas.
• Monitor well pressure continuously. Follow proper well control procedures.
• Use hearing protection in high-noise areas as required by OSHA regulations.
