903 Well Site Completion and Servicing Safety

Starting Production Flow

Several hazards can occur if procedures are not followed or equipment fails. Understanding these hazards and applying the right safety solutions helps prevent accidents, injuries, or environmental damage.

Hazards

• Surging and Swabbing: Surging or swabbing can cause sudden pressure changes that may lead to a kick or blowout.
• Kick: A kick may occur if formation pressure exceeds wellbore pressure, causing fluids like gas or oil to enter the well unexpectedly.
• Wireline Operations: Using wireline equipment without proper control may lead to mechanical failure or pressure-related incidents.
• Setting the Packer: Incorrect setting or failure of the packer can lead to uncontrolled fluid movement or loss of well control.
• Use of High-Pressure Gas: Introducing high-pressure gas to initiate flow can increase the risk of equipment failure or blowout if not monitored carefully.
• Washing In: Flushing out drilling fluid may weaken formation stability, especially if pressure changes are not managed.

Solutions

To reduce these risks, certain safety practices and controls must be followed during the start of production flow. These solutions help maintain pressure control, protect workers, and keep the well stable.

• Well pressure must be monitored closely during all phases of starting production flow.
• Use of blowout preventers (BOPs) must be verified before initiating flow activities.
• Training workers on recognizing and responding to kicks and pressure changes is required.
• Conduct regular maintenance and pressure testing of packers and other downhole equipment.
• Proper procedures must be followed when introducing high-pressure gas or performing unloading operations.
• Ensure communication between surface teams and downhole operations during surging, swabbing, or wireline activities.
