It is a critical operation for isolating zones, conducting well interventions, or preparing for abandonment. Here’s a step-by-step guide on how to run a bridge plug properly:
- Pre-Job Planning
Select the Right Bridge Plug: Choose a plug suitable for well conditions (pressure, temperature, casing size, and wellbore fluids).
Check Well Parameters: Ensure wellbore is clean and free from obstructions.
Prepare Tools & Equipment: Use an appropriate setting tool (mechanical, hydraulic, or wireline-set), running string, and safety equipment. - Rig Up and Run in Hole (RIH)
Rig Up Equipment: Assemble the bridge plug with the setting tool on a work string, wireline, or coiled tubing.
Lower the Plug to Depth: Slowly run the assembly downhole while monitoring depth using well logs, tag indicators, or depth counters. - Setting the Bridge Plug
Activate the Setting Mechanism: Depending on the type of bridge plug:
Wireline-set: Use an electric line setting tool to activate the plug’s slips and packing elements.
Tubing/Drill Pipe-set: Apply mechanical or hydraulic force to expand the slips and set the plug.
Coiled Tubing-set: Use hydraulic pressure to set the plug in place.
Confirm Setting: Verify with weight changes, pressure tests, or well logging tools. - Pressure Test & Verify
Pressure Up the Plug: Apply pressure above the plug to confirm isolation.
Monitor for Leaks: Check pressure stability for a certain time to ensure proper sealing. - Retrieve or Leave in Place
If it’s a retrievable bridge plug, use the appropriate retrieval tool to unset and pull it out.
If it’s a permanent bridge plug, leave it in place and proceed with further operations (e.g., cementing, well abandonment).
