It is a critical step in the installation process of an ESP system in a well. The process involves carefully lowering the ESP assembly—typically consisting of the motor, seal section, pump, and cable—into the wellbore to the designated setting depth.
Key Considerations for RIH with ESP:
- Pre-Run Checks:
Inspect all components for damage or defects.
Conduct electrical tests on the motor and cable.
Verify compatibility with well conditions (temperature, pressure, deviation). - Handling and Deployment:
Use a cable spooler to manage the power cable as the ESP is lowered.
Secure the cable to the tubing with bands or clamps to prevent damage.
Ensure smooth and controlled running to avoid sudden shocks or cable damage. - Wellbore Conditions:
Check for obstructions, scale, or debris that could hinder deployment.
Ensure proper well fluid conditions to prevent motor overheating or gas lock issues. - Depth Control & Landing:
Set the ESP at the optimum depth for reservoir production.
Use a tubing hanger or packer, if applicable, to secure the assembly. - Post-Run Verification:
Perform electrical continuity and insulation resistance tests.
Confirm cable integrity and connections before energizing the system.
