ESP Pre-Installation Procedures and Site Requirements

[ALSEngineer]

Technical requirements for ESP installation: wellhead inspection, equipment staging, and environmental limits according to field standards.

Prior to starting the ESP installation, the Rig Supervisor (Driller or Lead Operator) must cross-check the delivered equipment and component serial numbers against the ESP Data Sheets. Verify the physical serial numbers on each unit of the assembly. Additionally, confirm the availability of test reports for all submersible components and the check valve certification. The handover must be documented by signing the appropriate section of the equipment records.

The ESP installation is a joint effort between the ESP Field Technician and the well servicing crew (rig crew), performed under the technical supervision of the ESP Technician. The ESP Field Technician is responsible for the quality of the installation and the integrity of the equipment. Meanwhile, the Rig Supervisor (Toolpusher or Driller) is responsible for the overall site safety and ensuring incident-free operations during the ESP installation and pull.

When the ESP is equipped with a downhole sensor (TMS), the ESP Field Technician monitors the installation and, if necessary, records the relevant data in the Equipment Service Records.

Note: All ESP fastener threads and conditions must be inspected at the service center. You must use only brand-new hardware (bolts, studs, nuts) and O-rings; these are single-use components and shall not be reused. To ensure proper torque control, the use of a torque wrench is mandatory during the entire assembly process.

All external surfaces at the mating faces of the assembly units, as well as the casing head flange, must be cleaned of dust, moisture, and debris, then wiped completely dry.

Remove all foreign objects - such as paper tags, adhesive plastic film, ropes, etc. - from the surfaces of all components being installed. During the assembly process, ensure all shipping dunnage and bracing are removed.

Prior to the ESP installation, arrange all assembly tools and the oil refill tank on the rig floor. To facilitate a smooth installation process, the rig crew must provide a tool table (workstation).

Pay close attention to the condition of the production tubing (OCTG) threads and couplings. All threads must be thoroughly cleaned of storage dope (preservative grease) and inspected for any galling, burrs, or mechanical damage. If any defects are found, these joints must be rejected and set aside. Additionally, verify the availability and condition of centralizers (stabilizers) if they are required by the well program.
