Oilfield I&E Commissioning Checklist for Wellsites and Batteries
Key Takeaway
An oilfield I&E commissioning checklist covers loop checks, hazardous-area terminations, PLC IO verification, and signed cause-and-effect tests before first production. Producers use it to keep electricians, instrument techs, and PLC programmers on one punch list.
Quick Answer
Oilfield I&E commissioning is the field proof that every transmitter, solenoid, motor starter, and PLC point matches the drawings — and that trips work — before oil moves. A written checklist beats tribal knowledge when night crews and day crews rotate.
Pre-energization
- As-built conduit and cable schedule vs pull cards
- Megger / continuity on power circuits only — isolate or disconnect transmitters before insulation testing instrument loops
- Hazardous-area seals, glands, and labeling intact
- Grounding and bonding for panels and skids
- Nameplates and junction box tags match IO list
See hazardous area Class/Div and instrument loop checks.
Loop and PLC checkout
- Simulate or inject each analog with outputs in a safe state; confirm PLC and SCADA engineering units.
- Stroke every control valve and confirm feedback.
- Prove digital inputs with actual field devices, not only force tables.
- Walk cause-and-effect: HH, ESD, gas detection, fire/eye-wash where installed.
- Capture redlines the same day — do not “remember later.”
Production-ready sign-off
Operations should see a one-page status: open punches (safety vs cosmetic), who owns each item, and whether temporary jumpers remain. Link the checklist to industrial electrical commissioning practices and to pad PLC standards in CompactLogix well-pad programming.
NFM I&E crews run commissioning beside the same engineers who wrote the logic via oil and gas automation — one punch list, one call chain.

Frequently Asked Questions
A loop check proves the signal path from field device to controller (and often SCADA). A functional test proves the process action — valve moves, pump stops, ESD trips — under the real logic sequence.
Typically the I&E lead, controls engineer, and operations or lease representative. Corporate operators often require ISNetworld-compliant paperwork and photo evidence of critical tests.
Local PLC and hardwired trips can be proven first. SCADA tag verification should still close before calling the site ‘remotely operable.’ Do not declare remote-ready if only the local HMI works.
