What does a production operator do in oilfield logistics?

Production Operator (Oilfield Logistics)

Frontline field role focused on safe, efficient movement and custody transfer of produced fluids (crude oil, NGLs, produced water, gas condensate), inventory accuracy, and interface with trucks, pipelines, and terminals.

I. Core responsibilities

I.1 — Execute fluid loading/unloading: spot trucks, connect hoses, verify tank levels, start/stop pumps, monitor pressures, manage vapor recovery, and disconnect per procedure.
I.2 — Perform custody transfer at LACT/ACT units and tank batteries: zero meters, verify meter factors, take temperature/API gravity, water cut, and generate run tickets/BOLs.
I.3 — Conduct tank gauging and inventory reconciliation: manual gauge or ATG verification; reconcile beginning inventory + receipts - shipments - losses = ending inventory.
I.4 — Sample and test quality: S&W, BS&W, API gravity, temperature, basic gas testing at separators/VRUs to meet spec prior to shipment.
I.5 — Manage truck logistics: coordinate with dispatch, sequence trucks to minimize wait time, verify driver documentation, ELD check-in, and direct to safe loading points.
I.6 — Pipeline/terminal interface: line-up valves, pressure/flow checks, witness prover runs, maintain communication with controllers during nominations and batch changes.
I.7 — Equipment operations: start/monitor boosters, transfer pumps, VRUs, heaters, and treaters; adjust chemicals for dehydration/desalting to meet shipment specs.
I.8 — Data capture & reporting: enter volumes, temperatures, densities, truck IDs, run ticket details into SCADA/Logistics TMS; close out daily haul sheets and inventory reports.
I.9 — HSE & compliance: enforce hot-work permits, gas testing, H2S/LEL monitoring, grounding/bonding, spill prevention/response, DOT and hazardous waste rules at the load rack.
I.10 — Routine maintenance/inspection: inspect hoses, gaskets, gound cables, emergency shutdowns (ESDs), overfill protection, meters/strainers; initiate work orders.
I.11 — Loss control and measurement integrity: identify leaks, parasitic losses, or meter drift; assist in on-site proving or schedule metrology support.
I.12 — Abnormal situation management: isolate and depressure lines, manage tank high-level alarms, secure sources during weather or power events, coordinate call-outs.

II.C.3 — Exposure to weather, noise, hydrocarbon vapors, and H2S; extended standing and walking across uneven terrain.
II.C.4 — Use of PPE: FR clothing, H2S monitor, respirator (as required), gloves, face shield, hearing/eye protection.

II.D Key formulas used

II.D.1 — Mass balance: In - Out - Accumulation = 0
II.D.2 — Net standard volume (crude/NGL): \( \text{NSV} = \text{GOV} \times \text{CTL} \times \text{CPL} \times (1 - \text{BS\&W}) \)
II.D.3 — Approx. tank volume (horizontal cylinder, estimated): \( V \approx \pi r^2 h \) (use strapping table for custody transfer; this is for rough checks).
II.D.4 — Truck loading limit: \( \text{Max Load (lb)} = \text{GVWR} - \text{Tare} - \text{Allowances} \); convert to barrels with density at standard conditions.
