Role of a project controls engineer in oilfield logistics?

Project Controls Engineer – Oilfield Logistics

Controls cost, schedule, risk, and performance for logistics supporting drilling, completion, production, and abandonment campaigns. Integrates marine, aviation, road, rail, warehousing, customs, and base operations into a single, governed plan and cost baseline.

I. Core responsibilities

I.1 Cost control and earned value – Build logistics control accounts/WBS, set BAC, track AC, compute EV, CPI/SPI, and produce EAC/ETC forecasts by mode (marine/aviation/road/warehousing).
I.2 Schedule development and maintenance – Develop integrated logistics schedules (Primavera/MSP), align with rig plans and 3–6 week lookaheads; drive critical path for rig moves, vessel calls, and flight schedules.
I.3 Change management – Maintain change log and trend register; quantify impacts from scope changes (e.g., extra supply run, weather standby), raise PCRs, and keep baselines current.
I.4 Risk and contingency – Facilitate risk register, model schedule slippage/weather standby with Monte Carlo, set and manage cost/schedule contingency drawdown.
I.5 KPI governance – Define and report OTIF, vessel/truck utilization, demurrage/detention, inventory turns/DSOH, customs clearance time, carbon intensity per tonne-km, and logistics $/unit.
I.6 Data integration and analytics – Reconcile ERP actuals, TMS events, marine/aviation telemetry, and warehouse scans; cleanse data; automate dashboards and S-curves.
I.7 Contractor performance management – Track 3PL/shipowner/aviation SLAs, verify invoices against milestones/GPS, and enforce commercial terms (LDs/bonuses).
I.8 Interface management – Synchronize drilling/completions material call-offs, base operations, customs brokers, and port/airport slots to prevent NPT and congestion.
I.9 Governance and reporting – Issue weekly cost/schedule reports, monthly VOWD, commitment exposure, cash flow, and executive briefings with variance root cause and recovery plans.
I.10 Continuous improvement – Post-ops reviews of rig moves and campaigns; benchmark cycle time, redesign buffers, and standardize playbooks for the next well/campaign.
I.11 Key formulas applied – Use EV methods, utilization, queueing approximations, and emissions calculations for forecasting and optimization.

Metric	Formula	Purpose
Planned Value	PV = \sum \text{Planned cost of scheduled work}	Baseline reference
Earned Value	EV = BAC \times \% \text{ complete}	Value of work performed
Cost Performance Index	CPI = \dfrac{EV}{AC}	Cost efficiency
Schedule Performance Index	SPI = \dfrac{EV}{PV}	Schedule efficiency
Estimate at Completion	EAC = \dfrac{BAC}{CPI} or EAC = AC + ETC	Forecast total cost
Demurrage Cost	\text{Cost} = \text{Hours} \times \text{Rate}	Standby/overage impact
Utilization	\text{Util} = \dfrac{\text{Actual load}}{\text{Capacity}}	Vessel/truck/heli loading
Unit Logistics Cost	\text{$/unit} = \dfrac{\text{Total logistics cost}}{\text{Volume moved}}	Cost benchmarking
Emissions	CO_{2}e = \sum(\text{Activity} \times \text{EF})	Carbon reporting
Little’s Law (est.)	L = \lambda W	Pipeline WIP sizing

II. Required technical skills, soft skills, and physical demands

II.1 Technical skills
- Earned Value Management, WBS/OBS design, cost codes, commitment/VOWD, cash flow.
- Primavera P6/MS Project for integrated logistics schedules and critical path analysis.
- Probabilistic scheduling and cost risk (PERT/Monte Carlo) with confidence curves.
- TMS/WMS/ERP data reconciliation; SQL/Power BI/Python for ETL and dashboards.
- Marine/aviation/road logistics fundamentals: port operations, flight/heli ops, IMDG/IATA, customs/incoterms.
- Invoice verification against contracts, rates, and GPS/telemetry events.
- Inventory math: DSOH, safety stock, reorder points tied to rig consumption profiles.
- Carbon accounting at activity level for scope-related logistics emissions.
II.2 Soft skills
- Stakeholder alignment across drilling, completions, base ops, and 3PLs.
- Variance root-cause analysis and escalation with recovery plans.
- Contract/commercial literacy (SLAs, LDs, gainshare/painshare mechanisms).
- Concise reporting and visualization for executives and operations.
II.3 Physical demands
- Field walkdowns at yards, ports, heliports; prolonged standing and climbing stairs/ladders.
- PPE compliance; exposure to noise, weather, and moving equipment.
- After-hours/on-call support during rig moves or weather disruptions.

III. Typical tools/software/equipment used

III.1 Planning & controls – Primavera P6, MS Project, DCMA checks, risk tools (Monte Carlo).
III.2 Cost systems – ERP/Cost modules (e.g., SAP/Oracle), commitment/VOWD trackers, invoice verification tools.
III.3 Analytics & reporting – Power BI/Tableau, SQL, Python, Excel (Power Query, Solver), S-curve generators.
III.4 Logistics operations – TMS, WMS, yard management, marine AIS, flight/heli scheduling, GPS/telematics, ePOD.
III.5 Mapping & layout – GIS (ArcGIS/QGIS) for route risk; CAD for laydown/yard flow; barcode/RFID scanners.
III.6 HSE & audit – Permit-to-work portals, incident/KPI trackers, audit checklists.

IV. Work environment

IV.1 Location – Onshore logistics or operations center with frequent site visits to pipe yards, ports, bases, and airports; occasional offshore supply base or rig visits.
IV.2 Schedule – Standard weekdays with peaks during rig moves or weather events; rotating duty/on-call during campaigns.
IV.3 Travel – 20–40% typical; higher in multi-basin campaigns or remote operations.
IV.4 Certifications (estimated) – HSE, hazmat awareness (IMDG/IATA), defensive driving; offshore visitor certifications if applicable.
