On-site Position Overview ADNOC Group is seeking an experienced economic modelling professional to support refinery production optimization, commercial evaluations and economic performance analysis in Abu Dhabi. The role is responsible for developing, maintaining and improving fit-for-purpose economic and Linear Programming (LP) models that reflect actual refinery operating conditions, production constraints and market pricing. These models support feedstock procurement, product and intermediate trading decisions, refinery planning and margin optimization.

Working closely with refinery operations, planning and commercial teams, the position monitors actual performance against planned outcomes, identifies margin improvement opportunities and provides timely economic assessments to support operational and commercial decision‑making.

• Develop and maintain economic models that meet refinery planning, production optimization and commercial evaluation requirements.
• Coordinate within the SCMD team to ensure refinery operating constraints are accurately represented in Linear Programming models.
• Enhance existing LP and economic models to reflect changing business requirements and actual operating conditions.
• Update production constraints, pricing assumptions and relevant business parameters to maintain the accuracy of economic evaluations.
• Develop additional economic models for assessing intermediate products, product purchases and sales opportunities.
• Coordinate with refinery site teams to obtain actual yield patterns, material balances, process constraints and operating information.
• Ensure economic and planning models remain aligned with actual plant performance and current business conditions.

• Conduct economic assessments of crude oil, condensate and other feedstock purchasing opportunities.
• Evaluate proposed sales and purchases of refined products and intermediate materials.
• Prepare economic analyses for additional commercial opportunities and business cases as required.
• Develop supporting calculations, documentation and economic justifications for commercial transactions.
• Prepare presentations and evaluation materials for OC and OSC to support commercial decision‑making.
• Maintain complete and auditable records of economic evaluations, assumptions and decisions.
• Organize and update evaluation databases to ensure relevant information remains accessible for review and reference.

• Support the Senior Specialist, Economic Model, in preparing monthly variance analyses comparing actual refinery performance with approved plans.
• Investigate deviations in production yields, product quality, material balances and operating performance.
• Identify quality giveaway, suboptimal operating conditions and potential margin improvement opportunities.
• Monitor product quality KPIs, process unit yield patterns and component quality variations.
• Recommend measures to reduce deviations between planned and actual refinery performance.
• Track economic losses associated with planned shutdowns, unplanned outages and process limitations.
• Coordinate with refinery site personnel to obtain actual unit yield patterns, hydrogen balances and relevant process data.
• Monitor implementation of refinery operating plans and highlight significant deviations.
• Review unit capacities and operating parameters against economic indicators and recommend revisions when necessary.

• Prepare daily and weekly refinery margin reports and monthly gross margin performance reports.
• Analyse historical and current operating data to identify opportunities for improving refinery profitability.
• Support the management of site Profit Improvement Plan (PIP) programs.
• Maintain and update PIP tracking records and monitor progress against identified improvement opportunities.
• Assess the economic impact of refinery process constraints in consultation with the Senior Specialist, Economic Model.
