Technical Skills for Oil & Gas Jobs in the GCC: Complete Skills Matrix

Oil & Gas Technical Skills in the GCC

The GCC produces over 20 million barrels of oil per day and holds approximately 30% of global proven crude oil reserves, cementing its position as the world’s most significant hydrocarbon-producing region. Saudi Aramco, ADNOC, Qatar Energy, Kuwait Petroleum Corporation (KPC), and PDO Oman operate some of the world’s most complex upstream, midstream, and downstream facilities, from the Ghawar supergiant field in Saudi Arabia to the North Field in Qatar and the ADNOC offshore concessions. The energy transition is adding hydrogen, CCUS (carbon capture, utilisation, and storage), and renewable energy integration skills to traditional petroleum engineering competencies, creating a dual demand for both conventional and future energy technical expertise.

Employment in GCC oil and gas spans national oil companies (NOCs), international oil companies (IOCs), oilfield service providers (SLB, Halliburton, Baker Hughes), engineering procurement construction (EPC) firms (Technip Energies, Worley, Saipem), and a growing ecosystem of technology companies serving the sector. The technical skills required vary significantly across these organisations, but there is a common foundation of software, safety, and regulatory knowledge that all professionals in the sector must possess.

Reservoir & Production Engineering

Reservoir and production engineering sits at the heart of the GCC oil and gas industry, responsible for maximising hydrocarbon recovery from the region’s vast reserves. Technical skills in this area combine software proficiency, subsurface understanding, and data-driven decision making.

• Eclipse / Petrel / CMG — Reservoir simulation and geological modelling software that forms the daily toolkit of GCC reservoir engineers. Eclipse 100 for black oil simulation and Eclipse 300 for compositional simulation handle the complex fluid behaviours found in GCC carbonate reservoirs. Petrel provides the integrated subsurface workflow environment connecting seismic interpretation, geological modelling, and simulation. CMG (GEM, IMEX, STARS) is also used, particularly for thermal recovery studies and unconventional reservoir modelling. Skills in history matching, uncertainty quantification, and field development planning using these tools are essential for reservoir engineering roles at Aramco, ADNOC, and their appointed consultancies.
• PROSPER / GAP / MBAL — The IPM suite by Petroleum Experts is used daily by production engineers across GCC fields for well performance optimisation, production network modelling, and material balance analysis. PROSPER models individual well performance and artificial lift design, GAP optimises field-wide production network allocation, and MBAL provides reservoir pressure and reserves estimation. Proficiency in building integrated models connecting wellbore, surface network, and reservoir is expected for mid-level and senior production engineering roles.
• Nodal Analysis & Artificial Lift — Gas lift, electrical submersible pump (ESP), and rod pump design optimisation are critical for mature GCC fields seeking to maximise recovery. Saudi Aramco operates one of the world’s largest gas lift systems, while ADNOC relies heavily on ESPs in its offshore fields. Understanding artificial lift selection criteria, pump curve analysis, and gas lift optimisation using WellFlo or PROSPER is a key differentiator for production engineering candidates.
• Production Data Analytics — Python and MATLAB for decline curve analysis, well test interpretation, and production forecasting are increasingly expected alongside traditional petroleum engineering tools. Aramco’s EXPEC ARC and ADNOC’s AI and data analytics division actively recruit engineers who combine subsurface domain knowledge with data science skills.

Process & Plant Engineering

Process and plant engineering roles serve the GCC’s massive refining, gas processing, and petrochemical operations. ADNOC Refining, SABIC, Qatar Energy’s LNG trains, and Kuwait’s Al-Zour refinery represent some of the world’s largest processing complexes.

• HYSYS / Aspen Plus — Process simulation for refining, gas processing, LNG liquefaction, and petrochemical operations. Aspen HYSYS is the standard tool for steady-state and dynamic simulation across GCC process engineering teams. Aspen Plus handles complex chemical processing simulations for petrochemical plants. Skills in heat exchanger network optimisation, distillation column design, and process energy efficiency using these tools are required at companies like ADNOC Refining, SABIC, and Qatar Energy.
• SmartPlant / AVEVA — 3D plant design and piping layout for brownfield modifications and greenfield developments. AVEVA E3D is increasingly replacing Intergraph SmartPlant 3D across GCC EPC projects. Skills in piping stress analysis (using CAESAR II), instrumentation design (using SmartPlant Instrumentation), and intelligent P&ID management are valued for design engineering roles.
• HAZOP / SIL Assessment — Safety integrity level (SIL) studies, hazard and operability analysis (HAZOP), and LOPA (layer of protection analysis) are mandatory for process safety roles in GCC petrochemical and refining operations. Understanding IEC 61508 and IEC 61511 functional safety standards alongside GCC-specific safety regulations is essential. PHAWorks and PHA-Pro are common HAZOP facilitation tools.

Drilling & Well Engineering

The GCC drills thousands of wells annually across onshore and offshore environments, from Saudi Arabia’s vast onshore fields to ADNOC’s complex offshore developments and Qatar Energy’s North Field expansion wells.

• Drilling Engineering Software — Landmark/Halliburton tools (COMPASS for directional drilling planning, StressCheck for casing design, OptiCem for cementing) form the primary software suite. WellPlan for torque and drag analysis, hydraulics modelling, and swab/surge calculations is standard. Schlumberger’s Techlog for petrophysical analysis and wellbore stability modelling adds value for well engineering roles. Understanding managed pressure drilling (MPD) technology and slim-hole drilling techniques is increasingly valued as GCC operators push into more challenging reservoirs.
• Well Control Certification — IWCF (International Well Control Forum) or IADC WellCAP certification at the appropriate level is mandatory for all drilling operations personnel in the GCC. Level 2 is required for drillers and assistant drillers, Level 3 for toolpushers and drilling supervisors, and Level 4 for company representatives and rig managers. This certification is non-negotiable across all GCC operators and must be maintained with periodic revalidation.

HSE & Compliance

Health, safety, and environmental compliance in GCC oil and gas is among the most stringent in any global market, reflecting both the inherent hazards of hydrocarbon operations and the regulatory priorities of national authorities.

• Process Safety Management — OSHA PSM (29 CFR 1910.119), API RP 75 (recommended practice for development of a safety and environmental management program), and ADNOC COPV (Codes of Practice) standards. Loss prevention, barrier management, and bowtie analysis using BowTieXP or CGE Risk Management Solutions are key competencies. Understanding Management of Change (MOC) procedures, process hazard analysis methodologies, and safety-critical element management differentiates process safety professionals.
• Environmental Compliance — Flaring reduction programmes, continuous emissions monitoring systems (CEMS), and environmental impact assessment (EIA) procedures. GCC countries are tightening environmental regulations under Paris Agreement commitments and their own net-zero targets (UAE 2050, Saudi Arabia 2060). Skills in greenhouse gas emissions quantification, methane leak detection and repair (LDAR), and environmental permitting are growing in demand.
• NEBOSH Oil & Gas Certificate — The NEBOSH International Technical Certificate in Oil and Gas Operational Safety is the industry-standard safety qualification for O&G professionals in the GCC. It covers process safety, fire and explosion hazards, and hydrocarbon-specific risks. NEBOSH Diploma and Certified Safety Professional (CSP) certifications are expected for senior HSE management positions.

Energy Transition Skills

The energy transition is not a distant future scenario in the GCC—it is happening now. Every major NOC has committed to significant decarbonisation investments, creating substantial new demand for transition-ready technical skills.

• Hydrogen Production — Blue hydrogen (steam methane reforming with CCUS) and green hydrogen (water electrolysis powered by renewables) process knowledge. The NEOM Green Hydrogen project, a joint venture between ACWA Power, Air Products, and NEOM, will be one of the world’s largest green hydrogen facilities. ADNOC has committed to producing 1 million tonnes per annum of blue hydrogen. Skills in electrolyser technology (PEM, alkaline, SOEC), hydrogen compression and storage, and ammonia synthesis for hydrogen transport are in growing demand.
• Carbon Capture (CCUS) — CO2 capture, compression, transport, and geological storage technology. Al Reyadah, ADNOC’s operational CCUS facility, captures 800,000 tonnes of CO2 annually. Saudi Aramco’s Jubail CCS project and Qatar Energy’s Ras Laffan CCUS facility represent expanding operational capacity. Process engineers with skills in amine-based CO2 capture, membrane separation, and subsurface CO2 storage modelling (using CMG GEM or Eclipse) are being actively recruited.
• Sustainable Aviation Fuel & Renewables Integration — GCC NOCs are investing in sustainable aviation fuel (SAF) production, solar PV integration at upstream facilities, and wind power for remote operations. ADNOC has committed to 100% clean power for its grid operations. Understanding how to integrate renewable energy into traditional O&G operations infrastructure is a valuable emerging skill.

GCC Context

Saudi Aramco’s multi-trillion dollar valuation, ADNOC’s USD 150B+ growth strategy that spans conventional oil, gas, chemicals, and new energy, and Qatar Energy’s North Field Expansion (the world’s largest LNG project, adding 6 new mega-trains) drive sustained demand for technical talent. KPC’s Clean Fuel Project and PDO Oman’s enhanced oil recovery programmes add further opportunities. Understanding the HSE culture specific to NOCs, which often exceeds international standards, and familiarity with local regulations (ADNOC HSE Standards, Saudi Aramco Engineering Standards, Qatar Energy HSEMS) differentiates successful candidates from those with only international experience.
