What kinds of roles exist in O&G?
The industry is broken into broad functional areas. Most large companies have all of these departments:
Design, build and maintain the infrastructure: rigs, pipelines, refineries, platforms. Covers mechanical, civil, electrical, process and instrumentation engineers.
Ensure operations are safe and environmentally compliant. One of the most in-demand functions; almost every O&G company must have HSE officers by law.
Run the day-to-day: production, logistics, field supervision, vessel operations. Hands-on roles that keep oil and gas actually moving.
Plan and deliver large capital projects: new platforms, pipelines, refineries. Strong demand for PMs with O&G or heavy industry experience.
Budgeting, cost control, contracts negotiation, procurement. Finance teams in O&G companies are large and need qualified accountants and analysts.
Data analytics, SCADA systems, cybersecurity, SAP/ERP management. The industry is digitising fast and there's a shortage of tech talent who understand O&G.
JV agreements, regulatory compliance, tendering, NNPC contracts. Lawyers and contracts professionals are in high demand across operators and service companies.
Source and manage vendors, manage logistics, ensure equipment reaches site on time. A critical function with roles at all seniority levels.
Keep equipment and facilities running safely and efficiently. Covers mechanical, electrical and instrumentation technicians through to maintenance supervisors and reliability engineers.
Analyse fluid samples, monitor production chemistry and ensure product quality. Biochemists, chemists and microbiologists have a clear home here across refineries, processing plants and offshore platforms.

How to actually break in
-
1Target service companies first. It's often easier to get into O&G through service companies (Schlumberger, Baker Hughes, Halliburton, Oilserv, Amaiden) than going straight to operators like Shell or TotalEnergies. Service companies hire more regularly and are less selective about prior O&G experience.
-
2Get the right certifications. For HSE: NEBOSH IGC or ISPON membership opens doors fast. For Engineering: COREN registration is almost mandatory. For Finance: ICAN or ACCA. These signal seriousness to O&G hiring managers.
-
3Use industry language on your CV. Don't just say "managed projects". Say "delivered CAPEX projects within budget." Learn the acronyms: OPEX, CAPEX, FPSO, SIMOPS, HSE MS. Hiring managers notice.
-
4Get work experience as fast as possible, even if it means volunteering. A degree with zero O&G exposure is a hard sell. If you can't land a paid role immediately, offer to support an HSE audit, assist at a service company, or shadow a professional in your discipline. Practical exposure on your CV changes everything and shows you're serious about the switch.
-
5Join SPE (Society of Petroleum Engineers). SPE Nigeria has a strong student and young professional chapter. Membership gives you access to industry events, technical papers, mentorship programmes and a direct network of people already working in O&G. It's one of the fastest ways to close the gap between where you are now and the information, people and opportunities you need to succeed. Join at spe.org.
-
6Look for Graduate Trainee programmes. Shell, TotalEnergies, Seplat, Oando and Dangote all run structured graduate programmes that don't require prior O&G experience. These are some of the best entry points into the industry.
-
7Don't ignore smaller operators. Mid-sized Nigerian independents (Eroton, Neconde, First E&P, Waltersmith) hire constantly and offer faster career progression than the majors.
Be aware of opportunities and be ready for them when they come. The O&G job market moves fast. Roles open and close within days, and the people who land them are usually just the ones who saw them first. Being aware of what's out there and being ready when the right role comes up is half the battle.
