Oil & gas
Part of the Energy & Raw Materials sector
Oil and gas covers the exploration, production, transport, refining and supply of petroleum and natural gas, plus the equipment and services that support them. This hub explains the main segments and how to find and compare verified oil and gas companies on Digibition.

Overview
The oil and gas field is usually described in three segments. Upstream covers exploration and production — drilling, wellheads and field operations. Midstream covers moving and storing product — pipelines, tanks, terminals and transport. Downstream covers refining, petrochemicals and the distribution of fuels and derivatives.
Across these segments sit two broad kinds of supplier. Some sell physical goods: drilling tools, valves, pumps, pipes, instrumentation, drilling fluids and spare parts. Others deliver services: surveying, drilling, inspection, maintenance, engineering and EPC project work. Many companies combine both.
On Digibition, equipment manufacturers, materials suppliers and oilfield service providers publish verified profiles, so buyers, operators and project teams can discover and compare them by specialization and country. This is general information, not legal, technical, or regulatory advice.
What to check when sourcing
Oil and gas is a regulated and safety-critical field, so authorisation and competence matter as much as the quote. For services, check that a provider holds the licences, permits and safety approvals your jurisdiction requires, and ask for references on comparable work. For equipment, confirm the applicable standards and material grades for the pressure, temperature and medium involved.
Many buyers reference industry standards and marks — for example API specifications for oilfield equipment, or recognised pressure and quality-management schemes — as examples of what to verify rather than guarantees. Ask about certificates of conformity, material test reports, traceability and the documentation your market needs.
Because prices here track volatile commodity markets, treat any quote as time-bound and confirm validity, lead time and delivery terms in writing. Use the directory to shortlist companies by segment and country, then contact several and compare their scope, credentials and responses before you commit.

Frequently asked questions
- What does the oil and gas sector include?
- It spans upstream exploration and production, midstream transport and storage, and downstream refining, petrochemicals and fuel distribution. Suppliers range from equipment and materials makers to oilfield service and engineering providers.
- What is the difference between upstream, midstream and downstream?
- Upstream finds and produces oil and gas from the ground. Midstream moves and stores it through pipelines, terminals and transport. Downstream refines it and distributes fuels and petrochemical products to end markets.
- How do I find oil and gas suppliers?
- Use the Digibition directory to filter by this specialization and by country, then open each company profile to review its products, services, certifications and specializations. You can message companies directly, or add several to a quote list and request quotes from all of them at once.
- What should I verify before engaging a service provider?
- Confirm the licences, permits and safety approvals your jurisdiction requires, ask for references on comparable work, and clarify scope, HSE practices and the documentation your market needs. This is general information, not legal, technical, or regulatory advice.
- Why should quotes be treated as time-bound?
- Oil and gas prices track volatile commodity markets, so a quote can change quickly. Confirm the validity period, lead time and delivery terms in writing, and compare several offers before committing.
