The basics of mechanical engineering in the oil and gas industry involve the design, construction, and maintenance of equipment and systems used in the extraction, production, processing, transportation, and storage of oil and gas. Key areas of focus include:

• Drilling equipment and systems, including offshore and onshore drilling rigs, blowout preventers, and wellhead systems
• Production equipment, such as production separators, pipelines, and pumps
• Processing equipment, such as refining units, heat exchangers, and boilers
• Storage and transportation equipment, including tanks, pipelines, and loading/unloading systems
• Maintenance and repair, including regular inspections, predictive maintenance, and repair of equipment
