The Educational Foundation: Cal Poly Pomona's "Learn by Doing" Philosophy
For an aspiring engineer like Monica Marquez, the choice of university is pivotal. Cal Poly Pomona’s College of Engineering is renowned for its "learn by doing" philosophy. This is not merely a slogan but the core methodology that differentiates its graduates. In the context of oil and gas, this means that theoretical knowledge from courses in fluid mechanics, thermodynamics, materials science, and process dynamics is directly applied in laboratories, design projects, and often through required cooperative education (co-op) or internship experiences.
A student following this path would typically major in Chemical Engineering, Mechanical Engineering, Civil Engineering (with a geotechnical focus), or Electrical Engineering. Each discipline feeds into different segments of the industry. Chemical engineers are crucial for refinery operations, process design, and petrochemicals. Mechanical engineers work on drilling equipment, pipeline systems, and compression machinery. Civil engineers contribute to offshore platform structures and pipeline routing, while electrical engineers handle instrumentation, control systems, and power distribution on remote sites.
The key for the student is to leverage the university’s resources early. This involves seeking out professors with industry experience, joining relevant student chapters such as the Society of Petroleum Engineers (SPE) or the American Institute of Chemical Engineers (AIChE), and participating in design competitions that often have energy-related themes. The goal is to build a portfolio of practical project experience before even applying for a first job. This hands-on competency is what employers immediately recognize in graduates from programs like Cal Poly Pomona’s.
Core Engineering Disciplines and Their Oil & Gas Roles
Understanding where your specific engineering skills fit within the vast oil and gas supply chain is essential for targeting your job search and professional development.
Chemical Engineers are process specialists. Their domain spans from the upstream sector, where they might work on reservoir fluid properties and surface facility design to separate oil, gas, and water, to the midstream and downstream sectors. In midstream, they design and optimize gas processing plants that remove impurities. In downstream, their primary arena is the refinery. Here, they are responsible for the complex processes of distillation, catalytic cracking, reforming, and treatment that transform crude oil into gasoline, diesel, jet fuel, and feedstocks for plastics. Their work ensures efficiency, yield, and safety in some of the most intricate industrial facilities in the world.
Mechanical Engineers are the equipment experts. In drilling operations, they specify and maintain the massive machinery on rigs. They are responsible for the integrity of pressure vessels, heat exchangers, and turbines. A significant portion of their work involves pipeline engineering—designing systems for the safe and efficient transport of hydrocarbons over hundreds or thousands of miles. This includes calculating wall thickness, selecting materials to prevent corrosion, and designing pumping/compressor stations. Their skills in thermodynamics and fluid mechanics are constantly applied to solve practical problems of flow, pressure, and heat transfer.
Civil and Environmental Engineers focus on infrastructure and sustainability. Civil engineers design the foundations for offshore platforms, ensuring they can withstand hurricane-force winds and waves. They plan the route for pipelines, considering soil mechanics, seismic activity, and environmental crossing. Environmental engineers, increasingly vital, work on mitigating the industry’s impact. They develop systems for water management (both produced water and frac water), emissions control, and site remediation. Their role ensures regulatory compliance and helps implement the industry's evolving environmental, social, and governance (ESG) mandates.
Electrical and Computer Engineers/Computer Scientists drive digitalization. They design the power systems that run remote facilities, often involving complex off-grid solutions. Their deeper impact is in automation, control systems, and data analytics. They program and maintain the Supervisory Control and Data Acquisition (SCADA) systems that monitor and control pipelines and plants. Today, they are at the forefront of deploying Internet of Things (IoT) sensors, using data science for predictive maintenance, and developing software for reservoir simulation and seismic data interpretation. This discipline is central to the industry’s shift towards "smart fields" and operational efficiency.
The Career Pathway: From Graduate to Professional Engineer
The initial career step for a graduate is typically an entry-level engineering position, often titled "Field Engineer," "Process Engineer I," "Rotation Engineer," or "Drilling Engineer Trainee." Many large operators and service companies have structured development programs where new hires rotate through different departments over 2-3 years. This provides a broad overview of the business and helps identify a long-term specialty.
For Monica Marquez, a critical early decision is choosing between working for an operator (the companies like ExxonMobil, Chevron, Shell that own the resources and production) and a service company (companies like Schlumberger, Halliburton, Baker Hughes that provide specialized technology and services to the operators). Operators often offer roles focused on long-term asset management and planning, while service company roles can be more field-intensive, technically specialized, and involve greater client interaction.
Regardless of the path, the first few years are for building foundational technical competence. This involves learning proprietary software, understanding company-specific standards, and, crucially, spending time in the field. An engineer who understands what happens on the drill floor or at a wellhead is infinitely more valuable than one who only works from models in an office. Safety training is paramount and non-negotiable. A deep, ingrained understanding of Process Safety Management (PSM) and personal safety protocols is the most important skill of all.
Professional licensure is a significant milestone. While not always mandatory in industry (compared to public sector civil engineering), becoming a Licensed Professional Engineer (PE) enhances credibility, is essential for certain consulting roles, and is often required for signing off on official designs or reports. The path involves passing the Fundamentals of Engineering (FE) exam shortly after graduation, gaining four years of supervised experience, and then passing the Principles and Practice of Engineering (PE) exam in your discipline.
Essential Technical and Non-Technical Skills for Longevity
Technical prowess alone is insufficient for a sustained career. The modern oil and gas engineer must cultivate a complementary set of non-technical skills.
Technical Skills remain the bedrock. These include advanced data analysis capability, proficiency in industry-standard software (e.g., Aspen HYSYS for chemical engineers, AutoCAD or SolidWorks for mechanical, Petrel for reservoir), and a solid grasp of geoscience fundamentals to communicate effectively with geologists and geophysicists. Understanding economics and project valuation is also critical, as every engineering decision has a cost implication.
Non-Technical Skills are the differentiators. Adaptability and Resilience are key in a cyclical industry subject to price volatility. Projects can be canceled, and priorities can shift rapidly. Cross-cultural communication is essential, as projects are global, and teams are diverse. The ability to explain complex technical issues to non-engineers—managers, financiers, community stakeholders—is a vital skill. Project management, even at a basic level, helps in delivering tasks on time and within budget. Finally, ethical judgment is paramount. Engineers must uphold the highest standards of integrity, especially when decisions impact safety, the environment, and public trust.
Industry Trends and Future-Proofing Your Career
The oil and gas industry is in a period of significant transition. A savvy professional like Monica Marquez must be aware of these trends to future-proof her career.
Digital Transformation and Analytics is the foremost trend. The industry is leveraging big data, machine learning, and automation to optimize production, predict equipment failures, and improve decision-making. Engineers who can work with data scientists, or who develop analytics skills themselves, will be in high demand.
The Energy Transition is the overarching macro-trend. The industry is increasingly focused on reducing its carbon footprint. This means engineers are now working on projects involving carbon capture, utilization, and storage (CCUS), blue hydrogen production (from natural gas with CCUS), geothermal energy development (using drilling and reservoir engineering skills), and biomethane from waste. Understanding these adjacent energy technologies makes an engineer more versatile.
Methane Emissions Management has become a major operational and regulatory focus. Engineers are tasked with detecting and fixing leaks across vast production and transmission networks using advanced monitoring technologies like satellites and drones.
Cybersecurity for operational technology (OT) is a growing concern. As drilling and production systems become more digitally connected, they become potential targets. Engineers need to understand secure system design principles.
The practical takeaway for any engineer is to be proactive about continuing education. This can mean taking short courses on specific new technologies, pursuing a master’s degree part-time, or obtaining certifications in project management (PMP) or data analytics. Staying technically curious and agile is the best defense against obsolescence.
