Study Notes
Structure of the Oil and Gas Industry
- The oil and gas industry consists of several key stages: exploration, development, production, transportation, refining, processing, and marketing.
- Market structures and pricing mechanisms are integral to understanding how prices are set in this complex industry.
Exploration and Development
- Oil and gas exploration begins with geological and geophysical surveys, with seismic surveys being the most effective technique.
- Challenges in exploration and reservoir development often involve economic and technological hurdles, requiring advanced tools and integrated seismic programs.
- Innovations in exploration and production (E&P) technologies include 3-D and 4-D seismic imaging, basin modeling, and slim-hole drilling, enhancing cost efficiency and reducing environmental impact.
- Drilling test wells is essential for verifying the presence of oil, representing a significant financial investment.
Economic Increases in Exploration Costs
- Major oil companies have witnessed over a 400% increase in exploration and production costs over the last 30 years, driven by activities expanding into newer regions, such as Africa and Asia Pacific.
- The estimated cost per drilled well was approximately $2 million in 2006, with costs in Western Europe nearly tenfold higher due to offshore operations.
Market Impact of Oil Prices
- Oil prices are closely linked to exploration and development costs, with rising prices since the 1970s leading to increased exploration investments.
- The number of wells drilled increased by 30% between 1980 and 2010; however, a decline in oil prices typically results in fewer exploratory well completions.
Production Process
- Oil production often occurs through natural pressure, with water or gas in the reservoir driving oil to the surface.
- Secondary recovery methods include water and gas injections, while enhanced oil recovery (EOR) techniques seek to maximize oil extraction.
- The production process encompasses various stages, from wellhead operations to storage and export, requiring specific facilities and utility systems.
Cost Structures in the Oil Industry
- Production incurs fixed costs (mainly exploration and development) and variable costs (operating costs), with variable costs typically lower than fixed costs.
- As production increases, the long-run average total cost (LATC) generally decreases, characterizing the oil industry as a "natural monopoly."
Market Dynamics
- Market size and government policies also influence the oil industry's structure, beyond just costs.
- Smaller fields may have higher operating costs, leading to an increase in LATC.
- In a perfectly competitive market, equilibrium prices are determined at the intersection of the supply curve (based on production costs) and the demand curve.
Refining Industry
- Crude oil refining involves multiple physical and chemical processes to produce finished oil products.
- The number of operational refineries globally rose from 646 in 1989 to 700 in 2008, spanning 120 countries, indicating growth in the refining sector.
- Historically, refining and the broader oil industry were dominated by major oil companies, shaping market operations and product availability.
