Study Notes
Early Days of the Oil and Gas Industry
- The first successful oil well, drilled by Edwin Drake, was completed on August 27, 1859.
- This marked a significant step towards replacing whale oil.
- Early oil production sites differed in location and characteristics from modern facilities.
- Artificial lift methods have been essential to the upstream sector since its inception.
Three Oil and Gas Industry Sectors
- The oil and gas industry comprises three main sectors: upstream, midstream, and downstream.
- The upstream sector focuses on exploring and extracting crude oil and natural gas.
- The midstream sector processes, stores, markets, and transports crude oil, natural gas, and natural gas liquids (NGLs).
- NGLs include ethane, propane, butanes, and sulphur.
- Midstream companies connect oil and gas production sites with consumers.
- The downstream sector encompasses oil refineries, petrochemical plants, and retailers of petroleum products and natural gas distribution.
- Downstream products include gasoline, diesel, jet fuel, heating oil, asphalt, lubricants, synthetic rubber, plastics, fertilizers, antifreeze, pesticides, pharmaceuticals, and natural gas propane.
Upstream Sector: Drilling and Reservoir Types
- The upstream sector starts with drilling operations for exploration and production.
- The common reservoirs in the U.S. include oil, volatile oil, dry gas, and gas condensate.
- Each reservoir type has unique characteristics, producing different hydrocarbon mixtures.
- Formation pay zones vary, which influences exploration and production decisions.
Upstream Sector: Well Types
- Common well types include conventional gas, shale gas, coal bed methane, and tight gas wells.
- Unconventional wells (like shale gas) require special techniques like fracturing.
Upstream Sector: Artificial Lift
- Artificial lift systems are used when natural reservoir pressure is insufficient.
- These systems enhance production by raising fluids to the surface, mitigating pressure constraints.
- Pumping units maintain production as natural reservoir pressure diminishes.
Dual-Completed Wells
- Dual-completed wells extract resources from two different formations using a single wellbore and wellhead.
Well Completion: Perforation
- Wells are perforated to allow reservoir fluids to enter the wellbore.
- The perforation process often occurs during well completion.
Oil Well Stream Composition
- Oil wells produce a mix of oil, water, gas, and potentially other substances.
- The oil-to-water and fluid-to-gas ratio defines whether a well is classified as an oil well or a gas well.
Natural Gas Composition
- Natural gas contains methane, ethane, propane, butanes, pentanes, and various trace elements.
Different Pressure Measurements
- PSIA (pounds per square inch absolute) and PSIG (pounds per square inch gauge) are common pressure units.
- PSIA is more significant in midstream, whereas PSIG is often used in upstream operations.
Top Forms of Energy Production in the US
- Top energy sources in the U.S. include petroleum, nuclear, natural gas, hydro, wind, solar, geothermal, biomass, and wood.
