Modeling Oil and Gas Reservoirs Activity Source: Adapted with permission by the American Association of Petroleum Geologists from AGI’s EarthComm, Earth’s Natural Resources, pp. R65-R66. This activity will help you to understand some of the factors that petroleum geologists need to consider when deciding where to recommend drilling for oil. Since people use petroleum products for energy and as source materials for petrochemicals, it is important as citizen scientists to understand the science and technology behind the search for oil and natural gas.

Natural Gas Formation Activity Source: Adapted by AAPG from the American Geosciences Institute. Adapted with permission. Natural gas, which is mostly methane, is an energy resource used for generating electricity and heating, powering transportation, and manufacturing products. Right now, one-quarter of the world’s energy comes from natural gas. Natural gas formation, one of the processes occurring on our ever-changing Earth, takes a very long time. Natural gas is formed from marine organisms that die, sink to the bottom of the ocean, and get covered with sediments. [Read More]

Oil Trap Model Activity Source: Geological Society of America. Adapted with permission. Crude oil is a liquid hydrocarbon that is thought to have formed from the accumulation and burial of mostly marine organisms in a low-oxygen environment. This environment prevents decay of the organisms, trapping the organic matter and converting it to hydrocarbons. Because oil is a liquid that is lighter than water, it naturally rises through the pores of rocks in which it forms towards the surface. [Read More]

Painting With Soil Activity Source: Soil Science Society of America, Adapted with permission Soils are one of our most important natural resources — just think of where all the food you eat comes from. They also are important for the beauty the many soil colors add to our landscapes. Most of us overlook this natural beauty because we see it every day. Often these colors blend with vegetation, sky, water, etc. [Read More]

Parks Past, Present, and Future Activity Source: Adapted with permission by National Park Service. Over Earth’s 4.5 billion-year history, tectonic upheavals and colliding plates formed mountain ranges and carved out basins. Forces of erosion and weathering have been at work to break down these landforms. Records of these processes are imprinted on the land and define distinctive landscapes around the United States and in its national parks. The dynamic processes that formed the spectacular landscapes of many national parks remain active today. [Read More]

Particle Size and Oil Production Activity Source: Adapted by AAPG from EarthComm and the American Geosciences Institute. Adapted with permission. What factors affect how easily a fluid can move through sediments? How is this flow rate connected to oil production? Many people think that oil lies in big pools below Earth’s surface. Oil actually is located in the pores within rocks (called “source rocks”). When the pores are connected, oil can flow slowly through the rock. [Read More]

Products from Petroleum Activity Source: Society of Petroleum Engineers. Adapted with permission. Where would we be without petroleum? You can kiss lipstick goodbye! Not only does petroleum provide fuel to run our vehicles, cook our food, heat our homes, and generate electricity, it is also used in plastics, medicines, food items, and countless other products, from aspirin to umbrellas and, yes — lipstick! We use many oil products as synthetic alternatives to natural materials, including synthetic rubber instead of natural rubber, and detergent instead of soap. [Read More]

Products Made from Petroleum Activity Source: Adapted with permission by Bruce Wells, American Oil & Gas Historical Society. Background Most people associate petroleum with transportation — but we are surrounded by thousands of other everyday products that come from this vital natural resource. A typical 42- gallon barrel of crude oil yields about 20 gallons of gasoline and 4 gallons of jet fuel. What products come from the other 18 gallons? [Read More]

Properties of Fluids in Reservoirs Activity Source: American Association of Petroleum Geologists. Adapted with permission from EarthComm , American Geosciences Institute. Petroleum geologists play a vital role in locating energy resources. They use a variety of methods to collect the data they need to find reservoirs of oil and natural gas. When they find these reservoirs, petroleum geologists need to calculate their volume. They also need to estimate how much they can recover (remove) from the reservoir. [Read More]
