Wave Equation: Understanding the Earth and Finding Oil

Wave equations are equations that describe waves as they occur in nature. Waves in rivers, lakes, and oceans are similar to sound and light in appearance. In sciences like acoustics, electromagnetics, and fluid dynamics, the challenge of explaining waves arises. It simply refers to energy transfer over a medium. When you think of waves, you may picture swells and depressions. Waves aren’t limited to water, either. The powering of the waves, for example, can occur through a variety of mechanisms, such as the shifting of the Earth’s plates (plate tectonics) or sound generation. 

What are Seismic Waves?

Seismic waves, the same tool used to investigate earthquakes, are frequently employed deep beneath the Earth’s surface to search for oil and natural gas. These energy waves travel through the Earth in the same way as sound waves travel through the air. Seismic waves are transmitted deep into the Earth and permitted to bounce back in oil and gas exploration

The technique used to search for the Earth’s energy resources is called reflection seismology. When seismic waves are used to investigate earthquakes, the earthquakes are the source of energy, hence the origin of the waves. However, to use reflection seismology for oil and gas exploration, you must first establish some form of an appropriate source of energy on the Earth’s surface. They next disperse a sufficient number of seismic detectors around the Earth’s surface in order to record the radiated waves.

A shock wave is produced in seismic surveys by the following:

  • Thumper Truck: Crushes large plates into the ground (for exploration overland).
  • Compressed Air Pistol: Fires air pulses into the water (for exploration over water).
  • Explosives are detonated after being drilled into the Earth (for land exploration) or thrown overboard (for exploration over water).

The shock waves penetrate beneath the Earth’s surface and are reflected by the different rock strata. When geologists discover a potentially productive oil hit, they mark the area using GPS coordinates on land or marker flags on the sea.


How do Geologists Locate Petroleum Products?

Initially, geologists consider where oil and gas are formed. They create rocks like shale in deep-sea conditions. As a result, a geologist would begin by looking for shale. There are a few approaches to this:

  • One method is to examine the rocks exposed on the Earth’s surface. By creating a geologic map and extrapolating what we observe at the surface, we may arrive at a reasonable prediction about what rocks lie beneath
  • Drilling a core into the ground is another method for discovering what is under the surface. Cores can be hundreds of feet long and offer an image underneath a particular place. By drilling numerous cores kilometers apart, geologists can generate a picture of what exists underneath the surface.
  • A seismic survey is a third technique to learn about what is under the surface. Earthquakes generate natural waves that flow through the ground, and seismologists may investigate the earthquake itself and the features of the various strata of the Earth by monitoring them. Researchers know the outer core is liquid in significant part because of earthquakes

How Deep do Oil Reserves Go Underground?

The average depth of oil wells dug in 1949, the first year for data, was 3,635 feet. According to the most current data available, an average of 5,964 feet had been drilled by 2008, a minor reduction from the previous year’s total of 6,064 feet.

Which Country has the Most Extensive Oil Reserves?

The globe produced approximately 100 million barrels of oil per day in 2018, according to the latest IEA figures. These are the top five oil-producing countries that account for more than half of global crude oil production: Venezuela, Saudi Arabia, Canada, Iraq, and Iran. 

How Much Oil is Left on the Planet, and how Long will it be Obtainable?

International oil consumption rates are five barrels of oil (199 gallons) per individual per year (based on the 2016 world population of 7,464,022,049 people), or 0.5 gallons per capita each day. As of 2016, the globe consumed 35,442,913,090 barrels of oil, or 97,103,871 barrels a day. 

There are health, environmental, and political reasons to minimize our reliance on oil and petroleum. Understanding what items are derived from oil is the first step in minimizing oil usage. Once we are aware of the problem of oil consumption and the items that use it, the solution does not appear to be simple. Plastics, for example, may be manufactured from materials other than oil, such as maize or hemp. Investigate such items and lobby politicians to support them.
