As a trusted natural gas supplier, we often get asked: “Where does natural gas come from, and how is it brought to our homes and businesses?” The answer lies deep underground—and in the science and innovation that makes safe extraction possible. Let’s take a closer look at how natural gas is formed and extracted.
The Origins of Natural Gas
Natural gas is a fossil fuel that formed millions of years ago when ancient plants and animals were buried under layers of sediment. Over time, pressure and heat transformed this organic material into hydrocarbons—chemical compounds that include methane, the main component of natural gas.
These hydrocarbons collect in porous rock formations deep beneath the Earth’s surface. But they don’t just sit there waiting to be scooped up. They’re often trapped under layers of rock or clay that prevent them from rising naturally. That’s where modern extraction techniques come into play.
The Extraction Process
-
Exploration & Drilling
The journey begins with geologists using seismic surveys to locate underground natural gas reserves. Once a site is identified, drilling equipment is used to bore a well—sometimes thousands of feet deep—into the rock that holds the gas.
-
Hydraulic Fracturing (Fracking)
In many shale formations, the gas is trapped in tight spaces. To release it, a process called hydraulic fracturing is used. This involves injecting a mixture of water, sand, and small amounts of additives into the rock at high pressure. The result: tiny fractures in the rock that allow the gas to flow freely into the well.

Collection & Processing
Once the gas reaches the surface, it’s separated from water and other byproducts. It’s then processed to remove impurities like carbon dioxide, sulfur, and water vapor. What’s left is clean, ready-to-use natural gas that can be delivered to homes, schools, and businesses.
Responsible and Safe Extraction
At every step, safety and environmental responsibility are top priorities. Modern drilling sites are designed to protect groundwater and limit emissions. Regulations and continuous monitoring help ensure operations remain safe for workers, surrounding communities, and the environment.
