Natural gas plays a crucial role in the global energy mix — but how do we actually get it from deep underground to your stove or power plant? Here’s a simplified step-by-step look at the process:
- Exploration
Geologists and geophysicists use seismic surveys and well data to locate potential gas reservoirs beneath the surface. - Drilling the Well
A drilling rig is used to reach the gas-bearing formations. Depending on the depth and formation, vertical or horizontal drilling may be used. - Casing & Cementing
Steel pipes (casings) are inserted into the well and cemented in place to prevent collapse and protect groundwater. - Well Logging & Testing
Tools are lowered into the well to collect data on rock and fluid properties. Formation tests help determine the gas potential. - Completion
Perforations are made in the casing at the reservoir level to allow gas to flow into the wellbore. Additional stimulation (e.g., hydraulic fracturing) may be done to enhance flow. - Production Begins
Gas flows to the surface through the wellhead and is sent through separators to remove water and impurities. - Gas Processing
At a gas plant, impurities like H₂S, CO₂, and NGLs (natural gas liquids) are separated. The remaining methane is what becomes pipeline-quality gas. - Transportation
Processed gas is transported via high-pressure transmission pipelines to end users — homes, industries, or power plants. - Storage & Distribution
Gas may be stored in underground reservoirs to manage supply and demand, and later distributed through local utility networks. - Monitoring & Abandonment
Throughout the well’s life, continuous monitoring ensures safety and efficiency. Once depleted, the well is sealed and the site is restored.
