Natural gas is one of the most important energy sources in the world today. It heats homes, cooks food, and powers factories across the globe. But where does this fossil fuel come from, and how are natural gases extracted?
Keep reading to learn how natural gas is extracted from the ground and how landowners can make informed decisions about their mineral rights.
Most natural gas produced in the U.S. is extracted domestically. The process of gas extraction depends on where the natural gas formed underground and what type of rock formation holds it. Companies use different techniques to bring raw natural gas to the earth's surface:
Conventional natural gas deposits sit in large underground pockets within porous rock formations. Vertical drilling is the simplest way to extract this gas. A drill rig creates a straight hole down into the ground until it reaches the gas reservoir. Once the drill reaches the natural gas deposit, steel pipes called casings are installed and the gas is extracted through them.
Hydraulic fracturing (also called fracking) is a modern method used to extract natural gas from tight rock formations like shale. Fracking starts after a well is drilled into the rock formation containing the shale gas. High-pressure pumps push a mixture of water, sand, and chemical additives down the well. This pressure releases the natural gas that’s contained in the rock.
Horizontal drilling is an innovative technique that works alongside hydraulic fracturing to access more natural gas with fewer wells. Instead of just drilling straight down, the well starts vertically but then turns to drill sideways through the rock layer that contains the gas. This method allows companies to reach natural gas across a much larger area from a single drilling pad on the earth's surface.
Natural gas occurs naturally in some coal deposits. Companies can drill into coal seams and reduce the pressure to release methane trapped in the coal. This method sometimes uses water pumping or limited hydraulic fracturing.
When drilling for oil, companies often find natural gas sitting on top of an oil reservoir. This associated natural gas can be captured and sent through natural gas pipelines or processed on-site.
In older wells where production has slowed, companies inject gases like carbon dioxide or nitrogen into the formation. This maintains pressure and pushes more natural gas toward the production wells, extending the well's productive life.
There are many factors that can play a role in the value of your mineral rights, and while it’s possible that extraction methods could become a part of a negotiation, this is unlikely to be a major value influence for a few reasons. Most importantly, experts have weighed in that in countries with fewer conventional deposits remaining, investment in unconventional natural gas extraction is a major market. This means that the United States' unconventional deposits are staying competitive with conventional extraction sites in the Middle East.
While the extraction method may be less important, one aspect of your mineral deposit that may influence the value of your rights may be whether the deposit is wet or dry. Wet natural gas is a combination of natural gas liquids, like propane, and water vapor. While it can be more complex to have wet natural gas processes, this gas may be worth more because natural gas liquids are particularly valuable.
Many landowners wonder if their property sits on top of valuable natural gas energy deposits. While you cannot see natural gas thousands of feet below ground, several practical steps can help you determine if your property has potential:
Before exploring, verify that you actually own the mineral rights to your property. Many landowners discover that previous owners sold or retained mineral rights separately from the surface land. Knowing your legal standing prevents costly mistakes and allows you to benefit from any natural gas discovered on your land.
Check if your land is located near existing gas wells or proven gas fields producing natural gas. Review county records for historical drilling activity and contact your state's geological survey office for maps showing known gas formations.
Professional geologists have the training and tools to accurately assess your land's potential. These experts interpret complex data that reveals where gas might be trapped.
Physical samples from your property can provide clues about underground resources. Geologists can examine soil composition to identify substances associated with natural gas deposits.
Some surface features can indicate underground gas deposits. For example, this might include natural gas seeps that reach the surface. However, these signs are rare and not definitive proof, so professional surveys remain important.
Once you know enough natural gas exists on your land to be valuable, you may wonder if you should keep your mineral rights or sell them. Although this decision depends on your financial goals, risk tolerance, and personal circumstances, some of the reasons to sell mineral rights include:
If you decide selling makes sense, following the right steps can help you get fair value for your oil and gas mineral rights:
Natural gas extraction has evolved over the decades. Modern methods like hydraulic fracturing and horizontal drilling now make it possible to reach natural gas deposits that were once impossible to access.
For landowners, understanding these extraction processes helps in making informed decisions about mineral rights. Whether you choose to lease your property or sell mineral rights, knowing how companies will access the natural gas beneath your land is valuable.
