Horizontal Drilling: How It Works and Why It Matters

Imagine standing on a broad oilfield with the knowledge that oil and gas lie deep underneath, trapped in tight rock. The challenge is that the reserves are hard to get at. This is where horizontal drilling flourishes, making possible the extraction of oil and gas that were considered too hard.

What Is Horizontal Drilling?

Horizontal drilling allows drilling that is set horizontally-an alternate form of drilling, letting the drill bit turn sideways after drilling down. Because of this method, along with hydraulic fracturing, the oil and gas industry has been revolutionized to economically extract hydrocarbons in difficult settings.

How It Works

We begin from drilling downwards like normal:

• Drilling Down: The process starts like normal drilling. A hole is drilled straight down into the earth.
• Turning the Drill: At a certain depth, the drill starts to turn sideways.
• Going Sideways: The drill continues moving sideways through the oil-rich rock, sometimes for miles.
• Extracting Oil and Gas: Once the drilling is done, the oil and gas start flowing through the well to the surface.

Why Is It Important to Oil and Gas Companies?

The application of horizontal drilling opened a new revolution for the whole upstream oil and gas industry. One horizontal well could replace innumerable vertical wells, each one tapping much of the underground area. This meant high production with a low land footprint.

Think of oil under your feet as being shaped like a giant pancake. By drilling vertically downward you would access only a small portion of it. Whereas horizontal drilling taps into a far larger section, therefore becoming remarkably efficient.

Key Benefits of Horizontal Drilling

Among the many real benefits of this method are:

• More hydrocarbons recovered from one well.
• Less land impact, as fewer wells are needed.
• Less money spent, as companies save on drilling and sustaining.
• Access to oil and gas resources considered unreachable.
• The Revolution in the Oil and Gas Business

Horizontal drilling has greatly altered the landscape of the oil and gas business. Fields considered to be empty are now being worked once again. Countries became less dependent on foreign oil. For some places, like the Permian Basin in the U.S., the economic boom provided by this method has been unreal.

It’s not just oil; horizontal drilling has also provided the free rein for bringing in large amounts of cleaner natural gas in competition against coal. Today, more clean energy sources are required, and with the outside world in search of such energy, horizontal drilling has in its own way played a part.

What Awaits?

Despite the benefits, there are some downsides to horizontal drilling. It requires high capital investments, skilled workforce, and the latest technology. The investment pays off for an oil and gas company that is willing to face the challenges.

Conclusion

Horizontal drilling offers many benefits, but it also has many other challenges. It requires a lot of investment, skilled workers, and advanced technology. However, for oil and gas companies ready to tackle these challenges, the benefits far exceed the costs.

One thing is certain as the industry moves forward: Horizontal drilling will not fade away in a hurry. It is the key to more efficient extraction of oil and gas. Next time you look at an oil rig, think: it’s not just drilling down, it’s reaching out, pulling energy from deep under the ground.
