Drilling Basics


What’s the only way to be sure you’ve found oil?

Despite all the amazing technology available today, the only way to be sure you’ve found an underground reservoir is to drill a well. It’s as simple as that.

Drilling for hydrocarbons isn’t an easy prospect, though.

To overcome the challenges that go along with drilling, scientists and engineers have had their work cut out for them. Here are some of the questions they’ve had to answer.

What is the best way to reach an oil and natural gas reservoir from the surface?
What is the purpose of drilling mud?
What information can be gathered while the well is being drilled?
How is it possible to drill a horizontal well?
How is it possible to drill for oil in the deep ocean?

Luckily for us, scientists and engineers have put modern technology to good use and found the answers to these questions. Wells are being drilled to incredible depths, deepwater reservoirs are being tapped, and multiple reservoirs are being harvested from a single borehole.
