How is shale gas processed

In 50 years, most of our resources will be gone. Switching to renewable sources of energy is a process, and we consider natural gas and shale gas as a bridge solution between now and the future. What are the advantages of using natural gas compared to other fossil fuels? What is shale gas, where does it come from and how do we extract it? What is the difference between shale gas and natural gas? Before we answer these questions, you might want to read our article about the pros and cons of fossil fuels.

Shale is a fine-grained, clastic sedimentary rock, composed of mud and it is a massive mineral. It is so tough that drilling into it is a rather costly process. Shale gas is hiding beneath this kind of rock, deep below the surface. While conventional gases are easy to extract and trapped under a permeable layer of rock, extracting unconventional gases is a really hard process.

They are more than 4 kilometres below the surface, making it really difficult to produce them. Shale gas has the same composition as natural gas.
