Let's take a look at what hydraulic fracturing is and what it's used for.
Answer: a. Natural gas
Step-by-step explanation:
Hydraulic fracturing, also known as fracking, is a technique used in the oil and gas industry to extract natural gas and oil from underground rock formations.
The process involves drilling a well into the rock formations deep beneath the Earth's surface.
Next, a high-pressure mixture of water, sand, and specific chemicals is injected into the well. This fluid creates cracks in the rock, allowing trapped natural gas or oil to be released.
To ensure the fractures remain open, sand or other similar materials are added to the fluid. These substances keep the fractures from closing once the pressure is reduced, allowing the gas or oil to flow freely.
Once the fracturing process is complete, a portion of the injected fluid, along with the extracted natural gas or oil, is recovered from the well and brought to the surface for further processing and/or disposal.
