What is fracking?

are you curious about how we extract oil and gas from rocks deep underground let's break down fracking fracking short for hydraulic fracturing is a technique developed in the 1940s to extract oil and gas from underground rock formations so how does it work imagine rocks that are so tight oil and gas can't flow through them easily was that's where fracking comes in first a high press fluid mix of water sand and chemicals is injected into of the rock via a wellbore this creates fractures or expands existing ones forming a network of cracks the sand in the fluid keeps these fractures open allowing oil and gas to move freely this process can take a few days but results in significantly increased permeability of the rock once fracking is done the well is ready for long-term extraction potentially producing oil and gas for many years and there you have it a quick dive into the world of fracking got more questions drop them in the comments below
