16/6/2017, · The sand stays put in the cracks, creating pathways for oil and gas to travel towards the well, and about 40% of the water and chemicals flow ,back, to the surface. Some of the chemicals in fracking ,fluid, are not harmful. Others are toxic. Most are present in very small quantities, but even in tiny amounts chemicals like benzene are dangerous.

15/1/2018, · Mechanism. Hydraulic ,fracturing, is the process of pumping ,fluid, into a wellbore at an injection rate too high for the formation to accept without breaking. During injection, the formation’s resistance to flow increases, and the pressure in the wellbore increases to a value called the break-down pressure, which is the sum of the in-situ compressive stress and the strength of the formation.

What is hydraulic fracturing? - USGS

Hydraulic fracturing,, informally referred to as “fracking,” is an oil and gas well development process that typically involves injecting water, sand, and chemicals under high pressure into a bedrock formation via the well. This process is intended to create new fractures in the rock as well as increase the size, extent, and connectivity of existing fractures.
