Most people know that hydraulic fracturing for oil and natural gas is controversial, but not so many know what it really means. So here is an overview of the “fracking” process, frac equipment, and the roots of the controversy.
Fracturing uses pressurized fluid to create cracks in layers of rock surrounding a drilled shaft. This is done because there is often a great deal of oil and natural gas scattered in small pockets underground. These cracks allow the dispersed material to be extracted.
The fluid used in fracking is mixed with sand, called proppant, which helps keep fractures open when pressure is released. Moving sand to be mixed with the fluid is a significant logistical challenge, and requires a specialized mobile conveyor/blender and frac sand storage equipment.
Frac sand is loaded into large holding units called frac sanders. Heavy duty mobile conveyor systems, called T belt conveyors, carry the sand to be mixed with fracking fluid as it is pumped down the well. Many frac jobs require in excess of 1,000 tons of sand.
Enough fluid and sand are pumped in to cause cracking throughout the surrounding area. When the cracking is done, the fluid is pumped out of the well and piped to treatment facilities. The oil or natural gas can then be easily extracted.
Controversy over fracking comes from a few different areas. In some cases, natural gas has been released in high concentration into groundwater or the atmosphere. This can create health problems for people who consume it. Secondly, waste water removed from the well has been mishandled, often due to poorly constructed piping, releasing chemicals into the environment. Finally, positioning the large frac sand storage containers and other frac equipment can leave scars on surrounding land.
Whether you’re for or against hydraulic fracturing it’s good to know some background. So next time it comes up in a heated conversation, you can talk about it with some solid understanding about what it really means.
