Nov 16, 2012Fracturing fluid is made up of a base fluid, proppant, and chemical additives. Water accounts for about 90 percent of the fracturing mixture and sand accounts for about 9.5 percent. Chemicals account for the remaining one half of one percent of the mixture. The base fluid applies pressure to the formation and delivers the proppant to the fractures.

Hydraulic fracturing is used in the oil and gas industry to increase the flow of oil and/or gas from a well. Proppants are pumped into the oil well with fracturing fluid to hold the fissures open. The proppant size, shape, and mechanical strength influences the integrity of the newly created fractures, and therefore the flow of oil and gas out of the well.

Many formations are too tight to produce oil and natural gas, and require a stimulation process to extract the resources. In hydraulic fracturing, fluids carrying proppant are pumped into the ground with enough pressure to crack the rock. The proppant is left behind to hold open the cracks, while the fluid is flowed back allowing oil and gas

Hydraulic fracturing is a technique developed initially to stimulate oil production from wells in declining oil reservoirs. With technological advances, hydraulic fracturing is now widely used to initiate oil and gas production in unconventional (low-permeability) oil and gas formations that were previously uneconomical to produce.

Hydraulic fracturing has gained a lot of attention recently, as companies scramble to mine the valuable frac sand contained in the Midwest. While fracing is new to most people, hydraulic fracturing, though in primitive form, can be traced all the way back to the 1860's oil industry, when liquid nitroglycerin (NG) was used to stimulate shallow rock wells in several states around the US.

Proppant is a gritty material with uniformly sized particles that is mixed in with fracturing fluid during the hydraulic fracturing (fracking) process to hold open fractures made in the ground. There are a variety of different types of proppant, including naturally occurring sand and man-made proppants. Man made proppants include materials such as resin-coated sand or strong ceramic materials.

Hydraulic fracturing (HF) is a well stimulation process used to maximize the extraction of underground resources – oil, natural gas and geothermal energy. The HF process includes the acquisition of water/mixing of chemicals, production zone fracturing, and HF flowback disposal. In the United States, HF has been used since the 1940's.
