A drilling technology in which NATURAL GAS is extracted from large deposits of impermeable rock formations known as shale, deep within the earth's crust. This drilling technique involves injecting large volumes of high-pressure fracturing fluid (a mixture of water, sand, and chemicals) several thousand feet underground, thereby creating cracks or fissures in the shale formation, and releasing trapped gas
Patterns (real or mathematical) which look similar at different scales, for example the network of airways in the lung which shows similar branching patterns at progressively higher magnifications. Natural fractals are self-similar across a finite range of scales while mathematical fractals are the same across an infinite range. Many natural, including biological, structures are fractal (or fractal-like). Fractals are related to "chaos" (see NONLINEAR DYNAMICS) in that chaotic processes can produce fractal structures in nature, and appropriate representations of chaotic processes usually reveal self-similarity over time

Separation of a mixture in successive stages, each stage removing from the mixture some proportion of one of the substances, for example by differential solubility in water-solvent mixtures. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
