From prop +‎ -ant.


  • Carbo Ceramics is a leader in making what's called ceramic proppant, which is the synthetic material, sand-based often, with chemicals that are injected into the fractured rock to hold open the cavities so the natural gas goes up into the piping that captures it.

  • Carbo Ceramics makes ceramic proppant, which is used by the exploration and production industry during the hydraulic fracturing process.

    Carbo Ceramics Sees Rebound In 2010

  • Inside the fluid is mixed with the "proppant," which is typically sand, aluminum pellets or some other small granular material that is carried into the fractures and is left to prop the crack open, thereby allowing the oil or gas to flow. Chronicle

  • Because of this, the solid is known as a 'proppant'.

    The Engineer - News

  • "A granular material, called proppant, is suspended and transported in the fluid and fills the fracture, 'propping' it open once high-pressure pumping stops.


  • Even before Middle East turmoil boosted oil prices, revenues and profits were surging for Carbo, which dominates the market for ceramic proppant, used in shale-oil and gas production.

  • Sand, the proppant, primarily quartz and feldspar aka ground up rock, is the material that gets lodged in cracks that open up, and keep those cracks open when force and pressure are removed, allowing less resistance between underground hydrocarbons, to allow them to become newly liberated hydrocarbons, which we use to power a significant portion of our country.

  • Frac jobs are used to increase the flow of hydrocarbons from a well by pumping into it frac gel, a chemical-laden fluid that carries a coarse proppant to hold open those fractures created by pumping into the productive formation.

  • The well will be completed using a plug and perforation process in 15-stages that is expected to involve the placement of approximately 3,000,000 pounds of proppant into the Niobrara Formation.

  • So far in 2011, more than 1,200 stages have been pumped globally, saving over 60,000 tons of proppant compared to standard fracturing techniques.
