Abstract

Ceramic proppants are determined as material designed for hydraulic fracturing in the shale gas industry. Shale formation is fractured due to pumping the fracturing fluid including proppants into the unconventional well. Ceramic granulates set in the newly created fissures act as a prop and permit the shale gas of flowing up the well. The aim of this research was to study and compare ceramic materials used as proppants. The investigation includes four kinds of industrial proppants in green state obtained in a way of mechanical granulation process without binder and with poly(acrylic–styrene) dispersion in amount of 5 mass% with respect to the powder. Green pellets and afterward sintered granulates with 16/20 and 20/40 mesh were also analyzed and compared. Usefulness of green pellets was estimated basing on bulk density, thermal analysis, thermogravimetry, roundness coefficient and porosity results. Structure, morphology and chemical composition of the green state samples were determined by scanning electron microscopy with energy-dispersive spectroscopy. The sintered proppants were also characterized with X-ray tomography, turbidity and solubility in acid. Mechanical strength of these samples was established during subjection to crush test. The outcomes show a suitability of the studied material and prove chemical composition and grain size influence on the integrity of created fractures and therefore the extraction of the unconventional gas out of the well.
