Abstract:
1. A single component proppant particle for use in hydraulic fracturing, wherein a fracturing fluid is inserted into a rock formation to create a hydraulic fracture, the particle being formed from a single bulk material and having a substantially cylindrical shape with closed ends and a single wall structure defining a transverse dimension and a longitudinal dimension of the particle and a single internal void space within the particle, the void space also having a transverse dimension that is at least 0.2 times the maximum transverse dimension of the particle; the wall structure providing the particle with sufficient strength to withstand hydrostatic pressure of the fracturing fluid and closing pressures from the formation; the wall structure being formed of a material that is substantially impervious to the fracturing fluid.
