Abstract:
1. A multiple component proppant particle for use in hydraulic fracturing, wherein a fracturing fluid is used to create and is inserted into a hydraulic fracture, the multiple component proppant particle comprising: a boat component that includes a wall structure defining a transverse dimension and a longitudinal dimension of the boat component and one or more internal void spaces within the boat component, each void space also having transverse dimensions, such that the total transverse dimension of the void spaces is at least 0.3 times the maximum transverse dimension of the boat component; the wall structure being formed of a material that is substantially impervious to the fracturing fluid and providing the particle with sufficient strength to withstand hydrostatic pressure of the fracturing fluid; and one or more structural components produced separately from and attached to the boat component by adhesively bonding to form the multiple component proppant particle, the structural component providing the multiple component proppant particle with sufficient structural strength to stop the fracture from fully closing; wherein the multiple component proppant particle has a density that is substantially similar to the density of the fracturing fluid.
