105 . A method of treating a subterranean formation, the method comprising:
placing in the subterranean formation a composition comprising energetic cocrystals, each energetic cocrystal independently comprising
an energetic compound; and
a secondary material.

106 . The method of claim 105 , wherein placing the composition in the subterranean formation comprises placing the composition in at least one of a fracture, at least a part of an area surrounding a fracture, a flow pathway, an area surrounding a flow pathway, and an area desired to be fractured.

107 . The method of claim 106 , wherein the method further comprises hydraulic fracturing to generate the fracture or flow pathway.

108 . The method of claim 105 , wherein the method comprises a method of approximately measuring at least one dimension of a fracture or flow pathway in the subterranean formation.

109 . The method of claim 105 , further comprising detonating at least some of the cocrystals downhole.

110 . The method of claim 109 , comprising triggering the detonating.

111 . The method of claim 110 , wherein the triggering comprises exposing at least some of the cocrystals to at least one of a compression wave, a chemical activator, heat, pH change, pressure, friction, passage of time, and vibration.

112 . The method of claim 109 , wherein the detonating is sufficient to generate a compression wave downhole at least partially within a fracture or flow pathway, wherein the method further comprises using the compression wave to measure at least one characteristic of the fracture or the flow pathway.

113 . The method of claim 112 wherein the measured characteristic comprises at least one of length, height, width, volume, surface area, shape, degree of closure, and time of closure.

114 . The method of claim 112 , wherein using the compression wave to measure the characteristic comprises using a compression wave detector to approximately determine at least one dimension of an area surrounding the composition placed in the subterranean formation.

115 . The method of claim 114 wherein the compression wave detector is located at least one of downhole or above the surface.

116 . The method of claim 105 , wherein the composition further comprises a carrier fluid.

117 . The method of claim 105 , wherein the composition further comprises a viscosifier.
