Describes test apparatus, test conditions, and procedures for use in evaluating the short term conductivity of fracture proppants under standard laboratory conditions. These recommended procedures may be used to evaluate and compare the short term conductivity of packs of proppant samples under laboratory conditions, but are not intended for use in obtaining absolute values of proppant pack conductivities under downhole reservoir conditions. The effects of fines, formation temperature, formation hardness, resident fluids time, and other functions are beyond the scope of this publication.
