A new proppant now available for use has properties that make it an ideal replacement for sand and glass beads in formations where there is high closure stress or the need for sand control. The proppant, called super sand, is made by coating ordinary frac sand with a resin that is dry and hard at ordinary temperatures. It mixes readily with frac fluids and pumps easily. Inside the fracture, it softens to a glassy state from the reservoir temperature or added heat, then cures and hardens. It fills the fracture with a strong, cohesive rock that retains high permeability at stresses up to 100,000 psi. Laboratory tests and field experience indicate super sand has excellent long-term stability since the resin coating is inert to the most common oil-field chemicals, acids, and high temperature water.
