Then as it flows down the pipe, we want the fluid to gel up to support the proppant and flush it deep into the fractures. Then the gel has to break down so we can flow back and recover the fracking fluid, but leave the proppant behind. This means we need a chemical process to produce, and then break, the gel cross-linking at a predictable rate.
