The ,fluid, contains sand which holds open the newly created fractures. The gas then flows back through the well, up to the surface for collection. Once gas collection is complete, the ,fluid, used is also returned to the surface for collection (this is known as ,flowback fluid,). Concerns around unconventional oil and gas extraction include:
