Frac Sand as a "Proppant"
AUTHOR:admin PUBLISHED:2016-03-09 CLICK:正在读取

When the pumps are turned off, the fractures deflate but do not close completely - because they are propped open by billions of grains of frac sand. This only occurs if enough sand grains to resist the force of the closing fractures have been delivered into the rock.

The new fractures in the rock, propped open by the durable sand grains, form a network of pore space that allows petroleum fluids to flow out of the rock and into the well. Frac sand is known as a "proppant" because it props the fractures open.

Other materials that have been used as a proppant include ceramic beads, aluminum beads and sintered bauxite. Frac sand generally delivers the highest level of performance and it is currently the proppant most frequently used by the petroleum industry.
