The oil and gas are stored in the pore of underground rock. In order to explore this sources, wells are drilled to connect reservoir by hydraulic fracturing techinic, this fracturing process is to pump fluid down a well at strong pressure to make the fractures, meanwhile, the proppant is transported to prop the open after high-pressure pumping stops. Because of the proppant-filled fracture channel can make oil and gas flowing more freely, it will increase the production. According to date ...
