Реферат: ABSTRACT A production well is completed through a subterranean oil or gas reservoir. The well employs a well casing with perforation tunnels for fluid communication with the reservoir. A sand screen tubing is located in juxtaposition with the perforation tunnels with an annular section being formed between the casing and the sand screen tubing. A fracturing fluid and gravel packing sand is injected through the annular section and perforation tunnels into the reservoir. The injection is terminated when the fracture is complete and the perforation tunnels and annular section are filled with gravel packing sand. The oil or gas in the reservoir is then produced through the gravel packed well casing and the sand screen.
