Abstract
In stimulation treatments to increase the production of hydrocarbons from subterranean formations, especially in treatments including hydraulic fracturing followed by gravel packing, desirable short wide fractures are created and filled with proppant by deliberately including in the first fluid/proppant slurry pumped a sufficiently high concentration of a bridging-promoting material, such as fibers, that reduces the mobility of the slurry when it dewaters so that screenout at or near the tip occurs.
