ABSTRACT:
It has been discovered that sticking caused by proppants used in a frac pack or gravel pack operation during hydrocarbon recovery efforts can be mitigated by placing a proppant anti-sticking fluid in a downhole space, such as an annulus adjacent a tool system or service tool. An operation is conducted that involves passing a carrier fluid including a proppant through the tool system. The carrier fluid is gelled and optionally crosslinked. The proppant anti-sticking fluid is flushed through the tool system to break the gel, contact the proppant and substantially clear the proppant from the tool system. Finally, the tool system is removed from downhole. The proppant anti-sticking fluid includes a diluent, such as an aqueous fluid, a brine, or a non-aqueous fluid, and an effective amount of a gel-breaking component to break the gel, and may, but does not necessarily include a surface tension-reducing compound, such as a surfactant.
