Abstract
Improved fracture propping agents and methods of using such agents are provided. The propping agents are basically comprised of a plurality of small pieces which are suspendable in a fracturing fluid and have adequate compressive strength to prevent the closure of a fracture into which they are carried. The propping agent pieces have passageways formed therethrough containing a dissolvable substance whereby when the substance is dissolved, the permeability of the propping agent to the flow of formation fluids is increased.
