Mazzara, V B; Fesperman, J M

Oil-soluble prilled resins are characterized by the freedom from an oil-insoluble resinous residue. The use of such resins in the fracturing of crude oil formations is described. Substantially spherical oil-soluble propping particles for use in fracturing undergrouond oil or gas formations comprise polymerized alicyclic olefinic hydrocarbons containing anti-oxidants which inhibit the formation of oil-insoluble residue in such particles. The oil-soluble spacer particles are uniformly mixed in a suitable liquid carrier, usually water, with the propping agents and pumped into the formation to be fractured. In the fracture, the spacer particles and the propping agents are particles substantially uniformly distributed. (5 claims)
