Abstract
The invention discloses a method of effecting fracturing in a subterranean formation utilizing substantially constant density fluids whereby proppant segregation is minimized or eliminated within the formation. Fluid density is adjusted by varying the salt content or addition of a gas or gasifiable liquid or both as proppant is added to the treatment fluid.
