Preparing a treatment fluid comprising a base fluid and magnetic proppant particulates, wherein the magnetic proppant particulates comprise proppant particulates at least partially coated with a stabilization agent and magnetic particles, and preparing a spacer fluid comprising a base fluid, a gelling agent, and a breaker. Introducing the treatment fluid and the spacer fluid intermittently into a subterranean formation comprising a fracture so as to alternate placement of the magnetic proppant particulates in the treatment fluid with the spacer fluid in the fracture, and activating the magnetic particles, wherein the activated magnetic particles cause the magnetic proppant particulates to agglomerate. Propping open the fracture with the magnetic proppant particulates, and activating the breaker in the spacer fluid so as to at least partially remove the spacer fluid from the fracture, thereby leaving behind substantially magnetic proppant particulate-free channels between the magnetic proppant particulates. |
