Methods including deactivation and activation of permeability modifiers for use in subterranean formation operations. A first treatment fluid may be introduced into a subterranean formation having a first treatment zone having a first aqueous permeability value, the first treatment fluid comprising a first aqueous base fluid and a deactivated permeability modifier. The deactivated permeability modifier may be adsorbed onto a surface of the first treatment zone. A second treatment may thereafter be introduced into the subterranean formation, the second treatment fluid comprising a second aqueous base fluid and a cyclodextrin compound. The second treatment fluid may contact the deactivated permeability modifier to activate the permeability modifier by complexing the deactivating surfactant with the cyclodextrin compound, thereby forming an activated permeability modifier adsorbed onto the surface of the first treatment zone and reducing the aqueous permeability of the first treatment zone.

A method of fracturing a subterranean formation comprises introducing into the formation at a pressure sufficient to create or enlarge a fracture in the formation a fracturing composition comprising a carrier and a substantially spherical polymeric particulate derived from a cashew nut shell liquid, the substantially spherical polymeric particulate having an apparent specific gravity of less than about 2.4.

The invention relates to a propped, fractured, subterranean field with (a) a first proppant and (b) a second proppant that exhibits a relatively higher average crush strength and/or an ability to form a particle to particle bonded structure than the first proppant. Preferably, the first proppant is uncoated sand and the second proppant is resin-coated sand. The proppants can be deposited as a substantially homogeneous mixture or in layered structures (vertical or horizontal) within the fractured field. Deformation of the second proppant under closure stress acts to spread out the compression pressures in a mixture so as to reduce failure of the first proppant. Similar protective effects are found when the proppants are deposited in layers. When formed as vertical pillar structures, the second proppant structures can also act as in-situ screens that inhibit formation fines from migrating through the proppant pack to the detriment of field conductivity.

A system for mapping a fracture comprising: a fracture located within a subterranean formation; a proppant pack located within the fracture, wherein at least a portion of the proppant are coated with a curable resin system comprising a curable resin and an electrically-conductive, nano-sized material, and wherein the coated proppant is electrically conductive; a transmitter that sends an electrical signal into the proppant pack; and a receiver that receives the electrical signal from the proppant pack. A method of mapping at least a portion of a fracture comprising: introducing proppant into the fracture; coating at least a portion of the proppant with a curable resin system, wherein the curable resin system comprises: a curable resin; and an electrically-conductive, nano-sized material, wherein at least the portion of the proppant becomes electrically-conductive after the step of coating; and using the electrically-conductive proppant to map at least the portion of the fracture.
