Abstract
A composite proppant having an increased buoyancy comprising a proppant substrate such as a porous ceramic or a silica sand coated with a material of a lesser actual density than the apparent density of the proppant substrate to increase the buoyancy of the composite proppant.
Claims18
A method for treating a subterranean formation comprising introducing into fractures in the formation particles comprising a composite proppant, said composite proppant comprising a core of a proppant substrate having an adhered coating of a particulate material, the particulate material having an actual density less than an apparent density of the proppant substrate.
A particulate composite proppant comprising a proppant substrate capable of withstanding a closure pressure of at least about 5,000 psi and having an adhered coating of a particulate material with an actual density less than an apparent density of the proppant substrate.
