Experimental and numerical investigation into nano-stabilized foams in low permeability reservoir hydraulic fracturing applications

Hydraulic fracturing is one of the most effective and efficient methods to enhance oil and gas recovery from reservoirs. Well productivity is mainly determined by the propped dimensions of the fracture. However, the propped dimensions are controlled by proppant transport and proppant placement, of which settling and convection are the controlling mechanisms. In this paper, a new concept is described to overcome the problem of proppant settling...
