A method of forming a propped fracture comprising: providing a fracture havi ng a far-well bore area and a near-well bore area; placing first proppant particulates at least partially coated with an adhesive substance; placing a portion of second proppant particulates in the near-well bore area of the fracture so as to form a high porosity propped region in the near-well bore. A method of stimulating a producing interval comprising: hydraulically fracturing to create a fracture having a far-well bore area and a near-well bore area; placing a portion of first proppant particulates at least partially coated with an adhesive substance in the far - well bore area of the fracture; and, placing a portion of second proppant particulates in the near - well bore area of the fracture to form a high porosity propped region in the near-well bore area.< /SDOAB>
