  • Hydraulic fracture optimization in unconventional reservoirs


    Pedro Saldungaray and Terry Palish

    A primary goal in unconventional reservoirs is to contact as much rock as possible with a fracture or a fracture network of appropriate conductivity. This objective is typically accomplished by drilling horizontal wells and placing multiple transverse fracs along the lateral. Reservoir contact is optimized by defining the lateral length, the number of stages to be placed in the lateral, the fracture isolation technique and job size. Fracture conductivity is determined by the proppant type and size, fracturing fluid system and placement technique. Fracture geometry optimization involves defining the desired fracture half-length, width and conductivity for maximized production.
