... to optimize wells such as average "hydraulic" fracture half-length, propped fracture half-length and conductivity for multi-clustered fracture stages. Ideally, well performance should be obtained from lookbacks instead of pounds per lateral length of the horizontal well (i.e. 2,400 lb. /ft.) or fixed volume...
