A Masterclass from John Ely, who received the ‘Legend of Hydraulic Fracturing’ award in 2021! John builds a case for a different technique to enable economic completion of tight reservoirs. This overcomes the tendency to "pump more sand" and the long-held concerns of destroying near-well permeability. Learnings from the Bossier Shale production enhancement, a unique Slickwater technique to stimulate verticals in ultra-tight reservoirs, help us optimize present-day horizontal designs. This leads to large volumes with much less proppant, and very selective perforating. Multiple well production data from 7 different reservoirs, and a comparison of production and economics with the "Waterfrac Sweep" process and offset horizontal production is presented. We go in-depth with a particular play in New Mexico.
