Recorded on June 12, 2023 and May 25, 2023 Episode 86 of the PetroNerds podcast is part one of an incredible two part special with Liberty Energy's Director of R&D, Roy Aune. Trisha Curtis sits down with Roy at Liberty's office to discuss the state of the frac market and the evolution of frac, the role of natural gas, Tier 2, Tier 4, Dual Fuel for Tier 2 and Tier 4, and the electric frac fleet. Roy talks about the trends of the market and where Liberty is going, the move towards 100 percent natural gas and the Digi frac suite of technologies. This move is about emissions, but it is also about cost. Trisha and Roy discuss the impetus behind electric frac and what drove Liberty's pursuit. They get into field gas and the lessons of field gas. They talk about the white paper Liberty Energy put out "The Next Generation of Fracturing Fleets, A Liberty ESG Evaluation," the Btu requirements for gas, critical aspects of the supply chain and management of logistics, the benefits of Dual Fuel and the differences between Tier 2, Tier 4, and Dual Fuel engines and what the market is currently made up of. This conversation explains the EPA standards, engine and maintenance costs, and the the pros and cons of each set up. The first part of this two part special closes with what an electric frac fleet actually is, how it is powered by natural gas, how it works, and what the electricity requirements are and why gas works well to generate that electricity. This is a must listen to podcast for everyone in and outside of the oil and gas industry. https://www.libertyenergy.com/technical-papers/the-next-generation-of-fracturing-fleets-a-liberty-esg-evaluation/ https://youtu.be/24mxsHDmb_s
