EVOLVE On-Demand: Beyond Tier 1: Value Creation Through Innovation and Expansion

Wednesday, June 24, 2026
12:00 AM | Central Time

Webinar details

Tier 1 shale inventory is shrinking. For operators, that means the game is changing: the assets that remain require smarter development strategies, tighter capital discipline, and a willingness to innovate where others have walked away. 

Watch this on-demand session featuring the CEO of Grayson Mill Energybpx Energy’s head of Eagle Ford development, and a leading E&P investor to get the full picture on how operators are squeezing Tier 1-level economics out of Tier 2 and Tier 3 rock. 

What you’ll learn: 

  • Why most E&P companies struggle to create value, and what separates the ones that consistently compound returns 
  • How long laterals, infrastructure investment, and incremental operational improvements can transform uneconomic assets into viable ones 
  • What BPX Energy’s late-life redevelopment playbook in the Eagle Ford looks like in practice, from infill drilling to EOR 
  • How commodity prices are reshaping the definition of “Tier 1” and what that means for capital allocation decisions 
  • Why private equity’s role in the sector is evolving toward vertical integration and creative financing
