“We believe that the Barnett shale offers compelling evidence that technology improvements ultimately cannot overcome geology. We believe the implication is that shale is a scarcer resource than generally considered and thus are more constructive longer-term as the world must seek a more marginal barrel to match future demand growth. That is bullish for longer-term oil price.”
“Increasing lateral length hurts all horizontal well performance as frictional losses increase and in the Barnett, optimal well length was determined by balancing reduction of fixed costs with reduced incremental production. Even correcting for lateral length, Barnett wells got worse with time. The E&P narrative is that a revolution in technology of improved completions (more sand, water, clusters, geo-steering, landing, etc.) is pushing down the cost curve. Yet we fail to see it in the most complete data record we have.”
