Proppant intensity may increase by 35% in Permian Basin before reaching optimal economics

To maximize well productivity in the current low oil-price environment, operators in North America have adjusted their completion designs and substantially increased their proppant use. At $50 oil prices, that trend is expected to continue – particularly in the Permian, where our analysis indicates that proppant intensity will rise by 35% before reaching optimal economics. The resulting increase in North American demand – up from 45 million tons in 2016 to 110 million tons in 2018 – will be a boon for suppliers and a key driver of low-cost sand flooding into the Permian...

Comparison of Haynesville wells shows benefits of tighter cluster spacing, higher proppant loads

Techniques for optimized completions shown to result in higher EURs, flattened decline curves By Kelli Ainsworth Robinson, Associate Editor Optimized completion techniques – including longer laterals, tighter cluster spacing, and higher proppant loads and stage counts – can significantly increase the number of conductive transverse fractures and the estimated ultimate recovery (EUR) of Haynesville wells. The finding was made by Halliburton and Dallas-based E&P company Covey Park Energy in a study comparing two Haynesville wells – one completed in 2010 and one in 2016. Additionally, the study found that modern completion techniques can flatten the decline curve in Haynesville wells. The evolution of completion designs in the Haynesville have been driven, in large part, by the play’s low reservoir permeability, ...

Critical issues in drilling & completions

In North America, drilling contractors have become so good at what they do that it seems remaining improvements can only be incremental – measured in hours, minutes or even seconds. So where can companies look for the next step-change, the next differentiator that will set them apart from the competition? The consensus: automation and digitalization...
