crushed rock challenges

Publication Detail

Crushed-Rock Analysis Workflow Based on Advanced Fluid Chara. Sustained E&P activity levels and slim margins on highly valued Permian Basin acreage drive operators to leverage information as much as possible and in ways not seen in the recent past. Data accuracy, especially in this fast-paced, competitive environment, is strongly desired.
