Sand production: A smart control framework for risk mitigation

Conventional-oil sand production has been classified on the basis of distinct reservoir evolution stages: The early transient sand-production period, when some of the perforation-induced damage has been removed and the cavities may have a zone of reduced permeability around them, leading to a steep exit gradient. A stable production period with ...

Numerical simulation on natural gas hydrates exploitation via

When the total branch length reaches 400 m, the cumulative sand production is 854.1 m 3, which is only 7 % higher than the 794.5 m 3 produced with a 300 m branch length. Notably, the increase in sand production is not linear, suggesting that within a certain length range, the impact of extending branch length on sand production diminishes.
