Boosting well production to maximum sand-free rate

At 11:35, the choke is opened to 40% and once again, the well begins to produce sand. Opening the the choke gives the well a "kick," and this can be seen clearly in the sand production curve. Sand production continues to increase and probably comes from the reservoir itself. This sandstorm lasts from around 14:30 to 15:20.

Sand Management System - Forum Energy Technologies, Inc

Many sand control completions use sand screens to filter solids at the end of the production strings. Variable grain sizes within a reservoir mean that even a carefully selected screen can only partially filter most of the grains. Sand screens quickly plug and erode, requiring lengthy sections downhole to ensure adequate performance.
