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.

Petroleum Production Optimization

SAND CONTROL MANAGEMENT When oil is produced from relatively weak reservoir rocks, small particles and sand grains are dislodged and carried along with the flow. This sand production can create erosion in flowlines and other equipment. Sand management can be considered as a key issues in field development in most of world’s oil and gas fields.
