Determining Sand Pack Size |
The size of the sand placed around the screen influences the amount of water that can be withdrawn from the well, particularly if the well is a pumping well. If the sand in the sand pack is too small, friction will be large, and the pumping capacity of the well will be decreased. Also, the fine sand may enter the well screen causing sand problems.
