Abstract
A method for determining the minimum length for a fracture in a fluid-producing formation to control the production of sand therefrom wherein a plurality of critical drawdown pressures are calculated from known formation data which correspond to a plurality of different, estimated respective fracture lengths. Once the critical drawdown pressures for the reservoir are correlated with their corresponding fracture lengths, a critical drawdown curve for that particular reservoir is established. Additional sets of curves are generated from known data which when overlaid with the critical drawdown pressure curve allows a minimum length of fracture to be selected which will produce the formation at a given rate at a prescribed drawdown pressure without producing any substantial amounts of sand from the formation.
