ABSTRACT:
The current invention provides methods for determining the sand production rate from unconsolidated and poorly consolidated subterranean formations under varying drawdown pressures. The current invention also allows for immediate production of fluid from the subterranean formation upon determination of the sand production rate. Additionally, the current invention provides a method for determining the detrimental sand production rate and/or the maximum sand free production rate for a subterranean formation. Finally, the current invention is applicable in vertical, horizontal, deviated and multi-lateral boreholes.
