ABSTRACT:
A High-Rate Multizone Gravel Pack System is provided that allows significantly higher gravel packing flow rates than were previously available. This system includes a fluid bypass which greatly enhances flow rate and decreases damage to the bypass due to erosion. The system is employed in a multi-stage arrangement which allows the gravel-packing of multiple production zones with a single trip into the well bore. A memory gauge sensing wash pipe pressure and temperature is incorporated to allow for data acquisition during the gravel packing process.
