Sand control crossover tool with mud pulse telemetry position

摘要

A completion tool for gravel packing screens incorporates an added position to allow redirection of flow to a signal transmission tool at the needed flow rates to optimize signal to noise ratios by creation of a discrete flow path that channels the desired flow directly to the device and using the production tubing and upper annulus as the balance of the flow circuit. The Smart Collet® has a landing location for this position which is preferably between the circulation and reverse positions of the crossover tool. The wash pipe assembly can have a shifting tool that closes the sleeve over the gravel exit ports for the information transmittal such ports can thereafter remain closed because the gravel packing is complete but for the reversing out of excess gravel which happens above the gravel exit ports.
