GRAVEL PACK APPARATUS HAVING ACTUATED VALVES

摘要

A gravel pack apparatus has a valve and port system for controlling fluid flow therethrough. The apparatus has a tool defining ports for fluidly communicating with a screen assembly and an outlet, vavles for controlling fluid flow through the tool, a signal receiver and an actuator for operating the valves in response to the signal receiver. In an embodiment, an apparatus and method allows a bore valve in a washpipe of a crossover tool and in certain instances a port valve or sliding sleeve to open or close upon command from the surface so that gravel slurry may be placed in a wellbore around a wellscreen.
