Wireless activatable valve assembly
First Claim
1. A well screen assembly for use downhole comprising:
- a first fluid pathway configured to provide fluid communication between an exterior of a wellbore tubular and an interior of the wellbore tubular;
a flow restrictor disposed in the fluid pathway;
a first actuation system comprising a first receiving antenna, wherein the first receiving antenna is configured to generate an electric current in response to receiving a first electromagnetic signal having a first frequency; and
a first sliding member disposed in series with the flow restrictor in the fluid pathway, wherein the sliding member is transitional from a first position to a second position in response to the electric current;
wherein the sliding member prevents fluid communication along the fluid pathway when the sliding member is in the first position, and wherein the sliding member allows fluid communication along the fluid pathway when the sliding member is in the second position.

Abstract
A wireless actuation system comprises a transmitter, an actuation system comprising a receiving antenna, and one or more sliding members transitional from a first position to a second position. The transmitter is configured to transmit an electromagnetic signal, and the sliding member prevents a route of fluid communication via one or more ports of a housing when the sliding member is in the first position. The sliding member allows fluid communication via the one or more ports of the housing when the sliding member is in the second position, and the actuation system is configured to allow the sliding member to transition from the first position to the second position in response to recognition of the electromagnetic signal by the receiving antenna.

15. A method comprising:
-
preventing, by a first sliding member, fluid flow through a first fluid pathway in a well screen assembly, wherein the first fluid pathway is configured to provide fluid communication between an exterior of a wellbore tubular and an interior of the wellbore tubular; inductively coupling, by a first receiving antenna, with a first transmitting antenna that is transmitting a first signal; generating a first electric current in the first receiving antenna in response to receiving the first signal; translating the first sliding member using the first electric current; and allowing fluid flow through a flow restrictor is disposed in the first fluid pathway in response to the translating of the first sliding member. - View Dependent Claims (16, 17, 18)
