Abstract
A method and apparatus for selectively producing fluids from multiple lateral wellbores that extend from a central wellbore. The apparatus comprises a fluid flow assembly with a selectively openable and adjustable flow control valve in communication with a production tubing, located in the central wellbore between packers, and a lateral wellbore, and a selectively openable access door located adjacent the lateral wellbore allowing and preventing service tool entry into the lateral wellbore. The valve and door are individually controlled from the earth's surface.
Claims10
A flow control assembly comprising:
- a body having a central bore extending therethrough, and having means on one end thereof for interconnection to a well tubing;
- and
- a selectively operable lateral access door in the body for alternately permitting and preventing a service tool from laterally exiting the body therethrough, the lateral access door comprising a plug member having a beveled exterior surface adapted to move in relation to an interior surface of the body to either close or open a lateral access port in the body, and to guide a service tool out the lateral access port.
A lateral access assembly for interconnection to a well tubing, the well tubing being disposed in a central wellbore having at least one lateral wellbore extending therefrom, the lateral access assembly comprising:
- a body having a central bore extending therethrough;
- a communication conduit connecting a rotary motor disposed within the body to a surface control panel;
- and,
- a lateral access door disposed in the central bore, connected to the rotary motor, and having an open position to permit entry of a service tool into the lateral wellbore and a closed position to restrict entry of the service tool into the lateral wellbore;
- whereby power is transmitted through the communication conduit to the rotary motor to rotate the lateral access door to its closed and open positions.
