Abstract

See full text

An electrically actuated downhole system for controlling and monitoring the flow of gas from a gas lift petroleum well in which a borehole penetrates at least two spacially separated geological production zones, and at least two strings of parallel tubing extend along the interior of a well casing, each string being associated with a separate production zone. Connected to each string is a gas lift valve associated with the string's respective spacially separated production zone. A single source of pressurized gas is connected to the casing at the wellhead to provide a source of lift gas. A control unit located at the surface independently controls and monitors the size of the flow control aperture of each gas lift valve to control the production of fluids from each separate production zone. Control cables carry readings from downhole pressure and flow-rate sensors to the control unit, and in response, carry control signals back to each gas lift valve to control its aperture size.
