decremented operating presssures resulting in the inability to make use of full available lift pressure therefore resulting in further inefficiency referring more specifically to fig4 a and 4b a more detailed illustration of controllable gas lift valve 52 and side pocket mandrel 54 is provided side pocket mandrel 54 includes a housing 68 having a gas inlet port 72 and a gas outlet port 74 when controllable valve 52 is in an open position gas inlet port 72 and gas outlet port 74 provide fluid communication between annular space 31 and an interior of tubing string 26 in a closed position controllable valve 52 prevents fluid communication between annular space 31 and the interior of tubing string 26 in a plurality of intermediate positions located between the open and closed positions controllable valve 52 meters the amount of gas flowing from annular space 31 into tubing string 26 through gas inlet port 72 and gas outlet port 74 controllable gas lift valve 52 includes a generally cylindrical hollow housing 80 configured for reception in side pocket mandrel 54 and is furnished with a latching method to leave and retrieve the valve using a tubing accessible method such as slickline an electronics module 82 is disposed within housing 80 and is electrically connected to a stepper motor 34 for controlling the operation thereof operation of stepper motor 84 adjusts a needle valve head 86 thereby controlling the position of needle valve.
