Un ensamble de mandril de válvula barrera de levantamiento por gas incluye un miembro tubular que se extiende longitudinalmente que define un conducto de producción y tiene un eje longitudinal central. Un mandril de bolsillo lateral que tiene un primer bolsillo para la aceptación de una válvula barrera de levantamiento por gas y tiene un primer eje central. El mandril de bolsillo lateral tiene un segundo bolsillo para aceptar una válvula barrera de levantamiento por gas y tiene un segundo eje central. El eje central del conducto de la producción, el primer eje y el segundo eje no son coaxiales y son paralelos entre sí. Un primer pasaje conecta de forma fluida con el exterior del mandril a un interior del primer bolsillo. Un segundo pasaje conecta en forma fluida el interior del primer bolsillo con el interior de un segundo bolsillo. Un tercer pasaje conecta en forma fluida el interior del segundo bolsillo con el conducto de producción. Un cuarto pasaje conecta el primer bolsillo con el conducto de producción y permite la inserción de una barrera de levantamiento por gas en el primer bolsillo. Un quinto pasaje conecta el segundo bolsillo con el conducto de producción y permite la inserción de una barrera de levantamiento por gas en el segundo bolsillo.A gas lift barrier valve mandrel assembly includes a longitudinally extending tubular member that defines a production conduit and has a central longitudinal axis. A side pocket mandrel that has a first pocket for acceptance of a gas lift barrier valve and has a first central axis. The side pocket mandrel has a second pocket to accept a gas lift barrier valve and has a second central axis. The central axis of the production duct, the first axis and the second axis are not coaxial and are parallel to each other. A first passage fluidly connects the exterior of the mandrel to an interior of the first pocket. A second passage fluidly connects the inside of the first pocket with the inside of a second pocket. A third passage fluidly connects the inside of the second pocket with the production duct. A fourth passage connects the first pocket with the production duct and allows the insertion of a gas lifting barrier in the first pocket. A fifth passage connects the second pocket with the production duct and allows the insertion of a gas lifting barrier in the second pocket.
