Artificial lift well apparatus
An artificial lift apparatus for use in a high volume well is described. The apparatus is particularly suitable for gas injection through a tubing string into a surrounding casing string through which fluids are to be produced at high volumes. The apparatus consists of an inner tubular member having means for connecting it in the tubing string and an outer tubular member creating an annular passageway, each end of the passageway being in fluid communication with the inner tubular member and tubing string. The inner tubular member also may be provided with latch recesses in which the well tool may be latched. The well tool is adapted for movement through the tubing string into engagement with the latch recesses of the inner tubular member of the receiver. The well tool carries at least one valve for controlling fluid communication between the tubing string and surrounding casing string through ports provided in the receiver. (23 claims)
