A sidepocket mandrel for use in a well tubing having coaxial threaded connections about an end bore at each end for connection in a well tubing. The body includes a main portion having an open bore and a flow control device receiving pocket offset from the open bore. The longitudinal axis of the open bore is offset from the axis of the end bores. The body includes a space portion both above and below the main body portion for allowing the passage of a well tool of a predetermined length and size which could not pass directly between an end bore and the open bore. The space portions have a bore greater in lateral drift dimension than the open bore and have a length greater than the predetermined length of the well tool whereby the well tool may move laterally in the space portions for alignment with either an end bore or the open bore.
