Abstract
A sidepocket gas lift mandrel assembly for installation in coiled tubing for providing gas lift to oil and gas wells is disclosed. The mandrel assembly includes inwardly projecting members offset from the centerline of the internal diameter of the housing which is adapted to receive wireline retrievable valves and latches. The gas lift mandrel housing is adapted to be connected to coiled tubing and may be of various geometric configurations for allowing the gas lift mandrel to be run into the well with coiled tubing. Conventional kickover tools are modified to include helical grooves that engage inwardly projecting camming and orienting surfaces of the mandrel assembly to orient, position and stabilize the tools while installing or retrieving wireline retrievable valve and latch assemblies.
