A coiled tubing gas injection mandrel includes a housing assembly capable of attachment to coiled tubing, wherein the housing assembly comprises an up-hole end, a down-hole end, a sleeve longitudinally integrally connected with the up-hole end and the down-hole end, and a slide-through valve receptacle assembly removably connected within the sleeve. In more detail, the slide-through valve receptacle assembly comprises an up-hole pipe with a shoulder, at least one laterally extending projection, at least one laterally extending port, a down-hole pipe integrally connected with the up-hole pipe, and a longitudinal bore within the up-hole pipe and down-hole pipe. The up-hole end and down-hole end are capable of attachment with coiled tubing. The slide-through valve assembly and the sleeve form a gas flow passageway, wherein the gas flow passageway controls the flow of gas through a gas lift valve installed in the slide-through valve receptacle for gas being injected into the coiled tubing.
