Abstract: 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.

Abstract: A method can include selecting a ratio of a first effective cross-sectional area of a first component of a gas lift valve to a second effective cross-sectional area of a second component of the gas lift valve; charging a chamber of the gas lift valve; and positioning the gas lift valve in a pocket to expose the gas lift valve to a tubing pressure and a casing pressure, where transitioning of the gas lift valve from a closed state to an open state depends at least in part on the selected ratio. Various other apparatuses, systems, methods, etc., are also disclosed.
