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.
