Abstract
A launch point lift gas velocity control system and method of use, the system operating to maintain minimal well bore lift conditions through injection gas regulation. In one aspect, the minimal wellbore conditions enable a gas-liquid mixture or a downhole tool at a selectable well bore launch point to depart from a targeted launch point lift gas velocity and ascend up the well bore. The launch point may be adjusted to account for variability with time and wellbore location.
