Abstract
A production tubing is disposed in a wellbore. Hydrocarbons entrapped in a subterranean zone enter the wellbore. Multiple valves are disposed in the production tubing at respective multiple tubing locations. The multiple valves divide the production tubing into multiple stages. A presence of hydrocarbons in a first stage terminating at a first valve is determined and gas is injected into the first stage causing the hydrocarbons in the first stage to flow uphole through the first valve into a second stage uphole of the first stage. It is determined that the second stage is filled with the hydrocarbons and injection of the gas into the first stage is ceased. Multiple side chambers are disposed in the respective multiple stages. Determining the presence of hydrocarbons in the first stage incudes detecting a fluidic level of the hydrocarbons inside the first side chamber.
