Abstract
Gas and liquid velocities of fluid in a lift gas assisted well system are estimated by adding liquid and gas tracers downhole and monitoring their travel time over a known distance. Based on estimated velocities, a slip factor is obtained that represents relative velocities of the gas and liquid in the fluid. A flow regime of the fluid is identified based on the slip factor. The flow regime is optionally altered by adjusting one or more operational parameters of the well.
