WellTracer® is a patented gas-lifted well diagnostic and surveillance technology originally developed by Shell. WellTracer® creates a snapshot of the well performance by introducing a small volume of CO2 into the injection line then measuring CO2 concentration at the well head. WellTracer® equipment is highly portable and requires simple surface wellhead connections to rig up with no well intervention and no production deferment. Most operators have realized as much as 5% to 35% increased production as a result of using WellTracer®.
WellTracer® offers a low cost and effective method to determine lift gas entry points in the well quickly and reliably:
Detects operating lift depth
Detects multiple points of injection
Detects tubing leaks
Determines lift gas rate through each injection point
Determines allocation of lift gas to each string of a dual completrion well
Prove operation and uncover problems without risky intervention or loss of production using the patented WellTracer service
Increase production using GLUE, our workgroup surveillance software. Receive a GLUE well model, detailed reports, and expert recommendations with WellTracer surveys. Make use of well history, measured, and real time data to realize gains and save resources and time.
The WellTracer equipment is man-portable and only requires two temporary connection points: one on the gas injection line and one on the production line. WellTracer® will remain connected for the duration of the trace.
WellTracer® uses patented technology to inject liquid CO2.
