For producing wells with long and/or multiple reservoir/wellbore interfaces, monitoring of their inflow profile is an important input for being able to optimise the performance of the wells and reservoirs. This is particularly true in the case of unwanted fluid breakthroughs. Inflow profile monitoring can be obtained by running time lapse production logs or by installing permanent in-well sensors. These two techniques may however prove to be unfeasible, expensive and/or risky in some situations (wells equipped with down-hole pumps and/or two stage completions, subsea and/or highly deviated wells). Inflow profile monitoring can also be obtained through tracer based techniques. Compared to the other two techniques, these qualitative alternative techniques offer benefits in terms of installation flexibility, cost, and safety. During this session, service providers and operating companies will share their experience on the design, installation, data acquisition, and interpretation aspects of implementing these tracer based techniques. They will also describe how the obtained information is later applied as input for optimising the performance of the wells and reservoirs.
