Tracer technology can be used to probe reservoirs by conveying chemicals of various types with the injected fluids. Detection of tracers at the producers can prove well-to-well fluid communication in the case of interwell tracers, and tracer production curves helps to derive reservoir characteristics along the flow path. This session will focus on how tracers can be used in order to enhance the knowledge of the reservoir characteristics. It will include case studies demonstrating that this improved understanding can be transformed into value and impact the reservoir development.
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.
Tracers are an essential component for successful EOR implementation. Tracers can be used in all stages of the EOR process from conception, pilots, and field implementation to improve decision making and ultimately reduce the risk associated with EOR. Tracers can identify EOR target oil, quantify EOR effectiveness, and identify flow paths. Tracer data should be used to balance flow fields and update simulation models, ultimately improving upon the ability of the producer to successfully advance their EOR projects. This session will touch upon tracer technologies applied to EOR and the insight that may be gained from tracer technology implementation in EOR projects.

The goal of this session is to discuss the challenges and opportunities of the tracer technology in thermal recovery and unconventional resources. Commercial thermal recovery projects are relatively new within the oil and gas industry, so there is limited data, by another hand, unconventional development has shifted from dry gas to multi-phase liquid flow, 10,000 ft. is the new standard for lateral length, completions designs, are five times more intense than five years ago, and oil is half the price. Because of this, is considerable value in sharing knowledge and ideas to help overcome these challenges with tracers.

Smart tracers are developed and used to provide information about reservoirs and wells including the DNA and smart tracers where operators gain insight into the effectiveness of fracture design and production profile. This session will cover the new and ongoing innovation in tracers and their applications in conventional and unconventional reservoirs to provide information to further optimise the production. This session is also open to presentations on new modelling and interpretation techniques to analyse tracer data.
The main objective of the session is to highlight the latest development of tracer technologies for conventional and unconventional resources and highlight the challenges encountered.
