Passive Reservoir Monitoring by Use of Inter-well Tracers
Recorded On: 09/19/2018
The use of tracers to monitor transport processes is a generic and versatile technique with a range of applications. In the subsurface domain, inter-well tracer testing has been used in more than 1000 injectors to monitor water and gas flooding worldwide the last 2-3 decades and has been used to map well-to-well communication and sweep and as a means to improve reservoir understanding. Recent tracer technology development, including new interpretation methodologies and access to a wide range of new tracers, has further strengthened this application of tracers. In this presentation, the status of tracer technology will be briefly reviewed. Recent improvements, including partitioning tracers will also be presented. Case studies that apply these methodologies will be highlighted. Operational challenges and pitfalls to avoid will also be discussed, as well as measures to be taken to assure reliability of the results.

VP Technology & Interpretation, Restrack
Dr. Huseby holds a PhD in Reservoir Physics from the University of Oslo (Norway). After PhD and Post-Doc studies in Poitiers and Paris on transport processes in discrete fracture networks, Olaf has 17 years’ research and consultancy experience in reservoir and tracer studies, including inter-well gas and water tracers, partitioning inter well tracers to assess oil saturation and single well tracer testing. He co-developed Restrack's interpretation schemes for inter-well and single well tracer data, including simulation as well as analytical techniques. He has published more than 40 scientific papers, and co-chaired and co-organized several SPE workshops, including SPE's 2014 and 2016 workshops on tracer technology that took place in Dubai and Kuwait respectively; and was co-chair of SPE tracer technology workshop that was held in March 2018 in Abu Dhabi.
