The smart tracers will enable fluid inflow measurement of both heavy oil and water in various zones within the long horizontal wells.
The Tracer Production Log can be deployed without interruption to well production and allows operators to improve understanding of their production inflow, the company adds, by monitoring both the oil and water phases at a fraction of the cost of a traditional production logging technology.
Statoil was said to be swayed by the flexibility of tracer integration into the specified screen design and the tracer lifetime performance, which can extend to several years.
Nils Gunnar Sætherø, Mariner Petroleum Technology manager, said: “We see the use of chemical tracers as a key technology for the verification of well clean-up as well as improved well productivity understanding. We believe the use of chemical tracers gives the optimum cost benefit to the Mariner project in the current economic climate...”
The deployment is due to start next spring, initially to measure clean-out efficiency initially, with further measurements provided into the life of the wells.
