  • Tracer and method
    Patent number: 11136883
    Abstract: A tracer material for tracing fluid flows from a hydrocarbon reservoir. The tracer material is a particulate tracer material including a plurality of particles of a porous particulate solid material, the particles having pores containing a tracer composition characterised in that a retaining material overlies the tracer composition in at least some of the pores. The retaining material retards the release of the tracer material so that the tracer is released at a more constant rate over a longer period than in the absence of the retaining material.
    Type: Grant
    Filed: September 4, 2014
    Date of Patent: October 5, 2021
    Assignee: Johnson Matthey Public Limited Company
