FlowTrace

FlowTrace (patented) provides rate at the location where it is installed. FlowTrace located at some depths along the will therefore provide data similar to a production log. This is achieved by a patented technology where tracer rods are placed in special designed carriers. It requires a shut-in to accumulate a high concentrated tracer cloud inside the carriers. These clouds are swept into the wellbore where the time needed is correlated with the flow.

FlowTrace is designed to overcome the problem caused by internal cross-flow during shut-in. For FlowTrace the tracer cloud is shielded from cross-flow and the result can be trusted also in these cases.
