Reservoir Water Detection: ESMAN Tracers Identify Location Of Water Break-Thru

RESMAN has developed Intelligent Tracers that are deployed in the completion across the reservoir interval. These tracers provide insight into the location of water break-through. They lie dormant until activated by water produced from the reservoir at which time they release their unique chemical fingerprint (tracer). Samples of the produced water are analyzed and the concentration of the tracers provide insight to where water production has initiated along the reservoir interval.

In this application, the tracer was formed into long strands known as ‘filaments' and inserted into the premium screen between the outer shroud and the mesh layer. Some premium screen designs support this installation approach due to the space between the shroud and the mesh. The tracer can be deployed in a variety of forms to accommodate almost all screen types. Special designed carriers are utilized in situations where integration into existing completion components is not practical.
