Existing fracture characterization methods (eg, microseismic) detect fractures created during
hydraulic fracturing, but cannot determine whether the fractures are propped or not. The goal …

Microseismic data collected during hydraulic fracturing of shales indicates the position of the
fractures created, but not the fractures propped and connected to the well. The goal of this …

Tracer eluting proppants, such as proppants that have polymeric coatings on them that
include tracers, such as a fluorescent dye. The tracer eluting proppants can comprise …

A tool using downhole electrical measurements for mapping electrically conductive proppant
in hydraulic fractures is presented. The method relies on direct excitation of the casing …
