| Abstract: Placement of proppant in subterranean formations during hydraulic
fracturing is assessed. A method of one aspect includes introducing a
hydraulic fracturing fluid including a proppant into a subterranean
formation through a well. Samples of the hydraulic fracturing fluid are
recovered through the well over a period of time. A concentration of at
least one tracer in each of the samples is determined. The concentrations
of the at least one tracer in the samples are analyzed to assess
placement of the proppant in the subterranean formation. Other methods,
apparatus, and systems are also disclosed. |
