At its most basic, a chemical tracer allows operators to see the flow-back from each stage of Shale production 's growing complexity requires more evolved chemical tests to provide correlations between the stage production of oil and the geophysical data of a well . While only 15 tracers per well were used to identify how operational efficiency could be improved five years ago , now wells more commonly use 50 tracers , said Dave Smith , Tracerco 's Reservoir business development manager . Oil and gas diagnostics : Tracerco seeks to develop more environmentally friendly chemical tests that work for different types of well .
