Abstract
The present disclosure provides methods for identifying chemical diverter material placed in a borehole region and provides chemical diverter material. In one embodiment, a method for detecting diverter material placed in a borehole region includes (a) obtaining a first data set by: emitting pulses of neutrons from the pulsed neutron source into the borehole region and detecting capture gamma rays resulting from nuclear reactions in the borehole region; (b) placing a diverter material comprising aqueous-swellable particles and a thermal neutron absorbing material into the borehole region; (c) obtaining a second data set by: emitting pulses of neutrons from the first pulsed neutron source or a second pulsed neutron source into the borehole region, and detecting capture gamma rays in the borehole; and (d) comparing the first data set and the second data set to determine the location of diverter material placed in the borehole region.
