Abstract
Electrically conductive proppant particles having non-uniform electrically conductive coatings are disclosed. The non-uniform electrically conductive coatings can have a thickness of at least about 10 nm formed on an outer surface of a sintered, substantially round and spherical particle, wherein less than 95% of the outer surface of the sintered, substantially round and spherical particle is coated with the electrically conductive material. Methods for making and using such electrically conductive proppant particles having non-uniform electrically conductive coatings are also disclosed.
