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.
Claims17
An electrically conductive proppant particle, comprising:
- a sintered, substantially round and spherical particle having less than about 30% crush at 4,000 psi and a specific gravity of about 4 g/cm3 or less;
- and
- a non-uniform coating of an electrically conductive material having a thickness of at least about 10 nm formed on an outer surface of the 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.
