Abstract

Mapping propped fractures in a well can be performed using a mixture including a proppant and an encapsulated salt. The proppant can be positioned in a fracture in the well for propping open the fracture to form a propped fracture. The encapsulated salt can be positioned in the propped fracture proximate to the proppant and include a salt and a non-permeable coating. The salt can be dissolved in response to fracture closure, encapsulant degradation, or encapsulant dissolution to form an electrically conductive solution usable for mapping the propped fracture. The non-permeable coating can prevent a fluid from contacting the salt during pumping and placement operations.
