Abstract
A particle with an environmentally friendly resin coating having very low levels of leachable compounds is disclosed. The water leachable phenolic content of the coated particle is low enough to eliminate problems with leaching of phenol or its derivatives into an aquifer during downhole applications. Processes for fully and partially coating the particle with the resin coating are also disclosed.
