ELECTROSTATIC PARTICULATE COATING METHODS AND APPARATUS FOR FRACTURING FLUIDS

摘要

Disclosed is a method and apparatus for making up fracturing fluid with coated proppant. The apparatus applies opposed electrical charges to the proppant and its coating to create a uniform coating without extensive mechanical mixing, and additionally, the apparatus applies opposed electrical charges to the coated proppant and fracturing fluid to enhance mixing.

主权项

1. An apparatus for use in coating proppant material with proppant coating fluid for mixing with fracturing fluid, comprising:
a housing forming a chamber that is open at the top and bottom and unobstructed to allow proppant fed to the top opening to drop there through the housing and out the bottom opening; an electrically-charged plate mounted in the housing chamber; and a proppant coating fluid nozzle, located below the charged plate and having an opposite electrical charge.
