System To Efficiently Deliver High Pour Point Chemicals To Oil Well Formations

摘要

A solid chemical delivery system for delivering chemicals to an underground formation. The solid chemical is formed by dehydrating amorphous silica to form anhydrous silica. High pour point well chemicals are heated to reduce viscosity then introduced to the silica and form a tablet or pelletized chemical. The pelletized chemical is coated to further time-release the introduction of the chemical. The pelletized solid chemical may be delivered to the underground formation through the well bore with a proppant and fracturing fluid.

1. A method for delivering a well treatment chemical into a wellbore comprising:
providing a precipitated amorphous silica matrix; heating a high pour point well treatment chemical to reduce its viscosity; mixing the high pour point well treatment chemical with the precipitated amorphous silica matrix; cooling the high pour point well treatment chemical within the precipitated amorphous silica matrix to form a first solid treatment device; and providing the first solid treatment device to an underground formation.
