ABSTRACT:
A sand slurry injection system and/or method can include mixing a drilling mud inhibitor with water to form a water mixture; mixing the water mixture with sand to form a sand slurry; and injecting the sand slurry into an unstable ground subsurface area to stabilize the area. The water mixture can be pumped under pressure into the bottom and/or into the middle of the hopper to help maintain the sand slurry in suspension. The water mixture can be pumped into two opposed injection ports at each of the bottom and the middle of the hopper. The two upper injection ports can be oriented at a 90 degree angle from the two bottom injection ports.
