Abstract: The present disclosure provides a blender apparatus that can be used to prepare a slurry from carrier fluids and solids. In a preferred embodiment, the blender includes a mixing tub system, a fluids intake system, a solids intake system and a slurry delivery system. The fluids intake system preferably includes a first intake pump and a second intake pump that independently or cooperatively draw fluids into the blender. The slurry delivery system preferably includes a first discharge pump and a second discharge pump that independently or cooperatively delivery slurry from the mixing tub system.

Abstract: A centralizer for engagement with a pipe exterior surface to be positioned downhole in a wellbore. The centralizer includes a collar which can be fastened with set screws or other connector to the pipe exterior surface. A body is engaged with said collar for containing axial movement of the body within a selected portion of the pipe exterior surface while facilitating rotational movement of the body relative to the pipe exterior surface. The engagement between the collar and the body permits rigid attachment of the collar to the pipe while permitting the centralizer to free-float relative to the pipe.
