Abstract: According to an aspect of the present invention, a stackable storage rack system suitable for storing containers is provided. The system includes a base. The system also includes a plurality of compartments positionable within the base, wherein the compartments form a cavity within the base and have an opening on a top of the base designed to store containers. The system further includes at least 4 legs, wherein a top of the legs are connected to a bottom of the base at four separate bottom corners of the base. Additionally, the system includes an operational space formed by stacking at least two storage racks one on top of another wherein users of the system can retrieve containers from the bottom storage rack without interference from the top storage rack.

Abstract: A method for producing hydrocarbons from a subterranean formation which reduces sand packing in a producing well completed in a zone adjacent the hydrocarbon-bearing formation. The method includes the steps of producing a fluid from the formation which contains both a hydrocarbon phase and an aqueous phase, and simultaneously therewith, injecting a sand control agent, such as a quarternized acylated condensed alkanolamine, into the well adjacent the production zone at a rate to obtain a wellhead concentration of the agent in the aqueous phase in the produced fluid effective to flocculate the concomitantly produced sand particles. The sand particles so treated have a reduced tendency to pack in the well bore and are safely produced with the formation fluids. The method may be practiced in conjunction with conventional sand control techniques, or may be employed as the sole means of sand control.
