Abstract: A system for chemical treatment of producing hydrocarbon wells and other equipment. In one example arrangement, a number of treatment fluids are stored in treatment fluid reservoirs, and a number of carrier fluids are stored in carrier fluid reservoirs. Each reservoir has an associated valve, such that the fluids can be selectively drawn from the reservoirs and pumped to a treatment target. The treatment fluid reservoirs may be connected to a treatment fluid manifold, and the carrier fluid reservoirs may be connected to a carrier fluid manifold. Fluids drawn from the reservoirs may be directed to a distribution manifold and delivered to specific treatment targets using valves on outlets of the distribution manifold.
