ABSTRACT:
A column of high density well treatment composition in liquid or solid form is stored in the bottom portion of the well bore of a producing fluid well and is subjected to fluid pressure from the well fluid. The flow of production fluid is used to create a pressure differential between the treatment composition and a treatment fluid injection outlet, thereby causing the treatment fluid to flow through the injection outlet. By locating the outlet in the flow of production fluid, the resulting flowing pressure drop creates the necessary differential pressure. The rate of flow of treatment fluid is metered by a capillary tube at the outlet or by a flow-actuated positive displacement pump. In all but one of the embodiments, the inlet of the conduit is at the bottom of a column of treatment liquid and at the top of a column of treatment solids. In another embodiment formation, fluid percolates up through a bed of solid treatment particles and into the well bore.
