ABSTRACT:
A liquid chemical, such as a corrosion inhibitor, is inserted into a producing well by pouring the chemical into an elongate carrier and then dropping the carrier into the well. The liquid chemical and the carrier are selected so that the carrier is dissolved by the chemical. The chemical is therefore delivered into the well toward the bottom thereof where it is desired to place the chemical.
