ABSTRACT:
A method is disclosed for insuring oil well treatment as with a corrosion inhibitor, for example, with a precise slug of a chemical on a regular basis comprising, briefly, repeatedly and precisely ejecting precisely spaced apart consecutive predetermined slugs of a chemical to the oil well by operating a first valve responsive to a first timer, and repeatedly and precisely ejecting a predetermined precise slug of a flush liquid behind each chemical slug by operating a second valve responsive to a second timer for insuring oil well chemical treatment on a regular basis as scheduled and for eliminating personnel time required for manually flushing each chemical slug throughout the oil well for an extended period of time.
