Claim:
1. An injection system operative to controllably inject an additive into a hydrocarbon production conduit, comprising: a pump fluidly connected to an additive source and a hydrocarbon production conduit, said pump being operative to inject additive from said additive source into said hydrocarbon production conduit; a flow meter disposed in a fluid conduit connecting said additive source and said hydrocarbon production conduit, said flow meter providing output signals representative of fluid volumes pumped by said pump during and after a pump cycle, wherein activation and deactivation of said pump defines the pump cycle; a controller operatively connected to said pump and said flow meter and configured to inject a total injection volume of the additive over an injection period and in a plurality of discrete pump cycles, said controller being further operative during each discrete pump cycle to:
