Abstract

A petroleum well (20) comprises a well casing (30), a production tubing (40), a source of time-varying current (68), a downhole chemical injection device (60), and a downhole induction choke (90). The casing (30) extends within a wellbore of the well (20). The tubing (40) extends within the casing (30). The current source (68) is located at the surface. The current source (68) is electrically connected to, and adapted to output a time-varying current into, the tubing (40) and/or the casing (30), which act as electrical conductors for providing downhole power and/or communications. The injection device (60) comprises a communications and control module (80), a chemical container (82), and an electrically controllable chemical injector (84). The communications and control module (80) is electrically connected to the tubing (40) and/or the casing (30). The chemical injector (84) is electrically connected to the communications and control module (80), and is in fluid communication with the chemical container (82). The downhole induction choke (90) is located about a portion of the tubing (40) and/or the casing (30). The induction choke (90) is adapted to route part of the electrical current through the communications and control module (80) by creating a voltage potential between one side of the induction choke (90) and another side of the induction choke (90). The communications and control module (80) is electrically connected across the voltage potential. Also, a method is provided for controllably injecting a chemical into the well (20) downhole, which may be used to: improve lift efficiency with a foaming agent, prevent deposition of solids with a paraffin solvent, improve a flow characteristic of the flow stream with a surfactant, prevent corrosion with a corrosion inhibitor, and/or prevent scaling with scale preventers.
