Abstract
An injection well control method and apparatus controls fluid injection rates during secondary or tertiary petroleum recovery operations by monitoring bottomhole pressure adjacent an underground formation receiving the injected fluids while simultaneously adjusting the fluid injection rate to substantially reduce unwanted variations in said bottomhole pressure. The injection controller is further adapted for operation on a solar-powered circuit to eliminate the need for electrical power lines in remote geographical locations.
