Abstract:
A downhole chemical injection system that may include at least a first and a second injection port. The first injection port may be fluidically coupled with a chemical injection line and fluidically coupled with a production tubing string to inject the chemical into the production tubing string. Similarly, the second injection port may be fluidically coupled with the chemical injection line and fluidically coupled with the production tubing string to inject the chemical into the production tubing string. The first injection port may include at least a first radially extending injection nozzle, extending injection nozzle extending in a first radial direction relative to a central axis of the production tubing string. Similarly, the second injection port may include at least a second radially extending injection nozzle, extending in a second radial direction relative to the central axis of the production tubing string.

Claim (Index 18):
A method for injecting a chemical into a production tubing string, the method comprising:\n fluidically coupling a downhole chemical injection system with a production tubing string and a surface treatment fluid pump via a chemical injection line, disposing the downhole chemical injection system in a well; pumping the chemical from the surface treatment pump through the chemical injection line; and injecting the chemical into the production tubing string via a plurality of injection nozzles, wherein for a given mass flow rate of the chemical from the surface treatment fluid pump, the average chemical volume fraction of the chemical injected into the production tubing string via the plurality of injection nozzles measured at about one foot downstream of the plurality of injection nozzles, is greater than a chemical volume fraction of the chemical measured at about one foot downstream of the single injection port that would be obtained by injecting the chemical into the production tubing string via only a single injection nozzle.
