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 16):
The method according to  claim 11 , the chemical injection line comprising a check valve disposed between the surface treatment fluid pump and the first injection port and the second injection port; and\n a density barrier fluidically positioned between the check valve and the first injection port and the second injection port, the density barrier having an axial loop and a circumferential loop relative to the production tubing string, thereby restricting migration of production fluid from the first injection port and the second injection port to the check valve regardless of the directional orientation of the well.
