Abstract:
A chemical injection mandrel for injecting chemicals into a Lower Tertiary well includes a chemical injector disposed on an exterior surface of a mandrel. The chemical injection mandrel connects to the production tubing such that the chemical injector portion of the chemical injection mandrel is disposed in the annulus between the production tubing and wellbore at or near the bottom of the hole. A floating production storage and offloading unit on the surface of the water may include a chemical injection pump that injects chemicals downhole via a chemical fluid line that runs in the annulus between the production tubing and the wellbore. The chemical fluid line connects to the chemical injector portion of the chemical injection mandrel and delivers chemicals to the interior passageway of the mandrel of the chemical injection mandrel where the chemicals mix with the production flow directed to the surface.

Claim (Index 7):
The chemical injection mandrel of  claim 5 , further comprising a crush ring configured to create a seal between the bottom plug and the second threaded opening when the bottom plug is fully inserted into the second threaded opening.
