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 5):
A chemical injection mandrel for injecting chemicals comprising:\n a mandrel comprising a hollow interior passageway and a mandrel injection port; and a chemical injector disposed on an exterior surface of the mandrel, the chemical injector comprising:\n a housing comprising:\n a first threaded opening that extends into a portion of a first cavity, \n a second threaded opening that extends into a portion of a second cavity, \n a control port that fluidly connects the first cavity to the second cavity, and \n a communication port that fluidly connects the second cavity to a chemical outlet port, \n \n a chemical injection port having an inlet end configured to receive fluid flow from a chemical injection line and an outlet end that directs the fluid flow to the control port, wherein the chemical injection port is inserted into the first threaded opening, \n a bottom plug inserted into the second threaded opening, and \n a bellows having a first distal end connected to the bottom plug and a second distal end connected to a dart configured to controllably open and close the communication port, \n wherein application of a predetermined amount of fluid pressure from the chemical injection line to the chemical injection port and the control port compresses the bellows and withdraws the dart from the communication port, allowing fluid flow to the chemical outlet port and into the hollow interior passageway of the mandrel via the mandrel injection port, and wherein the chemical injection mandrel is configured to be disposed on a distal or near-distal end of production tubing and the chemical injection line is configured to be disposed in an annulus between the production tubing and a wellbore.
