MULTI-POINT INJECTION SYSTEM FOR OILFIELD OPERATIONS
First Claim
1. A system for injecting an injection fluid in a well, comprising:
- an umbilical disposed in the well, the umbilical being configured to convey the injection fluid;
a plurality of nozzles configured to receive the injection fluid from the umbilical; and
a flow control element associated with each nozzle, each flow control element being configured to control a flow of the injection fluid through the associated nozzle.

Abstract
A system monitors and controls the injection of additives into formation fluids recovered through a well may include a plurality of nozzles that receive the injection fluid from an umbilical disposed in a well. Each nozzle may have an associated flow control element that is configured to affect a flow of the injection fluid ejected through the associated nozzle. The umbilical may include one or more filters positioned in a first of two parallel conduits formed along the umbilical. An occlusion member restricts in a second of the two conduits. The occlusion member permits flow in the second conduit after a predetermined pressure differential exists in the second conduit. The system may include a plurality of pressure sensors disposed along the umbilical, and an injector unit that dispenses fluid into the umbilical. A controller operatively coupled to the injector unit operates the injector in response to measurements from the pressure sensors.
