Chemical deepwater stimulation systems and methods

摘要

Systems and methods for performing operations on a well include first and second flow control devices positioned between upper and lower sections of a conduit. An upper connector assembly engaged with the upper section includes connectors adapted for connection to a chemical stimulation device, a blowout preventer, or other well intervention apparatuses. A lower connector assembly engaged with the lower section includes connectors adapted for connection to a chemical stimulation device, a running tool, wellbore conduits, or other well intervention apparatuses. The two connector assemblies, above and below the flow control devices, enable sequential or simultaneous operations to be performed, and can enable operations to be performed independent of the state of the flow control devices.

主权项

1. A system for performing operations on a well, the system comprising:
a conduit having an upper section and a lower section; a first flow control device positioned between the upper section and the lower section; a second flow control device positioned beneath the first control device and between the upper section and the lower section; and an upper connector assembly engaged with the upper section, wherein the upper connector assembly comprises:
a first flow cross member in fluid communication with the first flow control device, wherein the first flow cross member enables fluid flow in at least two directions;a first connector connected to a chemical stimulation device; anda top connector connected to a blowout preventer, a well intervention apparatus, or combinations thereof, wherein the upper connector assembly enables simultaneous or combined operations performed using the chemical stimulation device, the blowout preventer, the well intervention apparatus, or combinations thereof.
