Title:
DOWNHOLE CHEMICAL INJECTION METHOD AND SYSTEM FOR USE IN ESP APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2015/196062
Kind Code:
A3
Abstract:
Provided is a chemical injection pump (200, 300) that is installed below an electric submersible pump (101). The chemical injection pump is either driven by an electric motor (120) that draws power from the electric submersible pump motor (150) or from energized fluid leaving the electric submersible pump output port. The electric submersible pump provides electric or hydraulic power to run the chemical injection pump. Therefore, no surface chemical injection pump is required and hence less space is needed.
