DOWNHOLE FLOW-METER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18080509 titled 'DOWNHOLE FLOW-METER

The abstract describes a downhole flowmeter assembly for use in a wellbore, featuring a spinner assembly with pitched blades that rotate in response to the flow of wellbore fluid, allowing for the determination of flow velocity. The assembly also includes an oleophobic coating on the hub and blades.

  • The assembly is designed to be placed in a wellbore to measure the flow of wellbore fluid.
  • The spinner assembly consists of a hub and pitched blades that rotate in response to the fluid flow.
  • The speed of rotation of the hub can be used to calculate the velocity of the fluid flow.
  • An oleophobic coating is applied to the hub and blades to prevent the buildup of materials on the surfaces.
  • This technology provides a reliable and accurate method for measuring flow velocity in a wellbore environment.

Potential Applications: - Oil and gas drilling operations - Geothermal energy production - Groundwater monitoring

Problems Solved: - Accurate measurement of flow velocity in wellbores - Prevention of material buildup on flowmeter components

Benefits: - Improved efficiency in wellbore operations - Enhanced accuracy in flow measurement - Extended lifespan of flowmeter components

Commercial Applications: Title: "Advanced Downhole Flowmeter Assembly for Precise Fluid Flow Measurement" This technology can be utilized in various industries such as oil and gas, geothermal energy, and environmental monitoring. It offers a reliable solution for measuring flow velocity in wellbores, leading to improved operational efficiency and accuracy in fluid flow monitoring.

Questions about Downhole Flowmeter Assembly: 1. How does the oleophobic coating on the hub and blades contribute to the performance of the flowmeter assembly? The oleophobic coating helps prevent the buildup of materials on the surfaces of the hub and blades, ensuring accurate and reliable flow measurement. 2. What are the key advantages of using a spinner assembly with pitched blades in a downhole flowmeter? The spinner assembly with pitched blades allows for the measurement of flow velocity based on the rotation of the hub, providing a precise and efficient method for monitoring fluid flow in wellbores.


Original Abstract Submitted

A downhole flowmeter assembly includes a main body configured to be disposed in a wellbore and a spinner assembly comprising a hub from which radially extends a plurality of pitched blades. The hub is configured to rotate in response to a flow of wellbore fluid across the blades, and a velocity of the flow can be determined from a speed of rotation of the hub. The assembly also includes an oleophobic coating disposed at least partially on the hub and the plurality of pitched blades.
