Technical System, Method and Use for Online Measuring and Monitoring of the Particle Contents in a Flow of Injection Water in an Underwater Line

A method for online measuring and monitoring of the particle content in an injection water flow, wherein the method makes use of a technical system comprising a data gathering means, a data communication link and a data receiving means, and wherein the data gathering means comprises an image analysis apparatus provided with the following components:

• at least one water sample line provided with an inlet and an outlet;
• at least one pumping means connected, in a flow-communicating manner, to the water sample line;
• at least one light-transparent flow portion disposed along the water sample line;
• at least one camera disposed at a side of the light-transparent flow portion;
• at least one light source disposed at the light-transparent flow portion of the water sample line;
• at least one electronic control means structured for (a) control of the image recording of the camera;
• (b) reception of image material from the camera;
• and (c) transmission of this image material to said data receiving means;
• and
• at least one energy supply for operation of said pumping means, light source, camera and electronic control means,
• wherein the method comprises using a technical system that also comprises an underwater line for containing said injection water flow;
• wherein the method also comprises the following steps:
• (A) disposing at least said water sample line, pumping means, light-transparent flow portion, camera, light source and electronic control means of the image analysis apparatus in a water-tight housing and placing the housing under water;
• (B) connecting, in a flow-communicating manner, the inlet and the outlet of the water sample line to the underwater line at a connection site located between a shipment site for the injection water and an injection well;
• (C) connecting, by means of said data communication link, the image analysis apparatus to a data receiving means located at a distance from the image analysis apparatus;
• (D) transporting, by means of said pumping means, a partial flow of the injection water flow through the water sample line;
• (E) emitting, by means of said light source, light via the light-transparent flow portion of the water sample line and into the camera;
• (F) recording, by means of the electronic control means, said energy supply and the camera, image material of the particle content in said partial flow in the water sample line;
• and
• (G) transmitting, by means of the electronic control means and said energy supply, this image material to the remote data receiving means, whereby image material being transmitted from the image analysis apparatus may be monitored online at a remote site.
