See our Downhole X-Ray
Diagnostic Service in action

The Visuray® VR90® tool offers a new wireline diagnostic service that uses ground-breaking X-ray technology to provide reliable downhole imaging in any well production fluid – allowing you to see with certainty and act with confidence.

A Proven Track Record

Field experience with the VR90 tool has demonstrated the value that the service brings. In one well in the Netherlands, quantitative Visuray measurements resolved fine details of a disconnected coiled tubing string, providing interactive 3D images of the target surface that enabled successful recovery operations. On a well in the North Sea, VR90 images identified and measured flapper operation in several positions that subsequently led to the successful installation of a wireline insert downhole safety valve that enabled the well to be put back on production. In another successful case in the North Sea, a VR90 tool was tractored over 1500 m to define and help recover a fish that could not be identified by conventional technology.

How Does It Work?

The VR90 tool taps into the technology innovations of the Visuray Downhole X-Ray Platform. It is a forward-viewing tool that generates X-rays up to energies in excess of 150 keV, and measures the backscattered radiation from objects and fluids directly ahead. The measurements are converted into accurate, measureable and recognizable 2D or 3D representations of the objects seen.

Applications

  • Inspection of completion equipment such as valves and mandrels
  • Classification and quantification of wellbore restrictions and obstructions
  • Determination of shapes and dimensions of dropped objects
  • Identification and characterization of collapsed or split casing
  • Providing input for design of customized fishing tools
  • Inspection of fishing profiles on downhole equipment such as plugs and packers

Benefits

  • Works in all production fluids, and can image sand-covered objects – saving time and money by eliminating the need to displace well fluid, clean up or chemically condition the well.
  • Operates at temperatures up to 212 deg F / 100 deg C and pressures up to 20,000psi / 1,380 bar – providing answers in previously inaccessible environments.
  • Uses inherently safe, electronic X-ray sources – simplifying logistics.
  • Produces real time answers – enabling well-informed decisions anywhere in the world.
  • Works centered or eccentered in the well – for extra operational flexibility.
  • Runs on all types of electric wireline and is compatible with tractors and strokers.
