Visuray Advances VR360 Well Integrity Services into Commercial Deployment.
Unlock reliable well integrity data for annuli-A & -B simultaneously, empowering informed decision-making and productivity.
Currently available on a restricted basis, with commercial rollout in September 2026 across the U.S., Middle East, and North Sea.
- Direct measurement independent of well bore properties.
- Provides real-time data with direct counts of photons.
- Insensitive to de-bonding, X-rays pass straight through unaffected.
- Identify radial density features at multiple depths of investigation.
- Produces cement distribution maps behind multi-casing, unaffected by micro-annulus. The analysis produces an easily readable cement map “image” in real-time, indicating channels in the cement, their depth, and location.
- Top of Cement behind 9⅝" casing visible around 75 meter.
- 13½" Shoe visible around 40-45 meters.
- 13 ⅜" Rathole visible at 45 meter.

The World's First Downhole
X-ray Technology Solution.
Density measurements behind multiple strings. Unaffected by micro annulus, delamination, uncemented inner annulus, and foam cement. The VR360 produces maps of the cement located in the annuli between steel well casings using powerful X-rays, akin to an inside-out CAT scan. As the VR360 is conveyed through the well, fan-shaped ultra-powerful X-ray beams radiate through layers of steel, cement, and rock.
The X-ray beams interact with the atomic structure of the materials surrounding the tool, and X-ray photons scatter from the materials and are captured by a cylindrical array of detectors within the tool. The number of photons measured by the detectors relates to the density of the materials the photons interacted with.
The information collected relates to the three-dimensional distribution of material densities around the tool. It is transmitted to the surface and processed in real-time to produce a map of the cement annuli in the borehole. Channels in the cement are easily identifiable and are highlighted with their depth position and which annuli they are located in, providing clients with unambiguous data to make rapid decisions regarding the integrity of the well.
Visuray has successfully validated the VR360 functions in alignment with both its design intent and market needs, as demonstrated through extensive testing at various third-party facilities.
The resulting data meets the stringent requirements of our industry partners, enabling the generation of high-resolution logs and cement maps across multiple distinct annuli surrounding the borehole. These maps clearly display the location, depth, and azimuthal position, as well as the specific annulus in which any anomalies are identified.

VR360
VR360 well integrity diagnostics is entering early commercial deployment.
Your Team With Reliable Insights.
Like knocking on a wall to find a stud, existing acoustic technology can’t see behind the 2nd layer of casing, and the diagnostic from the 1st layer of casing often leaves guesswork.
Visuray X-ray technology produces clear data behind both layers of casing.
