Seeing Is Believing. VR360 Well Integrity Diagnostics.
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.
The Problem.
- Well maintenance decisions are made with inconclusive data about cement integrity, leading to unnecessary costs.
- The lack of confidence in diagnostics behind the 2nd casing string increases cost of well interventions.
- Existing diagnostic methods have inherent limitations, resulting in inaccurate and uncertain data.
Our Solution.
- X-ray technology overcomes the limitations of existing acoustic technologies, providing reliable data for definitive answers.
- Visuray’s VR360 platform is uniquely capable of diagnostics in the annuli A- & B (1st & 2nd casing strings).
- Diagnostics at the well site allow operators to make decisions in real-time and avoid unnecessary, costly well interventions.

Technology Introduction.
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.
