Visuray has a strong IP portfolio and unparalleled expertise in the X-ray domain for deployment in both open- and cased-hole wells.
The company’s unique Downhole X-Ray Platform has initially been used for diagnostic well inspection services. Visuray has now harnessed this Platform to build a full-scale laboratory prototype of an X-ray density logging tool with a response virtually identical to the classic formation density tools using a Cesium137 nuclear source. Moreover, due to the extreme brightness of the X-ray source, Visuray has demonstrated that a 0.01 g/cc accuracy can be achieved logging at as fast as 7,200 feet per hour, significantly faster than today’s best-in-class density logging technology.
Visuray has also harnessed its Downhole X-Ray Platform to build a laboratory equivalent of a conventional neutron porosity logging tool. The Downhole X-Ray Platform therefore promises to displace the conventional nuclear suite of measurements used in formation evaluation and dispense with all nuclear sources. When the combination of equivalent density and neutron porosity measurements is integrated with classic resistivity devices, Visuray’s Downhole X-Ray Platform will then provide a fast and safe triple-combo logging service, free of all nuclear sources, a service Visuray will market as the VRFE72.
In addition to the development of this family of wireline-conveyed tools, the packaging and integration of our Downhole X-Ray Platform is also being adapted for future use in logging-while-drilling applications.
With Visuray’s core competence in developing downhole high-voltage power supplies, high-energy radiation can now be generated electronically. This competence will result in a family of tools that will completely eliminate the use of chemical nuclear sources. This reduces the health and safety risk, improves environmental performance, and meets increasingly stringent governmental regulation arising from security concerns.
