ConocoPhillips and Statoil Petroleum AS have signed a joint sponsorship development agreement with Visuray Technology Limited, to fund the development of novel downhole technology that can evaluate the integrity of cement behind multiple casing strings in oil and gas wells.
The new technology, the VR360* Diagnostic Cement Evaluation Tool, will produce a full 3D cement map and complement traditional ultrasonic measurements, which are very sensitive to the cement bond between the cement and the inner casing wall. The development of the VR360 tool was initially stimulated by regulatory focus on deepwater wells, although a similar focus on the abandonment of wells in old fields has opened a new and important market for the service. In both applications, the VR360 tool has the potential to obtain valuable information. Value creation will be significant in the relevant well applications.
The goal of the joint industry project is to deliver a number of downhole prototype tools with a range of external diameters. The project is effective from 18 December 2017 and is expected to last three years, during which time other oil companies may consider joining the project. The prototypes will be jointly tested in oil and gas wells by the parties in the project.
The VR360 tool will be built upon foundational X-ray technology developed by Visuray, known as the Downhole X-Ray Platform. Visuray’s first tool from the Downhole X-Ray Platform, the VR90* Downhole X-Ray Diagnostic Tool, has proven well inspection applications and has been used commercially in wells all over the world.
”Visuray is excited to be working with ConocoPhillips and Statoil Petroleum AS,’ said Kambiz Safinya, Group CEO of Visuray. ‘This joint sponsorship development project is an important investment in the X-ray method to significantly improve the evaluation of cement integrity in oil and gas wells.“
Visuray is an oilfield service company that is pioneering downhole X-ray diagnostics to mitigate the risks oil companies face by giving them the power to see with certainty and act with confidence. The Visuray Downhole X-Ray Platform is a family of services that allows oil companies to see inside their wells, while charting a path forward to improve well integrity, and eliminate radioactive materials from the oilfield. Visuray has offices in Malta, Stavanger, Houston, Moscow, and Kuwait. For more information, visit www.visuray.com.
