Subsurface Sensing and Flow Control

Subsurface Sensing and Flow Control

Subsurface technology and engineering research addresses major technical and socio-political issues regarding energy production and storage and the management of energy waste streams in the subsurface.

Sandia and our partners are combining new methods for exciting and sensing signals using cement-embedded sensors, downhole fiber optic continuous sensing, and near real-time failure analysis to ensure wellbore integrity.

Why sensors?

In industry, cement is a barrier that is critical to the performance of a wellbore. However, cement is vulnerable to damage. Ensuring wellbore integrity requires lifetime monitoring of cement integrity, especially when the well is in service, not just after cement jobs or during work overs.

Cement quality monitoring is typically performed just following cement emplacement and curing, and sporadically, if at all, during wellbore use in production, injection, or monitoring. Multiple casing strings with cement are difficult to examine and interpret. We want to discover how long term, continuous monitoring of wellbore structural health can be accomplished as safely, efficiently, and economically as possible.


Sandia is partnering with Los Alamos National Laboratories, University of Texas – Bureau of Economic Geology, and Purdue University on an integrated program that combines multiple new ways to monitor and analyze wellbore integrity.
