An online symposium
organized by
Ecole des Ponts ParisTech and LafargeHolcim
under the auspices of the Chair
“Materials Science for Sustainable Construction”
supported by LafargeHolcim

March 24-26 afternoons (European time), 2021

Scope

The cement sheath in oil & gas wells, used since 1903, plays a significant role in ensuring zonal isolation,protecting the tubular against corrosion, and providing mechanical support. With the progressive rarefication of conventional resources, the petroleum industry needs to drill deeper and faces more demanding conditions to ensure the proper execution of cementing operations and long-term cement sheath integrity. Simultaneously, raising public awareness about climate change encourages the cement industry to produce greener cements and improve the produced materials' durability. Bearing these new challenges in mind, we gather specialists from the university and the industry. With their various points of view ranging from fundamental to more practical questions, we hope this three-day workshop will foster interesting discussions on current challenges and future solutions of cement sheath integrity in oil & gas wells.
