Reference number : GC-2017-Q2-00458, amendment number : , agreement type : G, recipient legal name : Cranston, Emily (McMaster University), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Plus Grants for Universities, program name french : Subvention d'engagement partenarial Plus pour les universités, program purpose english : Schlumberger is the world's largest provider of technology, services, software, and project management to the_x000D_
petroleum industry. Schlumberger would like to use cellulose nanocrystals (CNCs) in a variety of fluids related_x000D_
to oil & gas extraction in an effort to improve their rheological performance, colloidal stability, mechanical_x000D_
strength, and increase their renewable/biodegradable content. However, CNCs are thermally unstable above_x000D_
150 degrees C, which makes them unsuitable for such applications._x000D_
This project is a continuation on an Engage Grant and aims to produce CNCs that are more thermally and_x000D_
colloidally stable and that do not lose their favourable properties at high temperatures. In our preliminary study,_x000D_
we produced CNCs with new acids and new acid combinations that allowed us to tailor particle size,_x000D_
thermal/colloidal stability; however, the stability was still not sufficient for oil & gas applications (e.g., 250_x000D_
degrees C, 20,000 psi and brine-level salt conditions). This current project will elucidate the dominant factors_x000D_
responsible for CNC thermal stability in both dry and wet conditions and will examine CNC performance in_x000D_
brine and cement foams. We will also investigate a new surface modification route for CNCs, which will be_x000D_
done during the CNC production, as a method to impart steric stabilization. We will compare the thermal,_x000D_
chemical, rheological and physical properties of the improved-stability CNCs to more conventional CNCs._x000D_
CNCs are a Canadian innovation produced from wood pulp with potential application in paints, packaging,_x000D_
food, and composites, however oil & gas fluids would represent the first high volume application. Through this_x000D_
work, Schlumberger will be able to assess CNCs in various applications which will give them a significant_x000D_
market advantage. The IP developed will be exploited by Schlumberger and their customers in Canada. We are_x000D_
committed to helping the forestry and cleantech sectors by developing products with a greener footprint. The_x000D_
impact of this work will be economically significant for Canada, will lead to job creation in Canada and will_x000D_
ensure that we remain at the forefront of CNC discoveries., program purpose french : Schlumberger is the world's largest provider of technology, services, software, and project management to the_x000D_
