Schlumberger is the world's largest provider of technology, services, software, and project management to thepetroleum industry. Schlumberger would like to use cellulose nanocrystals (CNCs) in a variety of fluids relatedto oil & gas extraction in an effort to improve their rheological performance, colloidal stability, mechanicalstrength, and increase their renewable/biodegradable content. However, CNCs are thermally unstable above150 degrees C, which makes them unsuitable for such applications.This project is a continuation on an Engage Grant and aims to produce CNCs that are more thermally andcolloidally stable and that do not lose their favourable properties at high temperatures. In our preliminary study,we produced CNCs with new acids and new acid combinations that allowed us to tailor particle size,thermal/colloidal stability; however, the stability was still not sufficient for oil & gas applications (e.g., 250degrees C, 20,000 psi and brine-level salt conditions). This current project will elucidate the dominant factorsresponsible for CNC thermal stability in both dry and wet conditions and will examine CNC performance inbrine and cement foams. We will also investigate a new surface modification route for CNCs, which will bedone during the CNC production, as a method to impart steric stabilization. We will compare the thermal,chemical, rheological and physical properties of the improved-stability CNCs to more conventional CNCs.CNCs are a Canadian innovation produced from wood pulp with potential application in paints, packaging,food, and composites, however oil & gas fluids would represent the first high volume application. Through thiswork, Schlumberger will be able to assess CNCs in various applications which will give them a significantmarket advantage. The IP developed will be exploited by Schlumberger and their customers in Canada. We arecommitted to helping the forestry and cleantech sectors by developing products with a greener footprint. Theimpact of this work will be economically significant for Canada, will lead to job creation in Canada and willensure that we remain at the forefront of CNC discoveries.

Schlumberger是世界上最大的技术，服务，软件和项目管理提供商。 Schlumberger希望使用纤维素纳米晶体（CNC）在与油气提取相关的多种流体中，以提高其流变性能，胶体稳定性，机械稳定性并增加其可再生/可生物降解含量。但是，CNC在150摄氏度上的热不稳定，这使得它们不适合这种应用。该项目是接合赠款的延续，旨在产生更热和固定稳定的CNC，并且在高温下不会失去其有利的特性。在我们的初步研究中，我们生产了具有新酸和新酸组合的CNC，使我们能够量身定制粒径，热/胶体稳定性。但是，稳定性仍然不足以用于油气应用（例如250度C，20,000 psi和盐水水平的盐条件）。当前的项目将在干燥和湿条件下阐明CNC热稳定性的主要因素，并将检查CNC性能的脑和水泥泡沫。我们还将研究CNC的新的表面修饰途径，该途径将在CNC生产过程中Bedone，作为一种赋予空间稳定的方法。我们将比较提高稳定性CNC的热，化学，流变学和物理性质与更常规的CNCs.cncs是由木浆产生的加拿大创新，具有潜在的涂料，包装，食物和复合材料，但是油气和气体液体代表了第一个高体积应用。通过这项工作，Schlumberger将能够在各种应用中评估CNC，这将为他们带来显着的市场优势。 Schlumberger及其在加拿大的客户将利用开发的IP。我们陆续通过更绿色的足迹开发产品来帮助林业和清洁技术领域。这项工作的影响对于加拿大具有经济意义，将导致在加拿大创造就业机会，并将保持我们仍然处于CNC发现的最前沿。
