Well leakage is a major concern in Canada, both in terms of oil seepage and release of greenhouse gases (GHG). Leakage occurs because the wells are not effectively cemented. The difficulty in improving this process is threefold. (i) Very little can be measured during the cementing process, concerning actual placement of fluids. (ii) For onshore wells it is not common to evaluate the cement quality directly, after placement. Logging methods for this are also not precise. (iii) regulatory bodies and producers currently operate in a way that is reactive, i.e. to leakage. In this project the researchers will develop predictive models and simulations of the cementing process. They will do this in collaboration with leading Canadian service companies and with a broad steering committee of stakeholders, to ensure applicability. Having developed engineering tools that enable physical prediction and improved designs, the design tools will be distributed freely to Canadian stakeholders and structured in such a way that other research groups can contribute to future development as well as usage. This will establish a common baseline for understanding of cementing processes and allow communal advances in knowledge and design practices.

就石油渗漏和温室气体（GHG）释放而言，井漏是加拿大的一个主要问题。泄漏的发生是因为井没有得到有效的固井。改进这个过程的困难有三重。 (i) 在固井过程中，关于流体的实际放置，几乎无法测量。 (ii) 对于陆上井，在浇注后直接评估水泥质量的情况并不常见。对此的记录方法也不精确。 (iii) 监管机构和生产商目前的运作方式是被动的，即对泄漏。在这个项目中，研究人员将开发固井过程的预测模型和模拟。他们将与加拿大领先的服务公司和广泛的利益相关者指导委员会合作，以确保适用性。在开发出能够进行物理预测和改进设计的工程工具后，这些设计工具将免费分发给加拿大利益相关者，并以其他研究小组可以为未来的开发和使用做出贡献的方式构建。这将为理解固井过程建立一个共同基线，并促进知识和设计实践的共同进步。
