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.

油井渗漏是加拿大的一个主要问题，包括石油渗漏和温室气体排放。发生泄漏是因为威尔斯井没有有效地固井。改进这一进程的困难有三方面。(i)在固井过程中，关于流体的实际位置，几乎无法测量。(ii)对于陆上威尔斯井，在放置后直接评价水泥质量并不常见。这方面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，即对泄漏作出反应。在该项目中，研究人员将开发固井过程的预测模型和模拟。他们将与加拿大主要服务公司和一个广泛的利益攸关方指导委员会合作开展这项工作，以确保适用性。在开发了能够进行物理预测和改进设计的工程工具之后，这些设计工具将免费分发给加拿大的利益攸关方，并以其他研究小组能够为今后的开发和使用作出贡献的方式加以安排。这将为理解固井工艺建立一个共同的基线，并使知识和设计实践方面的共同进步成为可能。
