Alberta is full of abandoned and orphan wells; there are 97,000 wells that have not been closed and 71,000 not reclaimed, orphaned and left. When oil and gas wells are no longer productive, if the facility does not have any legal responsibility or is financially unable to pay for abandonment and reclamation costs, wellbores become orphaned and/or abandoned. Current regulatory regimes require projects to be reclaimed, both downhole and at the surface, with significant cost and liability to oil and gas producers. The federal government of Canada plans to spend $1.7 billion to clean up wellbores that have been orphaned and/or abandoned in Western Canada. This is part of their COVID-19 Economic Response Plan for the energy sector to create jobs and clean up the environment. This billion-dollar investment manage inactive wells in Canada is designed to reduce the amount of liabilities that come with the alarming number of inactive wells. In Alberta, these wells are under the jurisdiction of Alberta Energy Regulator (AER) who then delegates clean up responsibilities to the Alberta Orphan Wells Association (OWA) for the continuation of their work of successfully decommissioning wells. From 2002 to 2018, the OWA decommissioned approximately 2,200 orphan wells and reclaimed 800 others. Their work is still ongoing as more than half of Alberta's wells are no longer in production and have been abandoned and left uncleaned. Warner Business Park Ltd. (Warner) has presented a unique solution for Canada's oil and gas industry; to convert inactive wellbore liabilities into renewable energy storage systems through gravitational potential energy. This project will build and implement the first prototype for a downhole well using a training well on site at SAIT.

阿尔伯塔到处都是废弃的和孤儿威尔斯井;有97 000口威尔斯井没有关闭，71 000口井没有被开垦，成为孤儿和离开。当油气井威尔斯不再生产时，如果设施没有任何法律的责任或在经济上无法支付废弃和回收成本，则井筒成为孤儿和/或废弃。目前的监管制度要求项目在井下和地面进行回收，这给石油和天然气生产商带来了巨大的成本和责任。加拿大联邦政府计划花费17亿加元清理加拿大西部地区被遗弃和/或遗弃的钻井。这是他们为能源部门创造就业机会和清洁环境的COVID-19经济应对计划的一部分。这项数十亿美元的投资管理不活跃的威尔斯在加拿大的目的是减少负债数额来与惊人的数量不活跃的威尔斯。在阿尔伯塔，这些油井属于阿尔伯塔能源监管机构（AER）的管辖范围，该机构随后将清理责任委托给阿尔伯塔孤儿威尔斯协会（OWA），以继续其成功退役威尔斯的工作。 从2002年到2018年，OWA退役了大约2,200口孤威尔斯井，并回收了800口。他们的工作仍在进行中，因为阿尔伯塔一半以上的威尔斯油井已不再生产，并已被废弃和未清理。华纳商业园有限公司（华纳）为加拿大的石油和天然气行业提出了一个独特的解决方案;通过重力势能将不活跃的井筒负债转化为可再生能源储存系统。该项目将在SAIT现场使用训练井建造和实施第一个井下井原型。
